Data Abstract is a multi-tier data access technology that provides full LINQ support directly on the client. Use Data Abstract's IDE-integrated tools to create strongly typed classes for the tables defined in your schemas. Then write natural code that queries and works with these types right in your client application. Behind the scenes, Data Abstract will convert your LINQ requests into DA SQL to perform the necessary queries on the middle-tier server - all secure and without bypassing business rules or access restrictions encoded in the server.
