Uses of Entity Relationship Diagrams

An entity relationship diagram provides a model of data-based entities in a system, along with their attributes and relationships. At their most basic level, databases are information banks designed to store and retrieve data based on specific attributes and interactions.

Plotting out the logical structure of these data relationships is a crucial part of designing, implementing, scaling, and troubleshooting information systems. By planning and documenting the database, engineers can better understand system requirements and evaluate any issues that may arise.

Use this diagram when improving databases, streamlining system processes, integrating or designing new software, managing bugs, and more. Sign up for Cacoo and quickly start making the Entity Relationship Diagram your own!
