DataObjects.Net v4.0 is rapid database application development framework. It combines comprehensive business logic layer development framework, object-relational mapper and a set of storage implementations enabling the same BLL code work everywhere dramatically reducing the resources and time you need to develop generally any application dealing with persistent data.

Rapid development

DataObjects.Net is designed to allow you doing more with less code. DataObjects.Net accelerates development process by automatically mapping your entities to the relational data, providing complete LINQ implementation, automatically upgrading the schema on changes in Domain model and offering full-featured in-memory database for the client-side data and unit tests.

Reduced costs

The platform incorporates client-side database eliminating necessity to use SQL Server Compact or SQLite; synchronization and disconnected state containers replacing Sync Framework, .NET RIA Services and ADO.NET Data Services*. Full storage transparency allows you to migrate between proprietary (MS SQL, Oracle*) and open source (PostgreSQL, MySQL*) databases with no coding at all.

Excellent Performance

DataObjects.Net v4.0 was built anew from scratch and all the experience we've got during past 6 years of development of its predecessors is now a part of it. It is not just performs well: it is designed to beat the competitors. Check out our Tips blog for evidences, and DataObjects.Net performance article for facts.
