Refreshing your base model will synchronize it with the current
state of the database catalog. However, synchronizing the base model with
the catalog does not automatically incorporate differences between the catalog
and base model into the target model.
Important: Always check that the base model is in
synch with the catalog before you deploy your changes. The database might
have been changed between the time that you created your change commands and
the time that you want to deploy those change commands.
The option
to
Check if the base model has changed is selected
by default in the
Deploy Change Commands wizard. You
should not clear this check box unless you know that the base model and catalog
are in synch.
If you update the base without forward fitting the changes
into the target model, you run the risk of overwriting other changes.
Tip: After you refresh the base model, return to the Data
Models page and click Compare Base and Target Models.
Forward fit any changes from the base model into the target model.
To
refresh the base model of your database, complete the following steps:
A status bar is displayed that indicates the progress of the refresh
process.
Your base model now matches the most current state of the database
catalog. If there is a difference with the previous base model, regenerate
your change commands.
For more information on what to do if the base model
is out of synch with the database catalog see the Common
Problems topic.
