As you further consider the information problems and design of the database from your Week 1 discussion, address the following:

The data base will built on these questions based off of medication errors.

1. How many medication errors have occurred in the last year? 2. What was the nurse/patient ratio during each medication error? 3. What was the time of day these errors occurred?

1. Name two-to-five entities (also known as entity classes in your text) that will be part of your database.
2. Explain why you have chosen these entities.
3. Using the Chen format as shown and discussed in the Oppel text, draw an entity-relationship (E-R) diagram for two of the entities, name the identifier for the selected entities, and attach the drawing to your discussion post. Remember, an entity-relationship requires at least one other entity. Use a software program or Microsoft Word symbols to depict your diagram aspects.
