Entity Relationship Diagram
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!
How to create your own Entity Relationship Diagram
Identify all the entities existing in your system. Each entity only needs to appear in the diagram once.
Fill in all the entities and their relevant attributes.
Use connectors and ERD symbols to identify and represent the relationships between entities.
At the end, you can share the diagram with your teammates to collaborate and ensure the entity relationships are well-defined.
