• How do I load the Oracle schema into memory instead of the hard drive?

  - by Andrew

  I have a certain web application that makes upwards of ~100 updates to an Oracle database in succession. This can take anywhere from 3-5 minutes, which sometimes causes the webpage to time out. A re-design of the application is scheduled soon but someone told me that there is a way to configure a "loader file" which loads the schema into memory and runs the transactions there instead of on the hard drive, supposedly improving speed by several orders of magnitude. I have tried to research this "loader file" but all I can find is information about the SQL* bulk data loader. Does anyone know what he's talking about? Is this really possible and is it a feasible quick fix or should I just wait until the application is re-designed?

• Normalization in plain English

  - by Yada

  I sort of understand the concept of database normalization but always have a hard time explaining it in plain English especially for a job interview. I have read the wikipedia post, but still find it hard to explain the concept to none developers. "Design a database in a way not to get duplicated data" is the first thing that comes to mind. Does anyone was a nice way to explain the concept of database normalization in plain English. And what are some nice examples to show the differences between first, second and third normal forms. Say you go to a job interview and the person asks: Explain the concept of normalization and how would go about designing a normalized database. What key points are the interviewer looking for?

• What is a good Visio Enterprise Architect replacement?

  - by MattValerio

  I've been using Visio 2002/2003 Enterprise Architect to do my database schema design visually and then forward-generate the DDL to create the database. I wanted to switch to Visio 2007, but while it does have database diagramming support, it doesn't have the ability to generate DDL. Bummer. I am really disappointed because it seems like Microsoft has completely abandoned this feature. You can't do it in Visual Studio (that I've found). You can sorta do it with SQL Server Management Studio if you insert database diagrams into your database, but any edits to the schema immediately take effect. Has anyone found a good program to do this? I'm hoping to find one that is free and can generate DDL/SQL for SQL Server.

• Wiki Database, is there one?

  - by Faiz

  I was searching the net for something like a wiki database, just like wikipedia but instead stores structured content, editable by users. What I was looking for was an online database accessible by everyone where people can design the schema and data with proper versioning of both schema and data. I couldn't find any such site. I am not sure if it is my search skills or if there really is no wiki database as of now. Does anyone out there know anything like this? I think there is a great potential for something like this. A possible example will be a website with a GUI for querying a MySQL DB where any website visitor can create DB objects and populate data.

• Reverse engineer an ORM

  - by Oren Mazor

  Given a [mysql] database with a given schema, is it possible to generate an ORM interface for it? doesn't matter if its php, python or perl. in other words, I have a database and I have to ask it a few questions. while I could just craft a bunch of SQL queries (okay, several dozen), this is way more interesting to think about. is this a valid question, even? I have no design background with ORMs, but I've used a few (django's, symfony's, etc).

• How to reduce simple cpp application size? (compiled with RAD Studio 2010 cpp builder)

  - by peterg

  I am using rad studio 2010 cpp builder. I've created a new SDI application, added a TCppWebBrowser control and a simple button that onclick trigger the .navigate for the TCppWebBrowser, I compiled it and I got a 1.20mb file, I was expecting less than 700kb at least. How can I reduce the size of the compiled exe? I don't want to use "build with runtime packages", I know that will make it very small but I want to get all the necessary packages and dependencies inside the exe but maybe I am getting more than I use, I tried unchecking/removing a lot of design packages (in project/options/packages) I don't use but the file size didn't decreased. Also I was thinking maybe the TForm component that comes with RAD Studio is giving me more stuff than I need and that could make the file bigger, I mean I only need to drop a webbrowser control and a few buttons in the form, maybe there's a minimal form component I could use to replace TForm. Any suggestions will be appreciated.

• where to get a wordpress theme review

  - by Ayrton

  Hi I'm currently developing some Wordpress templates and I wanted to get a review by a (semi)professional. I already know quite a bit about Wordpress,CSS, & JS but I was always a lone wolf without any guidance that's why I was wondering where I could find someone (trustworthy) to do something like this and how much he should charge me. It's pure about the code (the PHP, JS & the CSS) I would like to have a review on about (nothing design related). A link to the Wordpress theme I'm talking about: http://demo.wpmonk.com Yours truthfully

• SubSonic: MySqlDataReader closes connection.

