• e-interview: SunSpace to WebCenter migration

  - by me

  I had the pleasure to do an e-interview with Ana Neves around the SunSpace to WebCenter migration project.  Below is the english version of the interview.  Enjoy   Peter, you joined Oracle in 2009 through the acquisition of Sun. Becoming a part of Oracle meant many changes. The internal collaboration platform was one of them, as per a post you wrote back in 2011. Sun had SunSpace. How would you describe SunSpace? SunSpace was the internal Community and Social Collaboration platform for the Sun's Global Sales and Services Organization. SunSpace served around 600 communities with a main focus around technology, products and services. SunSpace was a big success. Within 3 months of its launch SunSpace had over 20,000 users and it won the Atlassian "Not just another wiki" Award for the best use of Confluence (https://blogs.oracle.com/peterreiser/entry/goodbye_sunspace_hello_webcenter). What made SunSpace so special? 1. People centric versus  Web centric The main concept of SunSpace put the person in the middle of everything. All relevant information, resources  etc. where dynamically pushed to a person's  myProfile ( Facebook like interface) based on the person's interest and  needs.  2. Ease to use  SunSpace was really easy to use. We spent a lot of time on social interaction design to optimize the user experience.  Also we integrated some sophisticated technology to hide complexity from the user. As example - when a user added a document to SunSpace - we analyzed the content of the document and suggested related metadata and tags to the user based on a sophisticated algorithm which was integrated with the corporate taxonomy. Based on this metadata the document was automatically shared with the relevant communities.  3. Easy to find One of the main use cases for SunSpace was that  a user could quickly find the content and information they needed for their job.  The search implementation was based on:  optimized search engine algorithm using social value based ranking enhancements community facilitated search optimization  faceted search which recommended highly relevant  content like products, communities and experts 4. Social Adoption  - How to build vibrant communities You can deploy the coolest social technology but what if the users are not using it?   To drive user adoption we implemented two  complementary models: 4.1 Community Methodology  We developed a set of best practices on how to create, run and sustain communities including: community structure and types (e.g. Community of Practice, Community of Interest etc.) & tips and tricks on how to build a "vibrant " communities, Community Health check etc.  These best practices where constantly tuned and updated by the community of community drivers. 4.2. Social Value System To drive user adoption there is ONE key  question you  have to answer for each individual user: What's In It For Me (WIIFM) We developed a Social Value System called Community Equity which measures the social value flow between People, Content and Metadata. Based on this technology we added "Gamfication" techniques (although at that time this term did not exist ) to SunSpace to honor people for the active contribution and participation.  As example: All  social credentials a user earned trough active community participation where dynamically displayed on her/his myProfile. How would you describe WebCenter? Oracle WebCenter (@oraclewebcenter) is the Oracle's  user engagement platform for social business. It helps people work together more efficiently through contextual collaboration tools that optimize connections between people, information, and applications and ensures users have access to the right information in the context of the business process in which they are engaged. Oracle WebCenter can help your organization deliver contextual and targeted Web experiences to users and enable employees to access information and applications through intuitive portals, composite applications, and mash-ups. How does it compare to SunSpace in terms of functionality? Before I answer this question, I would like to point out some limitation we started to see with the current SunSpace implementation. Due to the massive growth of the user population (>20,000 users), we experienced  performance and scalability challenges with the current technology. Also at the time - Sun Internal Communications and SunIT planned to replace the entire Sun Intranet with SunSpace. We  kicked-off a project to evaluate the enterprise level technology which eventually would replace the good old static Intranet.  And then Oracle acquired Sun. We already had defined the functional requirements for the Intranet replacement with a Social Enterprise Stack and we just needed to evaluate the functional requirements against WebCenter   Below are the summary of this evaluation  MyProfile SunSpace WebCenter How WebCenter Works Home MyProfile: to access, click on your name at the top of any WebCenter page Your name, title, and reporting line are displayed.  Sub-tabs show your activity stream (Activities); people in your network (Connections); files you have uploaded (Documents); your contact information (Organization); and any personal information you wish to share (About).   Files MyFiles Allows you to upload, download and store documents or wiki pages within folders and subfolders.  The WebDav interface allows you to download / upload files / folders with a simple drag and drop to / from your local machine.  Tagging is supported and recommended. Network HomeMyConnections Home: displays the activity stream of individuals in your network.MyConnections: shows individuals in your network.  Click on a person's name to see their contact info and link to their profile. Status Updates MyProfle > Activties Add and displays  your recent activties and status updates. Watches Preferences > Subscriptions > Current Subscriptions Receive email notifications when  pages / spaces you watch are modified. Drafts N/A WebCenter does not support Drafts Settings Preferences: to access, click on 'Preferences' at the top of any WebCenter page Set your general preferences, as well as your WebCenter messaging, search and mail settings. MyCommunities MySpaces: to access, click on 'Spaces' at the top of any WebCenter page Displays MySpaces (communities you are a member of); and Recent Spaces (communities you have recently visited). Community SunSpace Webcenter How Webcenter Works Home Home Displays a community introduction and activity stream.  