Logical Data Modeling - Data Modeling for MongoDB - page 142

Recall from our conceptual data modeling discussion that Student Attrition is an example
of a fact table (on a conceptual and logical data model often called a “meter”). A meter is
an entity containing a related set of measures. The measures on this model determine how
the student attrition business process is doing—in this case, studentCount . Often the meter
contains many measures. Also, often the dimensions contain many attributes, sometimes
hundreds of them. On this model we have a number of dimensions, such as University ,
that only contain a single attribute.
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.
