An Entity Relationship Diagram (ERD) is the visual representation of all data stored in a system and their relationships. It is a means of visualizing how the information a system produces is related. There are three main components an ERD:
At first glance an ERD looks very much like a flowchart. It is the specialized symbols, and the meanings of those symbols, that make it unique.
When documenting a system or process, looking at the system in multiple ways increases the understanding of that system. ERD diagrams are commonly used in conjunction with a data flow diagram to display the contents of a datastore. They are very helpful when needing to visualize how data is connected in a general way, and when constructing a relational database.