Members can add messages, links or documents via the Community Message Board. No Top Contributors widget. People Members Lists members of the community. The Mail All Members feature allows moderators and participants to send a message to all members of the community. Membership Management can be found under > Manage > Members News News Members can post and access latest community news and they can subscribe to news using an RSS reader Documents Documents Allows community members to upload, download and store documents or wiki pages within folders and subfolders.  The WebDav interface allows participants to download / upload files / folders with a simple drag and drop to / from your local machine.  Tagging is supported and recommended. Wiki Wiki Allows community members to create and update web pages with a WYSIWYG editor.  Note: WebCenter does not support macros or portlet embedding. Forum Forum Post community forum topics. Contribute to community forum conversations.  N/A Calendar Update and/or view the Community Calendar. N/A Analytics Displays detailed analytics data (views,downloads, unique users etc.) for Pages, Wiki, Documents, and Forum in a given community space. What is the adoption of WebCenter at Oracle? The entire Intranet serving around 100,000 users  is running on WebCenter Content.  For professional communities we use WebCenter Portal and Spaces. Currently we have around 6,000 community spaces with  around 40,000 members.  Does Oracle have any metrics to assess usage and impact of WebCenter? Can you give us some examples? Sure -  we have a lot of metrics   For the Intranet we use traditional metrics like pageviews, monthly unique visitors and unique visits.  For Communities we use the WebCenter Portal/Spaces analytics service which gives as a wealth of data. The key metrics we track are: Space traffic (PageViews, Unique Users) Wiki,Documents (views, downloads etc.) Forum (users, views, posts etc.) Registered members over time  Depending on the community we can filter/segment the metrics by User Properties e.g. Country, Organization, Job Role etc. What are you doing to improve usage and impact? 1. We  integrating the WebCenter social services/fabric into all  main business applications. As example The Fusion CRM deployment is seamless integrated with Oracle Social Network (OSN) and all conversation around an opportunity or customer engagement is  done in OSN (see youtube video). 2. We drive Social Best Practice trough a program called "Social Networking & Business Collaboration (SNBC) program" You worked both with WebCenter and SunSpace. Knowing what you know today, if you had the chance to choose between the two, which one would you choose? Why? That's a tricky question   In the early days of  the Social Enterprise implementation (we started SunSpace in 2006), we needed an agile and easy to deploy technology to keep up with the users requirements. Sometimes we pushed two releases per day  and we were in a permanent perpetual beta mode - SunSpace was perfect for that.  After the social implementation matured over time - community generated content became business critical and we saw a change in the  requirements from agile to stability, scalability and reliability  of the infrastructure.  WebCenter is the right choice for such an enterprise-level deployment.  You are a WebCenter Evangelist at Oracle. What do you do as part of that role? Our  role is to help position Oracle as one of the key thought leaders and solutions provider for Social Business. In addition we drive social innovation trough our Oracle Appslab  team. Is that a full time role? Yes  How many other Evangelists are there in Oracle? We are currently 5 people in the WebCenter evangelist team (@webcentervoices): Christian Finn (@cfinn) leads the team - Christian came from the Microsoft Sharepoint product management team and is a recognized expert in Social Business and Enterprise Collaboration. Noël Jaffré  (@noeljaffre) is our Web Experience Management (WEM) guru and came to Oracle via FatWire acquisition (now WebCenter Sites). Jake Kuramoto (@theapplab) is part of the Oracle AppsLab innovation  team - Jake is well known as  the driving force behind  http://theappslab.com  a blog around social and innovation.  Noel Portugal (@noelportugal) is a developer in the Oracle AppsLab innovation team - he is the inventor of OraTweet - Oracle's internal tweeting platform  Peter Reiser (@peterreiser) is  a Social Business guru and the inventor of SunSpace and Community Equity.  What area of the business do you and the rest of the Evangelists sit in? What area of the organisation is responsible for WebCenter? We are part of the WebCenter product management  organization.  Is WebCenter part of the Knowledge Management strategy? Oracle WebCenter is the Oracle's user engagement platform for social business. It brings together the most complete portfolio of portal, web experience management, content, social and collaboration technologies into a single product suite and is the product foundation of the Oracle Knowledge Management strategy.  I am aware Oracle also uses Beehive internally. How would you describe Beehive? Oracle Beehive provides an integrated set of communication and collaboration services built on a single scalable, secure, enterprise-class platform Beehive is  internally used for enterprise wide mail, calendar and real collaboration (Web conferencing) services.  Are Beehive and WebCenter connected? Historically Beehive and WebCenter Portal & Content had some overlap in functionally. (Hey - if  a company has an acquisition strategy to strengthen its product offering and accelerate  innovation, it's pretty normal that functional overlap exists  :- )) A key objective of the WebCenter strategy is  to combine all social and collaboration offerings under the WebCenter product family. That means that certain Beehive components  will be integrated into the overall WebCenter product offering.  Are there any other internal collaboration tools at Oracle? Which ones There here are two other main social tools which are widely used at Oracle  Oracle Connect was the first social tool the Oracle AppsLab team created in 2007 - see (Jake's blog post for details). It is still extensively used. ... and as a former Sun guy I like this quote from the blog post:  "Traffic to Connect peaked right after the Sun merger in 2010, when it served several hundred thousand pageviews each month; since then, traffic has subsided, but still averages tens of thousands of pageviews to several thousand users each month." Oratweet - Oracle internal microblogging platform has been used since June 2008 and it is still growing.  It's entirely written in Oracle Application Express (APEX) which is a rapid web application development tool for the Oracle database. Wanna try it out? Here you can download the code.  What is Oracle's strategy regarding (all these) collaboration tools? Pretty straight forward. The strategy is to seamless  integrate the WebCenter social & collaboration services into all Business Applications to help customers to socialize their enterprise.

