ERD (Entity Relationship Diagram)

ERD stands for Entity Relationship Diagram and shows “the relationships of entity sets stored in a database. An entity in this context is a component of data. In other words, ER diagrams illustrate the logical structure of databases” (Smartdraw 2015).

This is the resulting ERD from our group meeting, which Chris has put into an image.  It took longer than I anticipated as there was a lot to consider when deciding what needed to have its own table and which values to use.
