Instructions: Create a dimensional model for a particular business process involving gym membership. A customer can sign up for a membership of say one, three, six or twelve months.

On a particular day, the active members are those with a start date before the day and an end date after that day. Those who will expire next month are those where the end date is in a particular date range.
