For Dimensional
For our dimensional physical data model, these attributes are queried frequently and there-
fore need non-unique indexes:
departmentName
,
yearCode
, and
semesterCode
:
STEP 4: REVIEW AND CONFIRM
Previously, we identified the person or group responsible for validating the model. Now we
need to show them the model and make sure it is correct. Often at this stage after reviewing
the model, we go back to Step 1 and make some changes and then show the model again.
This iterative cycle continues until the model is agreed upon by the validator and deemed
correct so that we can move on to MongoDB implementation.
STEP 5: IMPLEMENT
We're done with our modeling, and now we can start creating documents within each of
these collections!
