• How to return relationships in a custom un-typed dataservice provider

  - by monkey_p

  I have a custom .Net DataService and can't figure out how to return the data for relationships. The data base has 2 tables (Customer, Address). A Customer can have multiple addresses, but each address can only have on customer. I'm using Dictionary<string,object> as my data type. My question, for the following 2 urls how do i return the data. http://localhost/DataService/Customer(1)/Address http://localhost/DataService/Address(1)/Customer For the none relational queries I return a List<Dictionary<string,object>> So I imagined for the relation I should just populate the element with a either a Dictionary<string,object> for the single ones and a List<Dictionary<string,object>> for many relationships. But this just gives me a NullRefferenceException So what am I doing wrong?

• ADO.NET DataService Exception

  - by Ravi

  Hi, I am working on C#.Net with ADO.NET Dataservice. I try to update one record to relational tabel, when I reach context.SetLink() I am getting exception("The context is not currently tracking the entity"). I don't know how to solve this problem. My code is specified below. LogNote dbLogNote =logNote; LogSubSession dbLogSubSession = (from p in context.LogSubSession where p.UID == logNote.SubSessionId select p).First<LogSubSession>() as LogSubSession; context.AddToLogNote(dbLogNote); dbLogNote.LogSubSession = dbLogSubSession; context.SetLink(dbLogNote, "LogSubSession", dbLogSubSession); context.SaveChanges(); Here LogSubSession is a primary table and LogNote is a foreign table. I am updating data into foreign table based on primary key table. Thanks

• How do I take the advantage of the variable column key/value structure of Cassandra

  - by icejade

  If I have to predefine all the columns, how do I take the advantage of the variable column key/value structure of cassandra? If I use update table command, it will insert null for all the rows which don't have that column. This is same as relational DB. For example, for contact column family, I have name, phone, email. I have 100 contacts have all 3 field. Then number 101 contact has skype id which I want to add. If I use insert statement, it won't let me add skypeid since it's not defined in the CF. So I have to run alter statement to change the CF, then all the first 100 contacts will have a null field for each of them.

• Understanding NoSQL Data Modeling - blog application

  - by Rushabh RajeshKumar Padalia

  I am creating an blogging application in Node.js + MongoDB Database. I have used relational Database like MySQL before but this is my first experience with NoSQL database. So I would like to conform my MongoDB data models before I move further. I have decided my blogDB to have 3 collections post_collection - stores information about that article comment_collection - store information about comments on articles user_info_collection - contains user inforamtion PostDB { _"id" : ObjectID(...), "author": "author_name", "Date": new Date(....), "tag" : ["politics" , "war"], "post_title": "My first Article", "post_content": "Big big article" "likes": 23 "access": "public" } CommentDB { "_id" : Objectid(...), "POST": "My First Article", "comment_by": "User_name", "comment": "MY comments" } UserInfoDB { "_id": ObjectID(...), "user": "User_name", "password": "My_password" } I would appreciate your comments.

• A better understanding of the relations beetween database tables

  - by Nistor Alexandru

  Hi I am trying to get a better understanding of relational databases and there is something that I keep bumping into and don't understand.Let's take this two tables: In this case Login.ID is the primary key with auto_increment set and Profile.ID_LOGIN is the Foreign KEY.When a user is created and it's username and password is stored in the login database does the ID coresponding to the curesnt username and password get automaticly added into ID_LOGIN or do I have to create an SQL statement to do this? If I have to create a SQL statement how should I aproach adding the ID_LOGIN to make sure I am adding it corectly?

• Is there a tool that will show diagrams of my SQL database in real-time?

  - by Rising Star

  I've created some diagrams of SQL tables using the "Reverse Engineer" feature of Microsoft Office Visio. I like being able to visualize my relational databases in this manner. However, what I get is just a static document that I can print, e-mail to colleagues, and click widgets on. Earlier this year, I saw at a demo that the new version of Visual Studio 2010 has a new feature called the "Architect Explorer", which allows developers to view relationships among .net classes on the fly. It has many features for filtering the data that the developer is interested in. It would be really awesome if I could visually browse my tables and stored procedures and see what is related to what by primary key, foreign key, and referenced in stored procedures. I realize that I'm talking about two entirely different technologies and it's not a perfect analogy, but is there some similar tool that would allow me to visualize tables in my SQL database?

