detail
The data stored in the ADM database cannot be customized or manipulated for creating custom reports.
Therefore, ADM provides functionality for exporting the data into an ADM external repository, from which
custom reports are created.
The data transferred to the external repository is not real‐time data. It is synchronized at regular intervals as
defined in the External Reports Scheme Configuration policy.

Synchronizing the External Database

Figure 1‐2 illustrates how the ADM external database is synchronized with the ADM repository through the
ETL (Extract‐Transform‐Load) process. Extraction and transformation is done through ADM and loading is
done by the adm_olap component on the external database host.

Reporting Schema
The synchronization process comprises of the following steps:
1 The synchronization is triggered according to the settings in the External Reports Scheme Configuration
policy.
2 ADM checks the status of the replication to ensure that the previous synchronization and that any report
requests against the external database has completed.
3 ADM extracts the data files for the load process as follows:
a The Report Schema is extracted and translated to .csv files.
b The data files are compressed and placed together in a single Zip archive.
c The Zip file is uploaded to the assigned FTP server.
4 The system running the external database periodically checks the FTP server for data files based on the
synchronization schedule defined on the external database system.
