Data Manipulation and Business Logic
In XAF applications, you do not need to query data directly or via an ORM-specific context. Instead, XAF provides you with a convenient and powerful API independent from particular ORM and DBMS specifics – Object Space. Topics in this section familiarize you with the Object Space concepts – they describe how you can manipulate data and implement business logic.
