With DevExpress XPO, you can build applications that work with multiple database systems (presently supports MS Access, MS SQL Server, MySQL, Oracle, PostgreSql, Firebird, PervasiveSQL, VistaDB, SQL Anywhere, Advantage, DB2 and Sybase) without making any changes to your code.

Easy to Use and Highly Productive

It will transparently handle relationships between classes and object inheritance. But you never sacrifice ease-of-use for flexibility. If you ever need more control over O/R mapping, you can simply use the built-in attributes to provide additional mapping...
