This assignment require you to apply the Data Modeling concept and skill learned from Chapter 6 to build an ERD based on the previous AVS case (A Video Store) from your Assignment 2 & 3.

Turn in an ERD with appropriate relationship sentences. You can use drawing tools in MS Word or MS Visio to create your ERD. Make sure your relationship sentences are consistent with your realtionshipe in your ERD.

Before a video can be put on the shelf, it must be catalogued and entered into the video database. Every customer must have a valid AVS customer card in order to rent a video.
