You have been asked to develop a data model for TV Guide. Consider the following business rules: • There are many channels on TV

• Each channel broadcasts many shows.

• Some shows are broadcast multiple times over the course of a week. (i. e. Showtime might show The Tudors Sundays at 10:00 PM and Tuesday at 9:00 PM)

• A show will have multiple actors

• An actor has a specific role in each show and can be in multiple shows (i. e. Chris Noth is Mike on Law & Order and Mr. Big on Sex and the City)

Task

Your task is to study the business objectives and model the data and relationships to support these objectives. You must create an Entity-Relationship Model. This should be a high-level model, meaning, unless necessary for understanding, you do not need to specify additional attributes for your entities and relationships other than ones described or implied above. You do need to identify all entities, relationships, attributes and cardinalities according to the description above. These specifications might not be as clear or as formally defined as might be needed, but you are the data modeler, you can see through this, and when you can't, you write your assumptions and proceed anyway. Again, if you need to make assumptions, ensure you document them at the bottom of your diagram.
