Overview

The following figure shows the Unified ICM databases and how changes made to the
Administration & Data Server local data are automatically applied to the central database.

Figure 8: The Unified ICME Databases

The Initialize Local Database tool copies data from the central database to the local database
(awdb). This tool is used to update the local database (awdb). Optionally, you can use this tool
to update the local database (awdb) at any time.

Note: Until the Initialize Local Database tool operation is completed, configuration changes
cannot be made.

Subsequently, the UpdateAW process forwards to the local database (awdb) any changes made
to the central database. Changes made to configuration data and scripts are automatically copied
from the central database back to the local database (awdb).

To make access to the real-time data as efficient as possible, the data are stored in memory in
temporary tables. These temporary tables actually reside in the TEMPDB database; however,
you can access them as if they were tables within the local database (awdb).

An Administration & Data Server that serves as an Historical Database Server (HDS) has a
special database to store historical data it receives from the central database. Administration
Clients can then access historical data from the HDS rather than from the central database.
