HISTORY
DAD has few "business rules". The model is built by the users and its structure guides users to enter valid and consistent data. This approach allows diversity at the same time as it encourages consistency.
The DAD Administrator has the sole responsibility of assigning users' rights. These can be revised for any user at any time.
Every object in DAD has a history. This logs every user operation that has affected the object from creation to deletion.
These screenshots show some typical histories for various object types.
There are a range of utilities to handle the history data for the complete model.