• Sphinx without using an auto_increment id

  - by squeeks

  I am current in planning on creating a big database (2+ million rows) with a variety of data from separate sources. I would like to avoid structuring the database around auto_increment ids to help prevent against sync issues with replication, and also because each item inserted will have a alphanumeric product code that is guaranteed to be unique - it seems to me more sense to use that instead. I am looking at a search engine to index this database with Sphinx looking rather appealing due to its design around indexing relational databases. However, looking at various tutorials and documentation seems to show database designs being dependent on an auto_increment field in one form or another and a rather bold statement in the documentation saying that document ids must be 32/64bit integers only or things break. Is there a way to have a database indexed by Sphinx without auto_increment fields as the id?

• FastObjects.NET(is an OODB from Versant) performence in Real Scenerios?

  - by Lalit

  FastObjects.NET Saves the whole class object(if marked with attribute Persistent) at once in file system(using serilization or similar technology). They are promissing that it is even faster then normal SQL DB approach. My team also thought it is better and faster to save the whole object once instead of each field one by one. Defination of their website: FastObjects .NET 10.0 fully conforms to the Microsoft.NET 2.0 framework. Tightly integrated with Visual Studio 2005, it offers a developer-friendly, object-oriented alternative to a relational database for .NET persistence. I want to have your experiences of using FastObjects in production scenerio? They are promising for Indexing/Transaction/clustoring/replication.

• A step-up from TiddlyWiki that is still 100% portable?

  - by Smandoli

  TiddlyWiki is a great idea, brilliantly implemented. I'm using it as a portable personal "knowledge manager," and these are the prize virtues: It travels on my USB flash memory stick and runs on any computer, regardless of operating system No software installation is needed on the computer (TiddlyWiki merely uses the Internet browser) No Internet connection is needed In terms of data retrieval functionality, it mimics a relational database (use of tags and internal links) Let's say I've got a million words of prose in 4,000 tiddlers (posts). I'm still testing, but it looks like TiddlyWiki gets very slow. Is there an app like TiddlyWiki that keeps all the virtues I listed above, and allows more storage? NOTE: Separation of content and presentation would be ideal. It's nifty that TiddlyWiki has everything in a single HTML document, but it's unhelpful in many ways. I don't care if a directory of assorted docs is needed (SQLite, XML?), as long as it's functionally self-contained.

• Why Your ERP System Isn't Ready for the Next Evolution of the Enterprise

  - by ken.pulverman

    ERP has been the backbone of enterprise software.  The data held in your ERP system is core of most companies.  Efficiencies gained through the accounting and resource allocation through ERP software have literally saved companies trillions of dollars. Not only does everything seem to be fine with your ERP system, you haven't had to touch it in years.  Why aren't you ready for what comes next? Well judging by the growth rates in the space (Oracle posted only a 3% growth rate, while SAP showed a 12% decline) there hasn't been much modernization going on, just a little replacement activity. If you are like most companies, your ERP system is connected to a proprietary middleware solution that only effectively talks with a handful of other systems you might have acquired from the same vendor.   Connecting your legacy system through proprietary middleware is expensive and brittle and if you are like most companies, you were only willing to pay an SI so much before you said "enough."  So your ERP is working.  It's humming along.  You might not be able to get Order to Promise information when you take orders in your call center, but there are work arounds that work just fine. So what's the problem? The problem is that you built your business around your ERP core, and now there is such pressure to innovate your business processes to keep up that you need a whole new slew of modern apps and you need ERP data to be accessible from everywhere.   Every time you change a sales territory or a comp plan or change a benefits provider your ERP system, literally the economic brain of your business, needs to know what's going on.  And this giant need to access and provide information to your ERP is only growing. What makes matters even more challenging is that apps today come in every flavor under the Sun™.   SaaS, cloud, managed, hybrid, outsourced, composite....and they all have different integration protocols. The only easy way to get ahead of all this is to modernize the way you connect and run your applications.  Unlike the middleware solutions of yesteryear, modern middleware is effectively the operating system of the enterprise.  In the same way that you rely on Apple, Microsoft, and Google to find a video driver for your 23" monitor or to ensure the Word or Keynote runs, modern middleware takes care of intra-application connectivity and process execution.  It effectively allows you to take ERP out of the middle while ensuring connectivity to your vital data for anything you want to do.  The diagram below reflects that change.    In this model, the hegemony of ERP is over.  It too has to become a stealthy modern app to help you quickly adapt to business changes while managing vital information.  And through modern middleware it will connect to everything.  So yes ERP as we've know it is dead, but long live ERP as a connected application member of the modern enterprise.

