The PostgreSQL OMRS Repository Connector provides a repository implementation that stores metadata in a PostgreSQL Database. Each Open Metadata Repository uses the same table structure within its own Database Schema. This database schema is managed by a single instance of the PostgreSQL Repository Connector.

Access to the PostgreSQL Database Schema is provided by the [JDBC Resource Connector](/connectors/resource/jdbc-resource-connector). This connector manages the SQL Queries, connection management and use of the secrets store for security connections.

The diagram below shows the tables used in the PostgreSQL Database Schema.
