Frequently Asked Questions

PassionORM® is an Enterprise level .Net ORM engine that converts data between incompatible data type systems in a relational database, and object-oriented programming languages like VB.Net and C#.

This creates, in effect, “a virtual object database” that can be used from within your code. The principle behind is to delegate to PassionORM® the management of persistence, and work at code-level with the objects representing a domain model, and not with the data structures in the same format as a relational database.

PassionORM® establishes a bi-directional link with the data in a relational database and the objects in code, based on a configuration and by executing dynamic SQL queries on the database. Linking business applications correctly with their Data should no longer be a tedious task.

For now, PassionORM (fully) supports development using C# and VB.NET.

You can generate a DAL layer in C# or VB.NET (as a standalone dll) and program against this dll in Delphi.NET (for instance). In other words, one can program partial classes (a.k.a events/extension methods) in C# or VB.NET only; the rest can be done in any language.

Within your code you add a ".dbgen" file and setup the connection string to your database. Now you can immediately program against your database. You can update your database at any moment and to let your code pick up on those changes you only have to re-compile your code.