• Where are the real risks in network security?

  - by Barry Brown

  Anytime a username/password authentication is used, the common wisdom is to protect the transport of that data using encryption (SSL, HTTPS, etc). But that leaves the end points potentially vulnerable. Realistically, which is at greater risk of intrusion? Transport layer: Compromised via wireless packet sniffing, malicious wiretapping, etc. Transport devices: Risks include ISPs and Internet backbone operators sniffing data. End-user device: Vulnerable to spyware, key loggers, shoulder surfing, and so forth. Remote server: Many uncontrollable vulnerabilities including malicious operators, break-ins resulting in stolen data, physically heisting servers, backups kept in insecure places, and much more. My gut reaction is that although the transport layer is relatively easy to protect via SSL, the risks in the other areas are much, much greater, especially at the end points. For example, at home my computer connects directly to my router; from there it goes straight to my ISPs routers and onto the Internet. I would estimate the risks at the transport level (both software and hardware) at low to non-existant. But what security does the server I'm connected to have? Have they been hacked into? Is the operator collecting usernames and passwords, knowing that most people use the same information at other websites? Likewise, has my computer been compromised by malware? Those seem like much greater risks. What do you think?

• Case Insensitive Ternary Search Tree

  - by Yan Cheng CHEOK

  I had been using Ternary Search Tree for a while, as the data structure to implement a auto complete drop down combo box. Which means, when user type "fo", the drop down combo box will display foo food football The problem is, my current used of Ternary Search Tree is case sensitive. My implementation is as follow. It had been used by real world for around 1++ yeas. Hence, I consider it as quite reliable. My Ternary Search Tree code However, I am looking for a case insensitive Ternary Search Tree, which means, when I type "fo", the drop down combo box will show me foO Food fooTBall Here are some key interface for TST, where I hope the new case insentive TST may have similar interface too. /** * Stores value in the TernarySearchTree. The value may be retrieved using key. * @param key A string that indexes the object to be stored. * @param value The object to be stored in the tree. */ public void put(String key, E value) { getOrCreateNode(key).data = value; } /** * Retrieve the object indexed by key. * @param key A String index. * @return Object The object retrieved from the TernarySearchTree. */ public E get(String key) { TSTNode<E> node = getNode(key); if(node==null) return null; return node.data; } An example of usage is as follow. TSTSearchEngine is using TernarySearchTree as the core backbone. Example usage of Ternary Search Tree // There is stock named microsoft and MICROChip inside stocks ArrayList. TSTSearchEngine<Stock> engine = TSTSearchEngine<Stock>(stocks); // I wish it would return microsoft and MICROCHIP. Currently, it just return microsoft. List<Stock> results = engine.searchAll("micro");

• Are there any NOSQL-compatible CMS projects?

