Entity Field

Set Key button

Any entity should have a key. Key could be single field or multi field.

Single field key should have name "Id" and it cannot be changed (this doesn't concern database name (Data Mapping - Name), it could have any name).

In multi field case fields could have any names.

Changes in Database section would not be transfered to database. See Code Cruiser Development Cycle for details.
