Download the Cache JDBC driver, copy the JDBC URL into DbSchema, and start designing schemas with ER diagrams — free Community Edition.
A JDBC driver is a Java .jar library that lets applications connect to Cache.
DbSchema uses JDBC to reverse engineer schemas, run SQL, and generate documentation.
Driver files are usually published by the database vendor or an open-source project.
Host, port, database name, and SSL options are passed in a URL starting with jdbc:.
Each Cache driver uses its own syntax — see the connection details below.
InterSystems Caché is a high-performance object and relational database used in clinical healthcare systems (Epic, MEDITECH), financial applications, and government databases. It stores data as multi-dimensional objects while exposing a SQL interface through its %SQL engine.
The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.
DbSchema connects to InterSystems Caché using the JDBC driver and renders Caché persistent classes as SQL tables in the schema diagram. Use the ER diagram to document complex healthcare data models built on Caché.
Connect Cache, build your first ER diagram in minutes. No account required.
Get the Cache driver zip below and install DbSchema for Windows, macOS, or Linux.
In DbSchema, open Driver Manager, add the extracted JAR, and paste your JDBC URL.
Reverse engineer Cache, edit the model visually, and publish schema documentation.
After the JDBC driver connects, you get ER diagrams, SQL editor, schema sync, and HTML documentation in one desktop app. Compare DbSchema editions.
Reverse engineer Cache into an interactive diagram and edit structures visually.
Run SQL with autocomplete or compose queries without writing every join by hand.
Export HTML docs your team can browse without installing DbSchema.
Connection tips, ports, SSL, and schema design workflows on the database landing page.
Other drivers teams often configure alongside Cache.
Teams working with Cache often use these engines too. Explore dedicated guides and JDBC setup for each.
