LLBLGen Pro, the #1 O/R mapper and data-access tier generator for .NET, generates a complete data-access tier and business facade/support tier for you (in C# or VB.NET), using an existing database schema set.

The generated .NET code is compiler-ready and can, being compiled by the .NET C# or VB.NET compiler, be used immediately by other applications.But that isn't all!

LLBLGen Pro does more for you, increasing productivity even further: you can create Typed Lists, which are lists of Entity fields (which are mapped on a table definition or view definition and support type inheritance) from a set of entities which have 1:1, 1:n or m:1 relations which each other.

It also lets you easily create Typed Views, which are 1:1 maps on existing views in your catalog / schema.

Furthermore, you don't lose investments in stored procedures, because LLBLGen Pro fully supports existing stored procedures by creating wrapper code, that lets you call a stored procedure with one line of code.

If that's not enough, you can always add the templates used to produce the generated code, or create your own, using our powerful Template Studio template editor (free for customers).LLBLGen Pro saves developers a lot of time, up to over 50% of a total project's development time, and lets them focus on the real deal: business logic code, instead of having them hammer out an endless list of almost the same routines.

You design your database schema's with the abstract modelling tools you always use (for example a NIAM/ORM designer like Visio, or an E/R modeller), and LLBLGen Pro takes care of the rest.

All you have to do next is modify some of the names LLBLGen Pro has given entities and fields if necessary, and generate code.LLBLGen Pro comes with a powerful, state-of-the-art user interface, which doesn't require an expensive IDE to run.