The increasing focus on customer centricity, enhanced and speedier product development capabilities, and compliance with regulatory changes has forced companies to rethink well-entrenched policy administration processes. In previous Oracle Insurance blogs I’ve highlighted industry research pointing to policy administration replacement as a top IT priority for carriers. It is predicted that by 2013, the global IT spend on policy administration alone is likely to be almost 22 percentage of the total insurance IT spend. To achieve growth, insurers are adopting new pricing models, enhancing distribution reach, and quickly launching new products and services—all of which depend on agile and effective policy administration processes and technologies. Next month speakers from Oracle Insurance and Capgemini Financial Services will discuss how insurers can competitively drive high performance through policy administration replacement during a free, one-hour webcast hosted by LOMA. Roger Soppe, Oracle senior director, Insurance Strategy, together with Capgemini’s Lars Ernsting, leader, Life & Pensions COE, and Scott Mampre, vice president, Insurance, will be the speakers. Specifically, they’ll be highlighting: How replacing a legacy policy administration system with a modern, flexible platform optimizes IT and operations costs, creates consistent processes and eliminates resource redundancies How selecting the right partner with the best blend of technology, operational, and consulting capabilities, is an important pre-requisite to unlock high performance from policy administration transformation to achieve product, operational, and cost leadership  The value of outsourcing closed block operations We look forward to your participation on Thursday, July 14, 11:00 a.m. ET. Please register now. Helen Pitts is senior product marketing manager for Oracle Insurance's life and annuities solutions.

• Taking HRMS to the Cloud to Simplify Human Resources Management

  - by HCM-Oracle

  By Anke Mogannam With human capital management (HCM) a top-of-mind issue for executives in every industry, human resources (HR) organizations are poised to have their day in the sun—proving not just their administrative worth but their strategic value as well.  To make good on that promise, however, HR must modernize. Indeed, if HR is to act as an agent of change—providing the swift reallocation of employees  and the rapid absorption of employee data required for enterprises to shift course on a dime—it must first deal with the disruptive change at its own front door. And increasingly, that means choosing the right technology and human resources management system (HRMS) for managing the entire employee lifecycle. Unfortunately, for most organizations, this task has proved easier said than done. This is because while much has been written about advances in HRMS technology, until recently, most of those advances took the form of disparate on-premises solutions designed to serve very specific purposes. Although this may have resulted in key competencies in certain areas, it also meant that processes for core HR functions like payroll and benefits were being carried out in separate systems from those used for talent management, workforce optimization, training, and so on. With no integration—and no single system of record—processes were disconnected, ease of use was impeded, user experience was diminished, and vital data was left untapped.  Today, however, that scenario has begun to change, and end-to-end cloud-based HCM solutions have moved from wished-for innovations to real-life solutions. Why, then, have HR organizations been so slow in adopting them? The answer—it would seem—is, “It’s complicated.” So complicated, in fact, that 45 percent of the respondents to PwC’s “Annual HR Technology Survey” (for 2013) reported having no formal HR software roadmap, and 40 percent stated that they “did not know” whether their organizations would be increasing their use of cloud or software as a service (SaaS) for HR.  Clearly, HR organizations need help sorting through the morass of HR software options confronting them. But just as clearly, there’s an enormous opportunity awaiting those that do. The trick will come in charting a course that allows HR to leverage existing technology while investing in the cloud-based solutions that will deliver the end-to-end processes, easy-to-understand analytics, and superior adaptability required to simplify—and add value to—every aspect of employee management. The Opportunity therefore is to cut costs, drive Innovation, and increase engagement by moving to cloud-based HCM.  Then you will benefit from one Interface, leverage many access points, and  gain at-a-glance insight across your entire workforce. With many legacy on-premises HR systems not being efficient anymore and cloud-based, integrated systems that span the range of HR functions finally reaching maturity, the time is ripe for moving core HR to the cloud. Indeed, for the first time ever there are more HRMS replacement initiatives than HRMS upgrade initiatives under way, and the majority of them involve moving to the cloud per Cedar Crestone’s 2013-2014 HRMS survey. To learn how you can launch your own cloud HCM initiative and begin using HR to power the enterprise, visit Oracle HRMS in the Cloud and Oracle’s new customer 2 cloud program.