  - by SchlaWiener

  I am using SubSonic 2.1 and entcountered a problem while executing a Transaction with SharedDbConnectionScope and TransactionScope. The problem is that in the obj.Save() method I get an "The connection must be valid and open" exception I tracked down the problem to this line: // Loads a SubSonic ActiveRecord object User user = new User(User.Columns.Username, "John Doe"); in this Constructor of the User class a method "LoadParam" is called which eventually does if (rdr != null) rdr.Close(); It looks like the rdr.Close() implicitly closes my connection which is fine when using the AutomaticConnection. But during a transaction it is usally not a good idea to close the connection :-) My Question is if this is by design or if it's an error in the MySqlDataReader.

• How to achieve Bing maps like InfoWindow in Google Maps?

  - by BillB

  I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

• How should I manage data in an 2D vector based animation program?

  - by shadow

  I've been trying to design a program that makes 2D animations and then uses the ffmpeg library to create the video for possible use in tv and movies. The problem is when I think about how to manage the data in the application I can only think of two ways, I don't think either of them will work out very well. One is to use an SQlite database, but it seems like it will be difficult to save, especially if an artist puts 1000 things on screen. The other is to use something like linked lists, which would duplicate many features of the database and get complicated when dealing with things like points on a bezier curve and jumping to a frame and collecting all the objects that need to be drawn on that frame. Should I use one of these solutions, or is there something else that would be better? Currently planning to use C# for code.

• Asp.Net MVC 2 Client validation implementation for Enterprise Library Validation Block

  - by er-v

  Hello to everybody. I've found a very good article about how to use EntLib Validation Block for server validation in MVC 2. But as there pointed out The current design of EntLib’s Validation Application Block uses the Composite pattern; that is, when we ask for validation for an object, it returns back a single validator object that contains a list of all the validation work to be done. While this is very convenient from a normal usage scenario, the unfortunate side-effect is that we can’t “peek inside” to see what the individual validations are that it’s doing, and therefore can’t generate the appropriate client-side validation hints. So how is it possible to implement client side validation for EntLib? Is there work around?

• Algorithm for matching partially filled words

  - by adnanhb

  Hello All, I am writing a game which when given a partially filled word, searches a dictionary and returns all the matching words. To that effect, I am trying to find an algorithm that can be used for the said purpose. For example, given - - a -, the algorithm will search a dictionary for all the words which have length 4 and have 'a' as the third letter. Is there such an algorithm already? If not, can somebody given a rough idea of how to design such an algorithm? Thanks in Advance.

• Java, filling arrays, and inheritance

  - by Arvanem

  Hi folks, I think I'm running into an inheritance conceptual wall with my Java arrays. I'm kind of new to Java so please tell me if I have things upside down. In essence, I want to do three things: Create a runnersArray with the attributes of my Runners class. Fill my runnersArray using my GenerateObjects method of my GenerateObjects class. Access the contents of my filled runnersArray in my Evaluating method of my Evaluating class. The problem seems to be that runnersArray is not visible to the methods in steps 2 and 3 above, but their classes (due to design reasons) cannot inherit or extend Runners class. Thanks in advance for any suggestions. Here are some code snippets showing what I'm trying to do: public class Runners extends Party { Runners[] runnersArray = new Runners[5]; } and public class GenerateObject extends /* certain parent class */ { public GenerateObject (int arrayNum) { runnersArray[arrayNum] = /* certain Runners attributes */; } } and public class Evaluating extends /*certain parent class*/ { public Evaluating (int arrayNum) { System.out.println(/* String cast attribute of runnersArray[arrayNum]*/; } }

• Plugin Framework - can there be too many addin assemblies?

  - by spooner

  Hi, The product I'm working on needs to be built in such a way that we have a quote engine driven by a pluggable framework. We are currently thinking of using MAF, so we can leverage separation of the host and addin interfaces for versioning. However, I'm concerned that we'd have lots of assemblies, it's likely that we'd have one for each quote engine addin - of which there could be 100 going forward, we also need to support multiple versions, so there could be lots of assemblies in total. The quote engine also uses WF to drive it, which means each AppDomain for each addin will need a workflow runtime associated with it. This seems quite heavyweight, however we can unload unfrequently used addins. Does this seem like a good design? We've also looked at a single AppDomain solution using an IOC container to load addin types, but I'm concerned that we won't be able to unload any of the assemblies, given their quantity.

