org.olap4j.metadata.Catalog

Catalogs are the second element of the hierarchy of metadata objects. A Catalog contains one or more {@link Schema}s and has a parent {@link Database}.

Some OLAP servers may only have one Catalog. Mondrian is one such OLAP server; its sole catalog is called "LOCALDB".

To obtain the collection of catalogs in the current server, call the {@link OlapConnection#getOlapCatalogs()} method.

The hierarchy of metadata objects, rooted at the connection from which they are accessed, is as follows:

{@link org.olap4j.OlapConnection}

{@link Database}

{@link Catalog}

{@link Schema}

{@link Cube}

{@link Dimension}

{@link Hierarchy}

{@link Level}

{@link Member}

{@link Property}

{@link NamedSet}

{@link Dimension} (shared)
