An OLAP Metadata Catalog is a database that consists of 33 tables in which DB2 OLAP Integration Server stores OLAP models and metaoutlines.
You can run the RDBMS for an OLAP Metadata Catalog on any platform as long as you have the ODBC driver and database client software required to connect to the catalog from the computer that runs DB2 OLAP Integration Server. You can also run the RDBMS for the relational data source that you use to create OLAP models and build metaoutlines on any platform, if you have the ODBC driver and database client software required to access the data source.
The RDBMS for the OLAP Metadata Catalog can be different from the RDBMS for the relational data source, and the platforms for the two RDBMSs do not need to be the same.
You can have more than one OLAP Metadata Catalog and, by using the XML Import/Export utility, you can move OLAP models and metaoutlines from one OLAP Metadata Catalog to another OLAP Metadata Catalog.
