eXpress Persistent Objects for .NET completely abstracts the database layer from a developer, leaving him or her fully in the object-oriented realm. With XPO, you can build applications that work with multiple database systems (presently supports MS Access and MS SQL Server) without making ANY changes to your code.
Easy to Use and Highly Productive
So how easy is it to use? Extremely easy…With eXpress Persistent Objects for .NET, you never again have to deal with table mapping - all you need is to define persistent object classes, and XPO.NET will generate your database for them automatically. It will transparently handle relationships between classes and object inheritence. But you never sacrifice ease-of-use for flexibility. If you ever need more control over O/R mapping, you can simply use our built-in attributes to provide additional mapping information to XPO.NET and thus address any business requirement.
With XPO.NET, you can start your database application development directly from the object model. You never have to spend your time on tables, columns, keys and constraints - just roll up your sleeves and focus on writing code! XPO.NET will keep your database structure up-to-date. It will allow you to focus on important application-specific issues, rather than on pain-in-the-neck generic purpose database issues.
Like all Developer Express .NET technologies, XPO is available with full source code.
