A complete event matrix?
Keep the event matrix up to date! It’s not an initial planning tool or a one-time
modeling technique. Use it to document the ongoing data warehouse design.
Refer to it and update it whenever you are modelstorming. A well-maintained
matrix acts as a constant reminder to everyone to reuse and enhance conformed
dimensions.
