Use the data warehouse matrix to:

Document Design – Document the high-level design of your data warehouse
Estimate – Rate facts and dimensions by complexity. The spreadsheet automatically generates estimates.
Plan – Make sprints that adhere to a master design.
Collaborate – Share the Matrix and design with other developers.

To use the spreadsheet, you simply:

Add your Facts and Dimensions and their relationships.