• Entity Framework 4 "Generate Database from Model" to SQLEXPRESS mdf results in "Could not locate ent

  - by InfinitiesLoop

  I'm using Visual Studio 2010 RTM. I want to do model-first, so I started a new MVC app and added a new blank edmx. Created a few entities. No problem. Then I "Generate Database from Model", and allow the dialog to create a new database for me, which it does successfully as 'mydatabase.mdf' in the app's App_Data directory. Then I open the generated sql file (in Visual Studio). To run it of course I have to give it a connection. I am not sure if it's right, but I used '.\SQLEXPRESS' and Windows authentication. No idea how I'd tell it where the MDF is. Then the problem -- upon executing it, I get: Msg 911, Level 16, State 1, Line 1 Could not locate entry in sysdatabases for database 'mydatabase'. No entry found with that name. Make sure that the name is entered correctly. And indeed there were no tables created in the MDF. So... what am I doing wrong, or am I off my rocker expecting this to work? :)

• Database Change Management - Setup for Initial Create Scripts, Subsequent Migration Scripts

  - by Martin Aatmaa

  I've got a database change management workflow in place. It's based on SQL scripts (so, it's not a managed code-based solution). The basic setup looks like this: Initial/ Generate Initial Schema.sql Generate Initial Required Data.sql Generate Initial Test Data.sql Migration 0001_MigrationScriptForChangeOne.sql 0002_MigrationScriptForChangeTwo.sql ... The process to spin up a database is to then run all the Initlal scripts, and then run the sequential Migration scripts. A tool takes case of the versioning requirements, etc. My question is, in this kind of setup, is it useful to also maintain this: Current/ Stored Procedures/ dbo.MyStoredProcedureCreateScript.sql ... Tables/ dbo.MyTableCreateScript.sql ... ... By "this" I mean a directory of scripts (separated by object type) that represents the create scripts for spinning up the current/latest version of the database. For some reason, I really like the idea, but I can't concretely justify it's need. Am I missing something? The advantages would be: For dev and source control, we would have the same object-per-file setup that we're used to For deployment, we can spin up a new DB instance to the latest version either by running the Initial+Migrate, or by running the scripts from Current/ For dev, we do not need a DB instance running in order to do development. We can do "offline" development on the Current/ folder. The disadvantages would be: For each change, we need to update the scripts in the Current/ folder, as well as create a Migration script (in the Migration/ folder) Thanks in advance for any input!

• MySQL Relational Database Foreign Key

  - by user623879

  To learn databasing, I am creating a movie database. To associate multiple directors with a movie, I have the following schema: movie(m_ID, ....) m_director(dirID, dirName)//dirID is a autoincrement primary key m_directs(dirID, m_ID) //dirID, m_ID are set as foreign Keys in the mysql database(InnoDB engine) I have a program that connects to the db that needs to add a movie to the database. I can easily add a new entry to the movie table and the m_director table, but I am having trouble adding a entry in the m_directs table. INSERT INTO m_director (dirName) VALUES("Jason Reitman"); INSERT INTO m_directs (dirID, m_ID) VALUES(LAST_INSERT_ID(), "tt0467406"); I am using this sql statement to insert a new director and add the association to the movie. I know the primary key of the movie, but I don't know the dirID, so I use LAST_INSERT_ID() to get the last id of the director just inserted. The problem I am having is that I get the following error: MySql.Data.MySqlClient.MySqlException (0x80004005): Cannot add or update a child row: a foreign key constraint fails (`siteproducts`. `m_directs`, CONSTRAINT `m_directs_ibfk_2` FOREIGN KEY (`dirID`) REFERENCES `m_directs` (`dirID`) ON DELETE CASCADE ON UPDATE CASCADE) Any ideas?

• Get id when inserting new row using TableAdapter.Update on a file based database

  - by phq

  I have a database table with one field, called ID, being an auto increment integer. Using a TableAdapter I can read and modify existing rows as well as create new ones. However if I try to modify a newly inserted row I get an DBConcurrencyException: OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Shift.mdb;Persist Security Info=True"); ShiftDataSetTableAdapters.ShiftTableAdapter shiftTA = new ShiftDataSetTableAdapters.ShiftTableAdapter(); shiftTA.Connection = conn; ShiftDataSet.ShiftDataTable table = new ShiftDataSet.ShiftDataTable(); ShiftDataSet.ShiftRow row = table.NewShiftRow(); row.Name = "life"; table.Rows.Add(row); shiftTA.Update(row); // row.ID == -1 row.Name = "answer"; // <-- all fine up to here shiftTA.Update(row); // DBConcurrencyException: 0 rows affected Separate question, is there any static type of the NewShiftRow() method I can use so that I don't have to create table everytime I want to insert a new row. I guess the problem in the code comes from row.ID that is still -1 after the first Update() call. The Insert is successful and in the database the row has a valid value of ID. How can I get that ID so that I can continue with the second Update call? Update: IT looks like this could have been done automatically using this setting. However according to the answer on msdn social, OLEDB drivers do not support this feature. Not sure where to go from here, use something else than oledb? Update: Tried SQLCompact but discovered that it had the same limitation, it does not support multiple statements. Final question: is there any simple(single file based) database that would allow you to get the values of a inserted row.