  - by Michael

  This question is partially related to an older question (Any CMS is Google App Engine compatible?) , but is slightly more general. It seems that in most CMS systems, the most fragile failure point is the database. Traditional database implementations scale poorly and will never be able to handle unforeseen spikes of traffic. Since Google App Engine was designed to help even small businesses overcome that problem, I had the same question that was asked earlier this year with less than satisfactory answers. But more generally, where are the CMS projects that support NOSQL databases? Looking over Wikipedia's list of CMS platforms, I see without much effort that only traditional RDBMS are supported by every single vendor on the list. I would have expected to see at least one or two projects handling CouchDB or similar engines. I understand the complexities of implementing a NOSQL solution to a problem that is typically solved using the relations cleanly expressed in any RDBMS, but there seems to be a rather wide market gap. Since databases are, today, easily outsourced to Google, Amazon, and others which use NOSQL models, I am amazed that there are not more projects actively pursuing this path. Am I simply not aware? Can someone please point me to projects that have real momentum that are developing on this path? I'm looking for two things: a CMS that has as its backbone a NOSQL database enabling easy database outsourcing (hosted MySQL clusters and similar solutions are not what I'm looking for) a project that is built to run on either a PaaS architecture like Google App Engine or an IaaS architecture like Amazon EC2 Any pointers in that direction would be most welcome.

• Easy way to "organize"/"render"/"generate" HTML?

  - by Rockmaninoff

  Hi all, I'm a relative newbie to web development. I know my HTML and CSS, and am getting involved with Ruby on Rails for some other projects, which has been daunting but very rewarding. Basically I'm wondering if there's a language/backbone/program/solution to eliminate the copypasta trivialities of HTML, with some caveats. Currently my website is hosted on a school server and unfortunately can't use Rails. Being a newbie I also don't really know what other technologies are available to me (or even what those technologies might be). I'm essentially looking for a way to auto-insert all of my header/sidebar/footer/menu information, and when those need to be updated, the rest of the pages get updated. Right now, I have a sidebar that is a tree of all of the pages on my website. When I add a page, not only do I need to update the sidebar, I have to update it for every page in my domain. This is really inefficient and I'm wondering if there is a better way. I imagine this is a pretty widespread problem, but searching Google turns up too many irrelevant links (design template websites, tutorials, etc.). I'd appreciate any help. Oh, and I've heard of HAML as a way to render HTML; how would it be used in this situation?

• checking mongo database for data

  - by user1647484

  I'm playing around with this tutorial that uses Sinatra, backbone.js, and mongodb for the database. It's my first time using mongo. As far as I understand it the app uses both local storage and a database. it has these routes for the database. For example, it has these routes get '/api/:thing' do DB.collection(params[:thing]).find.to_a.map{|t| from_bson_id(t)}.to_json end get '/api/:thing/:id' do from_bson_id(DB.collection(params[:thing]).find_one(to_bson_id(params[:id]))).to_json end post '/api/:thing' do oid = DB.collection(params[:thing]).insert(JSON.parse(request.body.read.to_s)) "{\"_id\": \"#{oid.to_s}\"}" end After turning the server off and then on, I could see in the server getting data from the database routes 127.0.0.1 - - [17/Sep/2012 08:21:58] "GET /api/todos HTTP/1.1" 200 430 0.0033 My question is, how can I check from within the mongo shell whether the data's in the database? I started the mongo shell ./bin/mongo I selected the database 'use mydb' and then looking at the docs (http://www.mongodb.org/display/DOCS/Tutorial) I tried commands such as > var cursor = db.things.find(); > while (cursor.hasNext()) printjson(cursor.next()); but they didn't return anything.

• Moving Javascript object with all bounded events to other variable

  - by Saif Bechan

  Let's say I have an anchor tag, with some events. <a id="clickme" href="/endpoint">clickme</a> <a id="clickme2" href="/endpoint2">clickme2</a> Let's use jquery for simplicity: $('#clickme').on('click', function(){.....}) I also have a variable: var myActiveVar = $('#clickme'); When I want to remove the element an every trace of it I can do this: myActiveVar.off().remove(); Here comes the problem, I want to reuse the variable. Something like this: var oldAcriveVar = myActiveVar; myActiveVar = $('#clickme2'); // Now I want to do some operations // both of the elements are still on // the page, when I'm done: oldActiveVar.off().remove(); Comeplete code: var myActiveVar = $('#clickme'); // Operate on myActiveVar var oldAcriveVar = myActiveVar; myActiveVar = $('#clickme2'); // Operate on myActiveVar which is // the new element. // Old element stays visible oldActiveVar.off().remove(); // Old element and all traces are gone Edit: Maybe the above code will work, but my problem goes beyond. I just gave a simplified example. I am using Backbone events that are bounded to object. They need to be removed when I am done with the object.

