Entity Relationship Diagram (ERD)
An Entity Relationship Diagram (ERD) is a snapshot of data structures. ERDs show entities in a database and relationships between tables within that database. It is essential to have one of these if you want to create a good database design. The patterns help focus on how the database actually works with all of the interactions and data flows, although another useful tool is a Data Flow Diagram (DFD) which more directly describes this.
