`DIMENSION_ID`	`NUMBER`	`NOT NULL`	ID of the cube dimension
`DIMENSION_TYPE`	`VARCHAR2(17)`		Type of the OLAP cube dimension: `STANDARD` `TIME`
`AW_NAME`	`VARCHAR2(128)`		Name of the analytic workspace that contains the cube dimension, such as `GLOBAL`

`ADD_UNIQUE_KEY_PREFIX`	`VARCHAR2(3)`		`Add_Unique_Key_Prefix` flag of the OLAP cube dimension. Possible values: YES: This is the value if `AddUniqueKeyPrefix="True"` was set in the metadata. This tells the system to add the level name prefix to the dimension members. This should be done when a dimension member can have the same value across different levels, for example, New York (state) and New York (city). NO: This is the value if `AddUniqueKeyPrefix="True"` was not set in the metadata.
