Visualize SAP HANA Schemas Without HANA Studio

SAP HANA runs entire S/4HANA and BW/4HANA landscapes from an in-memory column store — and scatters their data structures across dozens of application schemas. DbSchema reads HANA's catalog views and gives architects interactive ER diagrams, a desktop SQL client, and shareable documentation.

Tables, column views, and cross-schema relationships on one canvas
HANA SQL with system views and column store functions
Documentation stakeholders read without HANA system access

DbSchema presenting SAP HANA schemas as an interactive ER diagram

Trusted by teams at

One HANA Instance,
Dozens of Application Schemas

The platform answers analytical queries in memory, instantly — but ask it how its own schemas relate and you are writing catalog-view queries by hand. In a grown SAP landscape, hundreds of interdependent tables hide behind schema boundaries no single screen shows.

DbSchema builds that missing screen: an interactive ER diagram assembled from HANA's catalog views, spanning every schema your user can reach.

Navigate, Query & Publish
HANA Schemas from One Desktop

For the architects who keep S/4HANA and BW/4HANA understandable.

Organize SAP HANA schemas into readable diagrams

Hundreds of Tables, Kept Readable

Place tables, column views, and relationships from multiple HANA schemas side by side, then split the landscape into focused, color-coded diagrams.

Execute SAP HANA SQL from the DbSchema editor

The Dialect, Not a Subset

Run HANA SQL — system view queries and column store functions included — inspect row counts, and validate data without opening HANA Studio or the Web IDE.

Publish SAP HANA schema documentation as HTML

Reviewable Without System Access

Generate HTML documentation of tables, views, column types, primary keys, and relationships — a reference implementation teams hand to non-technical reviewers.

Version the HANA Model
the Way You Version Code

The ER diagram and the SQL editor ship free in the Community edition. Pro saves the HANA schema as a model file for Git — branch it, diff it, review it like application code — and compares development against production systems. The same 15-day trial in the installer unlocks it.

Ports and Drivers Across HANA Deployments

DbSchema reaches HANA directly over JDBC — no SAP GUI required. Download the SAP HANA JDBC driver (ngdbc.jar) from the SAP Development Tools page and register it under Connections > Manage Drivers. Single-container systems listen on port 39015; multi-tenant systems use 3[instance]15 — 30015 for instance 00 — giving a URL like jdbc:sap://host:39015?databaseName=HXE.

For HANA Cloud, swap in the cloud instance hostname and add your IP address to the allowed IP list before connecting. The SAP HANA JDBC driver page has the full walkthrough.