• SQL Server 2005 database design - many-to-many relationships with hierarchy

  - by Remnant

  Note I have completely re-written my original post to better explain the issue I am trying to understand. I have tried to generalise the problem as much as possible. Also, my thanks to the original people who responded. Hopefully this post makes things a little clearer. Context In short, I am struggling to understand the best way to design a small scale database to handle (what I perceive to be) multiple many-to-many relationships. Imagine the following scenario for a company organisational structure: Textile Division Marketing Division | | ---------------------- ---------------------- | | | | HR Dept Finance Dept HR Dept Finance Dept | | | | ---------- ---------- ---------- --------- | | | | | | | | Payroll Hiring Audit Tax Payroll Hiring Audit Accounts | | | | | | | | Emps Emps Emps Emps Emps Emps Emps Emps NB: Emps denotes a list of employess that work in that area When I first started with this issue I made four separate tables: Divisions - Textile, Marketing (PK = DivisionID) Departments - HR, Finance (PK = DeptID) Functions - Payroll, Hiring, Audit, Tax, Accounts (PK = FunctionID) Employees - List of all Employees (PK = EmployeeID) The problem as I see it is that there are multiple many-to-many relationships i.e. many departments have many divisions and many functions have many departments. Question Giving the database structure above, suppose I wanted to do the following: Get all employees who work in the Payroll function of the Marketing Division To do this I need to be able to differentiate between the two Payroll departments but I am not sure how this can be done? I understand that I could build a 'Link / Junction' table between Departments and Functions so that I can retrieve which Functions are in which Departments. However, I would still need to differentiate the Division they belong to. Research Effort As you can see I am an abecedarian when it comes to database deisgn. I have spent the last two days resaerching this issue, traversing nested set models, adjacency models, reading that this issue is known not to be NP complete etc. I am sure there is a simple solution?

• Database design for credit based purchases

  - by FreshCode

  I need an elegant way to implement credit-based purchases for an online store with a small variety of products which can be purchased using virtual credit or real currency. Alternatively, products could only be priced in credits. Previous work I have implemented credit-based purchasing before using different product types (eg. Credit, Voucher or Music) with post-order processing to assign purchased credit to users in the form of real currency, which could subsequently be used to discount future orders' charge totals. This worked fairly well as a makeshift solution, but did not succeed in disconnecting the virtual currency from the real currency, which is what I'd like to do, since spending credits is psychologically easier for customers than spending real currency. Design I need guidance on designing the database correctly with support for the simultaneous bulk purchase of credits at a discount along with real currency products. Alternatively, should all products be priced in credits and only credit have a real currency value? Existing Database Design Partial Products table: ProductId Title Type UnitPrice SalePrice Partial Orders table: OrderId UserId (related to Users table, not shown) Status Value Total Partial OrderItems table (similar to CartItems table): OrderItemId OrderId (related to Orders table) ProductId (related to Products table) Quantity UnitPrice SalePrice Prospective UserCredits table: CreditId UserId (related to Users table, not shown) Value (+/- value. Summed over time to determine saldo.) Date I'm using ASP.NET MVC and LINQ-to-SQL on a SQL Server database.

• Get data from database without refresh whole page

  - by stefanz

  Hello everybody. My project is about a school admin I have a page called : createClass.php, where user inserts grade, profile etc. When he press "submit" page called createdClass.php is loading. Inside this page I have all code which insert data into database and also an "if" structure which says : "Class already exists" if in database is another class with same specifications. Also in second page (createdClass.php) i have a small table which shows the place of each student. First time all cells are green (this means that place is free) and if i click one of them appear a popup window which let me to add info about student from that place. If a place is busy the cell will be red (take a look here : http://screencast.com/t/NzM2YzYxNjct). The big problem is that the cell will be red only after refresh the page (the place ask for data from database). If I press refresh appears "class already exists". To test the code i added in a comment all lines which verify and add respectively classroom . I think my problem can be solved with ajax. I'm waiting for an answer. Regards Stefan

• PHP - Database schema: version control, branching, migrations.

