Native metadata

IBM® Cognos® supports OLAP data sources as well as relational data sources. The term native metadata refers to objects such as models, packages, and queries that are based on an OLAP data source. A namespace that contains native metadata uses this icon modified namespace icon to indicate that it includes native metadata

to indicate that it is different from namespaces containing other types of metadata.

OLAP data sources are metadata rich data sources. Explicit modeling for these data sources is not enabled in Framework Manager and the package is published directly to the portal. For more information, see Creating and publishing packages based on OLAP data sources.

Levels are created using the generation names in the labels. If you want to alter the way levels are named, you can do this by changing the dimension build settings in the application that generated the cube. For more information, see the vendor documentation.

Relational data sources require dimensional modeling to enable them to work, and to be compatible with drill capabilities in the other studios. For more information about dimensional modeling, see Dimensions.

If you installed IBM Cognos components on UNIX servers, locate the file-based data source on a UNIX server. You should then use a UNIX path, such as /servername/cubes/Great Outdoors Company.mdc to access the file.

Compound packages contain both OLAP and relational metadata.
