During the last few weeks I've had some time to kill so I decided to fill up our Knowledge Base with new material on eXpress Persistent Object (XPO). For me, this product can be thought of like an iceberg: At its surface, one sees only a small portion of what's hiding underneath. With XPO, you need to know very little about the product to create your first application. But by digging a bit deeper you'll uncover many new aspects of the product and hopefully appreciate its strengths and power, and feel even more confident to place it as the foundation of your data-aware applications.
So, enough with the metaphors...here are a few articles to help you dig deeper into XPO in many unique ways:
How to use XPO in an ASP.NET (Web) application
Getting started with XPO development for Compact devices
How to create a criterion, which returns an intersection of two many-to-many sets
How to implement self-referenced persistent objects, and to display these objects within the XtraTreeList
