Collate: Entity Relationship (ER) Diagrams
Overview
Entity Relationship (ER) Diagrams in Collate provide a visual representation of how tables are connected within a database. These diagrams offer a complete picture of your data structure by automatically detecting relationships based on constraints such as primary keys and foreign keys during metadata ingestion.

Automatic Detection of Relationships
Collate's metadata ingestion workflow identifies and extracts table relationships, ensuring that primary key and foreign key constraints are accurately represented. Once ingestion is completed, users can access ER diagrams at both the table level and database schema level.
Features of ER Diagrams
