Over the views as on sets properties of related data objects, the following operations are possible:
- The Union operator
- The intersection operator &.
- The difference operator -.
- Excluding the Union, the ^ operator.
Associated submission of datalow are processed recursively.
Operations performance are a very convenient opportunity when performing a pochityvaya objects data services, data (for example, if a data object initialized with the part properties and want to display it in the view with a wider set of properties, you can calculate the difference and to read a data object only through it).
An example of working with operations on views is available at https://github.com/Flexberry/FlexberryORM-DemoApp/blob/master/FlexberryORM/CDLIB/CDADMTEST/Form1.cs.
