OVERVIEW
An Entity Relationship Diagram (ERD) is a deliverable that is created during the logical data modeling process that focuses on the data, unlike a DFD that focuses on the processes. The data in an information system that are created, stored, and utilized by a user are referred to as Entities, Attributes, and Relationships and are represented in ERDs as graphical pictures.
In this activity, you will create three Entity Relationship Diagrams (ERDs) in an individual practical exercise utilizing Microsoft Visio®. You will create your ERDs in three different cardinalities, One-to-One, One-to-Many, and Many-to-Many.
REQUIREMENTS
