Dimensional Modeling - Design Changes

The following changes are anticipated to the design after the data warehouse is up and running

1. Adding new unanticipated facts (that is, new additive numeric fields in the fact table), as long as they are consistent with the fundamental grain of the existing fact table.

2. Adding completely new dimensions, as long as there is a single value of that dimension defined for each existing fact record.

3. Adding new, unanticipated dimensional attributes.

4. Breaking existing dimension records down to a lower level of granularity from a certain point in time forward.
