Name two-to-five entities (also known as entity classes in your text) that will be part of your database. Explain why you have chosen these entities. Using the Chen format as shown and discussed in the Oppel text, draw an entity-relationship (E-R) diagram for two entities including their relationship; for one of the entities, also name the identifier. Attach the diagram to your discussion post as a PDF document. (Hand drawn diagrams are not acceptable; you may utilize a software program or Microsoft Word symbols to depict your diagram aspects).
According to Oppel, An entity (or entity class) is a person, place, thing, event, or concept about which data is collected (2009).
The entities that I picked are:
1. Amount of medication errors within the unit in 2019
2. How many orders were verbal orders
3. Nurse / Patient ratio at the time of the error…..To access the solution click the icon below to purchase at $5
