A working ERD (Entity-Relationship Diagram) in computer science is a visual representation that illustrates the entities within a system and their relationships. It is primarily used to model database structures.
Typically, database designers, software developers, and system analysts are required to create and file working ERD diagrams to document and communicate database designs.
To fill out a working ERD diagram, one should define the entities, identify their attributes, specify the relationships between entities, and use standardized notation to create the visual layout.
The purpose of a working ERD diagram is to provide a clear and organized depiction of data structures, facilitate communication between stakeholders, and serve as a blueprint for database development.
An ERD must report entities, their attributes, and the relationships among those entities, including cardinality and participation constraints.