• Can't authenticate mobile client with node.js (using passport.js)

  - by Pazinio

  I'm trying to build some CRUD application with node.js as a back-end API (express) and web-app (backbone) and mobile client (native android) as front-ends.(I'm node.js beginner) My server solution is based on the following great tutorial 'easy-node-authentication'. In my android app I have managed to get the user Google-Token after I completed the authentication step with Google Plus SDK.(mobile to google-plus directly request). I'm trying to understand and find right and elegant way to re-use a given google-token and authenticate again my android user through Google-Plus account to ensure the mobile client holds real token, then add a new entry (id, token, email, name) to my users table DB within my node back-end. The question is: what should be my next step in case I want to keep my back-end without changes? should I send a GET request with the token as a cookie to /auth/google? maybe to /auth/google/callback? another URL? Does this make sense at all? Please note: I'm aware to the fact the mentioned above 'easy-node-auth' solution is based on sessions and cookies. having said that, i'm still trying to understand if there is a convenient way to integrate both (android and node) as it works good for my web-app and node. Thanks in advance.

• Some ASP.NET and Access

  - by Fazleh

  Good Day all, I have a big problem but i think its minor for you guys in Stackoverflow. I am creating a web application that has two main parts. The Payment part and Requisition part. It backbone is using access and the script is in ASP.NET. I managed to sort out most of the application. But I have been having a few problems. I have pasted the link to the project in http://www.mediafire.com/download/p09fefreifidud3/Inyatsi.rar so it will be easy for someone to see what I am blabbing about. Now for my problems: The AddRequisition.aspx/AddPayment.aspx: both have a reference number. I wanted it to be unique number(but not a primary key). I wanted it to be in the following format: DDMMYY(TransactionNo)(UserID) eg: 24061101PK. I have tried and tried but have not been able to sort it out. The AmountINWords gets the value from Amount. It converts the Amount into words. Thats not all. It picks what currncy was picked in the CurrencyPaidIn and pust the respective currency inside. eg. 123.45 USD becomes One Hundred and twenty three dollars and forty five cents. I tried using queries but as you will see that went all wrong. Those are the only two things that I cant seem to get my head around. I do know that there are some things that are not conventional ASP.NET and some text boxes are not the right size. I was thinking of sorting out those after I get those two fixed because they are simple to do. I really need some help with this application please. If someone can just have a look at the code and add a few things here and there. Thanks in advance. Faz

• Using linked servers, OPENROWSET and OPENQUERY

  - by BuckWoody

  SQL Server has a few mechanisms to reach out to another server (even another server type) and query data from within a Transact-SQL statement. Among them are a set of stored credentials and information (called a Linked Server), a statement that uses a linked server called called OPENQUERY, another called OPENROWSET, and one called OPENDATASOURCE. This post isn’t about those particular functions or statements – hit the links for more if you’re new to those topics. I’m actually more concerned about where I see these used than the particular method. In many cases, a Linked server isn’t another Relational Database Management System (RDMBS) like Oracle or DB2 (which is possible with a linked server), but another SQL Server. My concern is that linked servers are the new Data Transformation Services (DTS) from SQL Server 2000 – something that was designed for one purpose but which is being morphed into something much more. In the case of DTS, most of us turned that feature into a full-fledged job system. What was designed as a simple data import and export system has been pressed into service doing logic, routing and timing. And of course we all know how painful it was to move off of a complex DTS system onto SQL Server Integration Services. In the case of linked servers, what should be used as a method of running a simple query or two on another server where you have occasional connection or need a quick import of a small data set is morphing into a full federation strategy. In some cases I’ve seen a complex web of linked servers, and when credentials, names or anything else changes there are huge problems. Now don’t get me wrong – linked servers and other forms of distributing queries is a fantastic set of tools that we have to move data around. I’m just saying that when you start having lots of workarounds and when things get really complicated, you might want to step back a little and ask if there’s a better way. Are you able to tolerate some latency? Perhaps you’re able to use Service Broker. Would you like to be platform-independent on the data source? Perhaps a middle-tier might make more sense, abstracting the queries there and sending them to the proper server. Designed properly, I’ve seen these systems scale further and be more resilient than loading up on linked servers. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• SQLAuthority News – Book Review – Beginning T-SQL 2008 by Kathi Kellenberger

