Tdo -Typed Data Object 2.0

Tdo is the acronym of Typed Data Object and ismade up of a NET assembly (Tdo.dll) and a source code generator(TdoCodeGenerator.exe). The source code generator produces a collectionof derived classes (VB.NET/C#.NET) that extends the base classes withinthe Tdo.dll assembly, all under the Object Oriented model.Every generated class has the scope "to represent" an object of yourSQL database, where object are Tables, Views, Stored Procedures,Functions. According to this model, every table or view, etc, isconsidered as an object itself that shows its attributes and operations(that are properties and methods).That means that the single cell of a table or the single parameter of astored procedure will be seen as object itself. All these classes areenclosed in a hierarchically macro-object as a representation of theentire database – the TdoHelper class.More ahead we'll see all the possible operations that we can execute onour database (select, insert, update, delete, stored procedure, etc)that will be called from the present methods within the TdoHelper classobjects.

Tdo Is Open Source

From this version (2.0), Tdo has become anopen source project and both the source code and the setup package aredownloadable from sourceforge.net at the following web address:http://tdo.sourceforge.net.The setup package installs both the base library Tdo.dll and the sourcecode generator TdoCodeGenerator.exe.To be able to use it it's recommended to have already installed both MSVisual Studio .NET 2005 and Sql Server 2005 (or EXPRESS/2000/7/MSDE).
