This section explains how to synchronize the logical model of a database (represented by a data diagram) with the corresponding physical (relational) model.

Although synchronization of the relational model from the data diagram essentially concerns entities, it can also be carried out more generally from classes of a class diagram.

Synchronization in the reverse direction, from a physical model to a logical model, is also possible but not on the same database. When synchronization direction has been selected for an object, synchronization in the other direction will no longer be possible.

See "From the Physical Model to the Logical Model".

The points that follow present synchronization of a database. You can also run reduced synchronization, in other words on a specific object of the database. See "Reduced Synchronization (Logical to physical mode)".