  - by pinaldave

  Beginning T-SQL 2008 by Kathi Kellenberger Amazon Link Detail Review: Beginning T-SQL 2008 is one of the best books on the market if you are just beginning to work with Microsoft SQL, or have a little bit of experience and need to learn more quickly. Each chapter of the book introduces a new subject, and builds upon topics covered in previous chapters.  The author of the book, Kathi Kellenberger understands that you need to form a solid foundation of knowledge before moving on to new topics, and sets up each subject nicely.  Because the chapters move in an orderly progression, you continue to use skills you learned earlier. One of the best features of Beginning T-SQL 2008 is that each chapter has multiple examples and exercises.  Many books introduce a topic and then never go back to it.  This book gives enough examples that you will be familiar with the subject when you come across it in real life.  The exercises at the end of the chapter mean that you will be using the skills you learned – and there is no better way to cement a subject in your brain. The book also includes discussions of the common errors that programmers will come across, how to avoid them, and how to fix them if they happen.  Ms. Kellenberger understands that not only do mistakes happen, but they are bound to happen if you aren’t trained properly.  Mistakes are part of the learning process! The book begins by discussions relational theory, so that programmers will understand the way T-SQL works from the ground up.  It also walks readers through writing accurate queries, combining set-based and procedural processing, embedding logic in stored functions, and so much more. Overall, the main goal of Beginning T-SQL 2008 is to introduce novices to SQL programming, and quickly familiarize them with the basics of running the program.  The book is written with the idea that readers will not know any of the technical terms or vocabulary.  However, if you are a little more familiar with SQL and looking to become better, you will still find this book very helpful. Ratting: 4.5+ Stars Summary: I must recommend Beginning T-SQL 2008 highly enough.  If you are going to buy any beginners guide to Transect-SQL, this is the one you should spend your money on.  You can save yourself a lot of time and effort later by using this very affordable manual to learn the basics, which will allow you to become an expert much faster.

• A few things I learned regarding Azure billing policies

  - by Vincent Grondin

  An hour of small computing time: 0,12$ per hour A Gig of storage in the cloud: 0,15$ per hour 1 Gig of relational database using Azure SQL: 9,99$  per month A Visual Studio Professional with MSDN Premium account: 2500$ per year Winning an MSDN Professional account that comes preloaded with 750 free hours of Azure per month:  PRICELESS !!!      But was it really free???? Hmmm… Let’s see.....   Here's a few things I learned regarding Azure billing policies when I attended a promotional training at Microsoft last week...   1)  An instance deployed in the cloud really means whatever you upload in there... it doesn't matter if it's in STAGING OR PRODUCTION!!!!   Your MSDN account comes with 750 free hours of small computing time per month which should be enough hours per month for one instance of one application deployed in the cloud...  So we're cool, the application you run in the cloud doesn't cost you a penny....  BUT the one that's in staging is still consuming time!!!   So if you don’t want to end up having to pay 42$ at the end of the month on your credit card like this happened to a friend of mine, DELETE them staging applications once you’ve put them in production! This also applies to the instance count you can modify in the configuration file… So stop and think before you decide you want to spawn 50 of those hello world apps  .     2) If you have an MSDN account, then you have the promotional 750 hours of Azure credits per month and can use the Azure credits to explore the Cloud! But be aware, this promotion ends in 8 months (maybe more like 7 now) and then you will most likely go back to the standard 250 hours of Azure credits. If you do not delete your applications by then, you’ll get billed for the extra hours, believe me…   There is a switch that you can toggle and which will STOP your automatic enrollment after the promotion and prevent you from renewing the Azure Account automatically. Yes the default setting is to automatically renew your account and remember, you entered your credit card information in the registration process so, yes, you WILL be billed…  Go disable that ASAP    Log into your account, go to “Windows Azure Platform” then click the “Subscriptions” tab and on the right side, you’ll see a drop down with different “Actions” into it… Choose “Opt out of auto renew” and, NOW you’re safe…   Still, this is a great offer by Microsoft and I think everyone that has a chance should play a bit with Azure to get to know this technology a bit more...     Happy Cloud Computing All