• PHP Tag Cloud System

  - by deniz

  Hi, I am implementing a tag cloud system based on this recommendation. (However, I am not using foreign keys) I am allowing up to 25 tags. My question is, how can I handle editing on the items? I have this item adding/editing page: Title: Description: Tags: (example data) computer, book, web, design If someone edits an item details, do I need to delete all the tags from Item2Tag table first, then add the new elements? For instance, someone changed the data to this: Tags: (example data) computer, book, web, newspaper Do I need to delete all the tags from Item2Tag table, and then add these elements? It seems inefficient, but I could find a more efficient way. The other problem is with this way is, if someone edits description but does not change the tags box, I still need to delete all the elements from Item2Tag table and add the same element. I am not an experienced PHP coder, so could you suggest a better way to handle this? (pure PHP/MySQL solution is preferable) Thanks in advance,

• Wrapping WPF UserControl inside VisualStudio Item Template

  - by karthik84

  I am currently started working on a project which will allow users to design reports inside visual studio. Previously, for my similar Winforms App, I had extended the IComponent (Component Class) and wrote our VS Like designer kind of custom control which will allow users to drag drop controls from the visual studio toolbox and then I export it as a VisualStudio C#&VB ItemTemplate. Now I am trying to recreate the same control using WPF considering its power, extensiblity. Could anyone shed some lights on this, on what would be the most preferable way of doing this ? Thanks in advance.

  Hi, I am new to NHibernate and need some information regarding the internal working of the engine: I have a table called Student and the design is as follows: RollNo Name City Postcode and there are 5 more columns like this. I have School class and mappings associated with it. I am querying RollNo and Name using session as given below: IQuery query = session.CreateQuery("SELECT RollNo,Name FROM Student); Executing query.List resulting in error because the query is returning object[][].

But, the results contain more data than I want. Could you please let me know the query to which I can get RollNo and Name from Student and castable as Student collection. Thanks, Mahesh

• what great software engineers know or aspiring ones should know?

  - by trojanwarrior3000

  I do not mean any particular language or methodology. But basics( one have abstracted from ones experience and interaction with smarter people in this field) one should have including concepts, practical issues, tips/techniques/tricks one should be aware of.For example the lessons or ideas may relate to programming,testing,design,project schedules, that are really useful in daily life of software engineer/developer etc ? This may be a good question because it looks not to specific, however experience of many is better than reading from books.I find discussions much helpful than books.Hope every one will have some lessons/ideas to contribute.please substantiate with atleast one example.

• what architecture for implementing a richtext editor?

  - by genesys

  Hi! Can someone give me some hints on how a clean implementation (designwise) of a richtext editor could look like that allows for things like setting fonts, setting character colors and so on? And when and how are characters rendered? are characters rendered only once and the bitmap representation is cached? Is there any article or book covering what software design would be appropriate for that? background is that we're working on a text editing software for a language that cannot be displayed with unicode any hint is appreciated! thanks!

• WPF: Create a dialog / prompt

  - by stefan.at.wpf

  Hello, I need to create a Dialog / Prompt including TextBox for user input. My problem is, how to get the text after having confirmed the dialog? Usually I would make a class for this which would save the text in a property. However I want do design the Dialog using XAML. So I would somehow have to extent the XAML Code to save the content of the TextBox in a property - but I guess that's not possible with pure XAML. What would be the best way to realize what I'd like to do? How to build a dialog which can be defined from XAML but can still somehow return the input? Thanks for any hint!

• Using Mapkit to create a local searchable Map

  - by Digital D

  Using MapKit as a base, I'm planning on adding a map to a project with 'local search' capabilities. I think 'local search' describes the feature I want to design into the map. Here is my vision. The map is displayed on the bottom half of a view. The user's current location is highlighted by default. When the user pushes the 'search' button annotation pins drop onto the map. The search is programmatically fixed to a certain item....for example supermarkets. So supermarkets in a 5 mile radius of the user's current location will populate the map. How would I add this local search feature to the already amazing MapKit? I've learned an incredible amount as a new developer in the last few months, and look forward to learning googles...correction googols more. Thanks in anticipation.

• .NET TCPListener limitation ?

  - by Karnalta

  Hi all, I have a question about the usage of TCPListener in .NET... I am thinking about a client/server application and being new to this kind of application I have search a bit around the web and the solution which come the more often is to create a new thread for each new client connection. This solution seem fine but I was wondering if it was still usable with a application where you can have thousands of client at the same time ? Of course if there is thousands of client the application will not be hosted on a small desktop but on a real server, but is it the way to design an application for a large number of client ? Thank for help.