  - by Billiam

  I'm trying to come up with (or find) a reusable system for database schema versioning in php projects. There are a number of Rails-style migration projects available for php. http://code.google.com/p/mysql-php-migrations/ is a good example. It uses timestamps for migration files, which helps with conflicts between branches. General problem with this kind of system: When development branch A is checked out, and you want to check out branch B instead, B may have new migration files. This is fine, migrating to newer content is straight forward. If branch A has newer migration files, you would need to migrate downwards to the nearest shared patch. If branch A and B have significantly different code bases, you may have to migrate down even further. This may mean: Check out B, determine shared patch number, check out A, migrate downwards to this patch. This must be done from A since the actual applied patches are not available in B. Then, checkout branch B, and migrate to newest B patch. Reverse process again when going from B to A. Proposed system: When migrating upwards, instead of just storing the patch version, serialize the whole patch in database for later use, though I'd probably only need the down() method. When changing branches, compare patches that have been run to patches that are available in the destination branch. Determine nearest shared patch (or oldest difference, maybe) between db table of run patches and patches in destination branch by ID or hash. Could also look for new or missing patches that are buried under a number of shared patches between the two branches. Automatically merge down to the nearest shared patch, using the db table stored down() methods, and then merge up to the branche's latest patch. My question is: Is this system too crazy and/or fraught with consequences to bother developing? My experience with database schema versioning is limited to PHP autopatch, which is an up()-only system requiring filenames with sequential IDs.

• Using PHP to display button with hyperlink or greyed out button if no URL in database

  - by Diane

  I've got a webpage that I'm working on where you click on a letter or category and it displays records matching that query from a database. One of the things I want to display is a hyperlinked button that says "Website" if the database record contains a URL in the 'URL' field, and if there is no value in that field, it will display a greyed out version of that button. I tried using an if...else statement, but was absolutely unable to get the syntax correct trying to get php to call up the 'URL' value in the middle of an "echo " So here's what I did: <?php if($row_rsmemalpha['URL'] != NULL) ?><a href="http://<?php echo ($row_rsmemalpha['URL']);?>"><target ="_blank"><img src="web_button_on.gif" alt="Website" border="0" height="18" width="103" /></target></a> <?php if($row_rsmemalpha['URL'] == NULL) echo "<img src=\"web_button_off.gif\" alt=\"No Website Available\" height=\"18\" width=\"103\" />"; ?> If there is a URL available it shows the button properly. But if there isn't a URL in the database it shows both buttons. I have spent a few days studying examples and tutorials on the web, but haven't found too much that helps. The buttons were completely non-functional when I started, so I'm pretty proud of getting this far with it! I've just run out of time and patience for more trial-and-error experimenting. Any help is appreciated... Diane

• When optimizing database queries, what exactly is the relationship between number of queries and siz

  - by williamjones

  To optimize application speed, everyone always advises to minimize the number of queries an application makes to the database, consolidating them into fewer queries that retrieve more wherever possible. However, this also always comes with the caution that data transferred is still data transferred, and just because you are making fewer queries doesn't make the data transferred free. I'm in a situation where I can over-include on the query in order to cut down the number of queries, and simply remove the unwanted data in the application code. Is there any type of a rule of thumb on how much of a cost there is to each query, to know when to optimize number of queries versus size of queries? I've tried to Google for objective performance analysis data, but surprisingly haven't been able to find anything like that. Clearly this relationship will change for factors such as when the database grows in size, making this somewhat individualized, but surely this is not so individualized that a broad sense of the landscape can't be drawn out? I'm looking for general answers, but for what it's worth, I'm running an application on Heroku.com, which means Ruby on Rails with a Postgres database.

• Images in database vs file system

  - by Jesse

  We have a project coming up where we will be building a whole backend CMS system that will power our entire extranet and intranet with one package. The question I have been trying to find an answer to is which is better: storing images in the database (SQL Server 2005) so we may have integrity, single replication plan, etc OR storing on the file system? One issue we have is that we have multiple servers load balanced that require to have the same data at all times. As of now we have SQL replication taking care of that but file replication seems to be a little tougher. Another concern we have is that we would like to have multiple resolutions of the same image, we are not sure if creating and storing each version on the file system would be best or maybe dynamically pulling and creating the resolution image we would like upon request. Our concerns are the with the following: Data integrity Data replication Multiple resolutions Speed of database vs file system Overhead load of database vs file system Data management and backup Does anyone have a similar situation or have any input on what would be recommended? Thanks in advance for the help!

• MySQL database design question

  - by Greelmo

  I'm trying to weigh the pros and cons of a database design, and would like to get some feedback as to the best approach. Here is the situation: I have users of my system that have only a few required items (username, password). They can then supply a lot of optional information. This optional information continues to grow as the system grows, so I want to do it in such a way that adding new optional information is easy. Currently, I have a separate table for each piece of information. For example, there's a table called 'names' that holds 'user_id', 'first_name', and 'last_name'. There's 'address', 'occupation', etc. You get the drift. In most cases, when I talk to my database, I'm looking only for users with one particular qualifier (name, address, etc.). However, there are instances when I want to see what information a user has set. The 'edit account' page, for example, must run queries for each piece of information it wants. Is this wasteful? Is there a way I can structure my queries or my database to make it so I never have to do one query for each piece of information like that without getting my tables to huge? If i want to add 'marital status', how hard will that be if I don't have a one-table-per-attribute system? Thanks in advance.

