To hold the reference structures and templates relating
to a specific business dimension, you need to create a reference dimension.
The reference dimensions form the dimensional framework, which is
used for providing information when merging data and delivering dimension
data into data marts.
About this task
A reference dimension can contain hierarchies, auto-level
hierarchies, and lookups.
To create a reference dimension:
- Start IBM® Rational® Data Manager and load
the extract, transform, and load (ETL) catalog.
- Expand the catalog, click the Library node,
right-click Dimensions and click Insert
Reference Dimension.
- Type a name.
Note: Business name and description
are optional.
- If the dimension is based on time, select Dimension
Represents Time.
- Click OK.
