DataObjects.Net is the ideal object-relational mapper (ORM) and business logic layer (BLL) development framework for modern .NET projects that:
- Wish to leverage all the best language features and technologies that .NET has to offer
- Have non-trivial domain models with deep inheritance and composite objects
- Prefer code-first, test-driven development
- Cannot settle for less than excellent performance
- Want a solution that scales easily