• Entity Framework - refresh objects from database

  - by Nebo

  I'm having trouble with refreshing objects in my database. I have an two PC's and two applications. On the first PC, there's an application which communicates with my database and adds some data to Measurements table. On my other PC, there's an application which retrives the latest Measurement under a timer, so it should retrive measurements added by the application on my first PC too. The problem is it doesn't. On my application start, it caches all the data from database and never get new data added. I use Refresh() method which works well when I change any of the cached data, but it doesn't refresh newly added data. Here is my method which should update the data: public static Entities myEntities = new Entities(); public static Measurement GetLastMeasurement(int conditionId) { myEntities.Refresh(RefreshMode.StoreWins, myEntities.Measurements); return (from measurement in myEntities.Measurements where measurement.ConditionId == conditionId select measurement).OrderByDescending(cd => cd.Timestamp).First(); } P.S. Applications have different connection strings in app.config (different accounts for the same DB).

• PHP Database connection practice

  - by Phill Pafford

  I have a script that connects to multiple databases (Oracle, MySQL and MSSQL), each database connection might not be used each time the script runs but all could be used in a single script execution. My question is, "Is it better to connect to all the databases once in the beginning of the script even though all the connections might not be used. Or is it better to connect to them as needed, the only catch is that I would need to have the connection call in a loop (so the database connection would be new for X amount of times in the loop). Yeah Example Code #1: // Connections at the beginning of the script $dbh_oracle = connect2db(); $dbh_mysql = connect2db(); $dbh_mssql = connect2db(); for ($i=1; $i<=5; $i++) { // NOTE: might not use all the connections $rs = queryDb($query,$dbh_*); // $dbh can be any of the 3 connections } Yeah Example Code #2: // Connections in the loop for ($i=1; $i<=5; $i++) { // NOTE: Would use all the connections but connecting multiple times $dbh_oracle = connect2db(); $dbh_mysql = connect2db(); $dbh_mssql = connect2db(); $rs_oracle = queryDb($query,$dbh_oracle); $rs_mysql = queryDb($query,$dbh_mysql); $rs_mssql = queryDb($query,$dbh_mssql); } now I know you could use a persistent connection but would that be one connection open for each database in the loop as well? Like mysql_pconnect(), mssql_pconnect() and adodb for Oracle persistent connection method. I know that persistent connection can also be resource hogs and as I'm looking for best performance/practice.

• Database Functional Programming in Clojure

  - by Ralph

  "It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail." - Abraham Maslow I need to write a tool to dump a large hierarchical (SQL) database to XML. The hierarchy consists of a Person table with subsidiary Address, Phone, etc. tables. I have to dump thousands of rows, so I would like to do so incrementally and not keep the whole XML file in memory. I would like to isolate non-pure function code to a small portion of the application. I am thinking that this might be a good opportunity to explore FP and concurrency in Clojure. I can also show the benefits of immutable data and multi-core utilization to my skeptical co-workers. I'm not sure how the overall architecture of the application should be. I am thinking that I can use an impure function to retrieve the database rows and return a lazy sequence that can then be processed by a pure function that returns an XML fragment. For each Person row, I can create a Future and have several processed in parallel (the output order does not matter). As each Person is processed, the task will retrieve the appropriate rows from the Address, Phone, etc. tables and generate the nested XML. I can use a a generic function to process most of the tables, relying on database meta-data to get the column information, with special functions for the few tables that need custom processing. These functions could be listed in a map(table name -> function). Am I going about this in the right way? I can easily fall back to doing it in OO using Java, but that would be no fun. BTW, are there any good books on FP patterns or architecture? I have several good books on Clojure, Scala, and F#, but although each covers the language well, none look at the "big picture" of function programming design.

• How to get MySQL database to appear on index.php

  - by Teddy Truong

  Hi, I have a submission form on my website (index.php) and I have the data(user submissions) being stored into a MySQL database. Right now, I have the user submitting a post and then the page directs them to an update.php which shows what they inputed. However, I want all of the data in the database in MySQL to be shown on the index.php. It's a lot like a comment system. User submits a post... and sees their post above the other submitted posts all on the same page. I think I'm missing AJAX... ? Here is the code for index.php <div align="center"> <p>&nbsp;</p> <h2 align="center" class="Title"><em><strong>REDACTED</strong></em></h2> <form id="form1" name="form1" method="post" action="update.php"> <hr /> <label><br /> <form action="update.php" method="post"> REDACTED: <input type="text" name="text" /> <input type="submit" /> </form> </label> </form> </div> On update.php I have this: ?php $text = $_POST['text']; $myString = "REDACTED"; mysql_connect ("db----.net", "-----3", "------------") or die ('Error: ' . mysql_error()); mysql_select_db ("-----------"); $query="INSERT INTO TextArea (ID, text) VALUES ('NULL', '".$text."')"; mysql_query($query) or die ('Error updating database'); echo " $myString "," $text "; ?> Thanks a lot!

