DbSchema lets you design, manage, and document SAP MaxDB databases. Create ER diagrams, define tables and columns, and generate SQL scripts - with or without a live database connection.
Use Git to share the design, compare it with the SAP MaxDB database, and deploy changes. DbSchema also includes a data editor, query builder, and HTML5 documentation - everything you need in one tool.

SAP MaxDB (originally known as SAPDB) is an enterprise-grade relational database tightly integrated with SAP NetWeaver application servers. While less widely known than SAP HANA, MaxDB remains in active use in SAP R/3, ECC, and industry-specific SAP installations. DbSchema provides a modern visual interface for exploring MaxDB schemas, making it practical for SAP Basis administrators and developers to document and maintain database structures without relying solely on command-line tools.
DbSchema connects to SAP MaxDB and reads the schema catalog, displaying tables, views, and foreign key constraints as an interactive entity-relationship diagram. This is especially useful for large SAP installations where the database schema contains hundreds of tables with complex interdependencies that are difficult to trace through system queries alone.
DbSchema's SQL editor supports MaxDB's SQL dialect, allowing you to run queries, inspect stored procedures, and validate table data directly from the application. This removes the need to switch between separate tools when exploring or troubleshooting a MaxDB installation in an SAP landscape.
Documentation for SAP MaxDB databases is often limited to system-generated exports or manually maintained spreadsheets. DbSchema auto-generates navigable HTML documentation from the live schema, capturing table descriptions, column data types, indexes, and relationship diagrams — suitable for system auditors or new team members who need a reliable structural reference.
SAP MaxDB listens on port 7210 by default. The JDBC URL format is:
jdbc:sapdb://host:7210/dbname.
The JDBC driver class is com.sap.dbtech.jdbc.DriverSapDB.
Download the SAP MaxDB JDBC driver from the SAP MaxDB developer tools package (available on the SAP
Community Network) and add the JAR via DbSchema's driver manager under Connections > Manage Drivers.
Ensure the MaxDB X Server service is running and accepting TCP connections on the configured port before
attempting a connection.
