An ORM. Useful for prototyping but it has the ability to generate a database from a model, keeps them in sync, and has the ability to analyze the database and make suggestions. Has lazy loading, allows quering using IQueryables, straight SQL, and caching of data is built in. So in otherwords, it's a basic ORM.