• Question regarding ideal database implementation for iPhone app

  - by Jeff

  So I have a question about the ideal setup for an app I am getting ready to build. The app is basically going to be a memorization tool and I already have an sqlite database full of content that I will be using for the app. The user will navigate through the contents of the database(using the uipickerview), and select something for memorization. If that row or cell of data is selected, it is put into a pool or a uitableview that is dedicated to showing which items you have in your "need to memorize" pool. When you go to that tableview, you can select the row, and the actual data would be populated. All information in the tableview would be deletable, in the event that they don't want it there anymore... Thats it. I know that with database interfacing, there are a few different options out there, in this particular setup, is core data the easiest approach? Is there any other way that would be better? I am just kind of looking for a point in the right direction, any help is greatly appreciated!!

• Database abstraction/adapters for ruby

  - by Stiivi

  What are the database abstractions/adapters you are using in Ruby? I am mainly interested in data oriented features, not in those with object mapping (like active record or data mapper). I am currently using Sequel. Are there any other options? I am mostly interested in: simple, clean and non-ambiguous API data selection (obviously), filtering and aggregation raw value selection without field mapping: SELECT col1, col2, col3 = [val1, val2, val3] not hash of { :col1 = val1 ...} API takes into account table schemas 'some_schema.some_table' in a consistent (and working) way; also reflection for this (get schema from table) database reflection: get list of table columns, their database storage types and perhaps adaptor's abstracted types table creation, deletion be able to work with other tables (insert, update) in a loop enumerating selection from another table without requiring to fetch all records from table being enumerated Purpose is to manipulate data with unknown structure at the time of writing code, which is the opposite to object mapping where structure or most of the structure is usually well known. I do not need the object mapping overhead. What are the options, including back-ends for object-mapping libraries?

• Database schema for Product Properties

  - by Chemosh

  As so many people I'm looking for a Products /Product Properties database schema. I'm using Ruby on Rails and (Thinking) Sphinx for faceted searches. Requirements: Adding new product types and their options should not require a change to the database schema Support faceted searches using Sphinx. Solutions I've come across: (See Bill Karwin's answer) Option 1: Single Table Inheritance Not an option really. The table would contain way to many columns. Option 2: Class Table Inheritance Ruby on Rails caches the database schema on start-up which means a restart whenever a new type of product is introduced. If you have a size able product catalog this could mean hundreds of tables. Option 3: Serialized LOB Kills being able to do faceted searches without heavy application logic. Option 4: Entity-Attribute-Value For testing purposes, EAV worked fine. However it could quickly become a mess and a maintenance hell as you add more and more options (e.g. when an option increase the prices or delivery time). What option should I go with? What other solutions are out there? Is there a silver bullet (ha) I overlooked?

• Flexible forms and supporting database structure

  - by sunwukung

  I have been tasked with creating an application that allows administrators to alter the content of the user input form (i.e. add arbitrary fields) - the contents of which get stored in a database. Think Modx/Wordpress/Expression Engine template variables. The approach I've been looking at is implementing concrete tables where the specification is consistent (i.e. user profiles, user content etc) and some generic field data tables (i.e. text, boolean) to store non-specific values. Forms (and model fields) would be generated by first querying the tables and retrieving the relevant columns - although I've yet to think about how I would setup validation. I've taken a look at this problem, and it seems to be indicating an EAV type approach - which, from my brief research - looks like it could be a greater burden than the blessings it's flexibility would bring. I've read a couple of posts here, however, which suggest this is a dangerous route: How to design a generic database whose layout may change over time? Dynamic Database Schema I'd appreciate some advice on this matter if anyone has some to give regards SWK

• Best practice how to store HTML in a database column

  - by tbrandao

  I have an application that modifies a table dynamically, think spreadsheet), then upon saving the form (which the table is part of) ,I store that changed table (with user modifications) in a database column named html_Spreadhseet,along with the rest of the form data. right now I'm just storing the html in a plain text format with basic escaping of characters... I'm aware that this could be stored as a separate file, the source table (html_workseeet) already is. But from a data handling perspective its easier to save the changed html table to and from a column so as to avoid having to come up with a file management strategy (which folder will this live in, now must include folder in backups, security issues now need to apply to files, how to sync db security with file system etc.), so to minimize these issues I'm only storing the ... part in the database column. My question is should I gzip the HTML , maybe use JSON, or some other format to easily store and retrieve the HTML from the database column, what is the best practice to store HTML content in a datbase? Or just store it as I currently am as an escaped text column?
