Several years ago, Erik Doernenburg created a type of ORM (Object-Relational Mapping) software named Neo.

From the original project:

The .NET Entity Objects Framework

Neo is a framework for .NET developers who want to write enterprise applications with an object-based domain model. It is well suited for domain-driven design and agile development.

Neo includes tools that create an extensible object-based domain model as well as the database schema from a an abstract description of the model. At run-time, rich schema information is used to dynamically generate all SQL required for object persistence management. Being based on ADO.NET data sets, a Neo domain model is independent of the actual backing store and works equally well with databases and objects in an XML representation.

The last official release was in June 2006. Since then, several users have continued to use and improve Neo. This project, dubbed Neo2, is our effort to consolidate, update, and extend this most excellent development tool.