• LLBLGen Pro feature highlights: model views

  - by FransBouma

  (This post is part of a series of posts about features of the LLBLGen Pro system) To be able to work with large(r) models, it's key you can view subsets of these models so you can have a better, more focused look at them. For example because you want to display how a subset of entities relate to one another in a different way than the list of entities. LLBLGen Pro offers this in the form of Model Views. Model Views are views on parts of the entity model of a project, and the subsets are displayed in a graphical way. Additionally, one can add documentation to a Model View. As Model Views are displaying parts of the model in a graphical way, they're easier to explain to people who aren't familiar with entity models, e.g. the stakeholders you're interviewing for your project. The documentation can then be used to communicate specifics of the elements on the model view to the developers who have to write the actual code. Below I've included an example. It's a model view on a subset of the entities of AdventureWorks. It displays several entities, their relationships (both relational and inheritance relationships) and also some specifics gathered from the interview with the stakeholder. As the information is inside the actual project the developer will work with, the information doesn't have to be converted back/from e.g .word documents or other intermediate formats, it's the same project. This makes sure there are less errors / misunderstandings. (of course you can hide the docked documentation pane or dock it to another corner). The Model View can contain entities which are placed in different groups. This makes it ideal to group entities together for close examination even though they're stored in different groups. The Model View is a first-class citizen of the code-generator. This means you can write templates which consume Model Views and generate code accordingly. E.g. you can write a template which generates a service per Model View and exposes the entities in the Model View as a single entity graph, fetched through a method. (This template isn't included in the LLBLGen Pro package, but it's easy to write it up yourself with the built-in template editor). Viewing an entity model in different ways is key to fully understand the entity model and Model Views help with that.

This release is aligned with the new Oracle JDeveloper 11.1.2.3 version that we released today. Oracle ADF Essentials enables developers to use the following free: Oracle ADF Faces Rich Client components –over 150 JSF 2.0 components that include extensive charting and data visualization components, supports skinning, internalization, accessibility and touch gestures and providing advanced Ajax, windowing, drag and drop and other UI capabilities in a declarative way. Oracle ADF Controller – an extension on top of the JSF controller providing complete process flow definition and enabling advanced reusability of flows inside page’s regions. Oracle ADF Binding – a declarative way to bind various business services to JSF user interfaces eliminating tedious managed-beans coding. Oracle ADF Business Components – a declarative layer for building Java based business services on top of relational databases. The main goal of Oracle ADF Essentials is to bring the benefits of Oracle ADF to a broader community of developers. If you are already using Oracle ADF, a key new functionality for you would be the ability to deploy your application on GlassFish. Several other interesting points: We provide instructions for deployment of Oracle ADF Essentials on GlassFish and officially support this platform for Oracle ADF Essentials deployment. Developers can choose to use the whole Oracle ADF Essentials, or just pieces of the technology. Visual development for Oracle ADF Essentials is provided in Oracle JDeveloper. Eclipse support via Oracle Enterprise for Eclipse (OEPE) is also planned. Want to learn more? Here is a quick overview and development demo of Oracle ADF Essentials For more visit the Oracle ADF Essentials page on OTN
