Part Number A95295-02
A measure is an OLAP metadata entity. This means that it is a logical object, identified by name and owner, within the OLAP Catalog.
Measures represent data stored in fact tables. The fact tables may be relational tables or views. The views may reference data stored in analytic workspaces.
Measures exist within the context of cubes, which fully specify the dimensionality of the measures' data. Measures are fully described in "OLAP Metadata Model".
Use the procedures in the
CWM2_OLAP_MEASURE package to create, drop, and lock measures, to associate a measure with a cube, and to specify descriptive information for display purposes.
The parent cube must already exist in the OLAP Catalog before you can create a measure.
