Bring MonetDB's Column-Store Schema to a Visual Canvas

Connect DbSchema to MonetDB and turn the live schema into an editable visual model: explore relationships in interactive ER diagrams, plan changes on the canvas, and generate reviewed SQL scripts for deployment.

The workflow is designed for visual modeling, schema documentation, and deployment — keep an offline model in Git, collaborate across teams, and publish documentation that developers, analysts, and stakeholders can navigate in minutes.

Schema Visualization for MonetDB's Columnar Architecture

MonetDB is a pioneering open-source column-store database developed at CWI Amsterdam, designed for analytical workloads that benefit from column-at-a-time execution. Its schema model includes tables, views, functions, and R-tree indexes organized within named schemas — the same structural building blocks a relational engineer already expects, just tuned for scan-heavy analytical queries rather than row-oriented transactions. While MonetDB excels at analytical SQL workloads, its tooling ecosystem is more limited than mainstream databases, and teams often end up piecing together schema knowledge from catalog queries. DbSchema bridges this gap by providing a visual schema explorer and SQL client that connects to MonetDB via JDBC, free to use for reverse engineering and browsing in the Community edition.

ER Diagrams for MonetDB Schemas

DbSchema reads MonetDB's system catalog and renders tables, views, and relationships as an interactive entity-relationship diagram. This visual representation helps onboard new team members and documents the analytical data model for a MonetDB-backed application or research database. Layouts can be rearranged on the canvas to group related tables, and the Pro edition saves the resulting model to a file that can be versioned in Git alongside the rest of the project.

SQL Editor for MonetDB Analytical Queries

The DbSchema SQL editor connects to MonetDB and supports its SQL dialect, including window functions, user-defined functions, and MonetDB-specific aggregate operations. Run analytical queries and inspect result sets without using the mclient command-line tool.

Schema Documentation for MonetDB Data Models

DbSchema generates HTML documentation from MonetDB's system catalog, capturing table schemas, column types, constraints, and views. This documentation helps analytical engineering teams maintain a clear reference for their MonetDB data model alongside query logic and ETL pipelines.

Connect DbSchema to a MonetDB Instance

MonetDB requires its own JDBC driver, so register that first and the rest of the setup is standard.

  1. Download the MonetDB JDBC driver from monetdb.org/downloads.
  2. Open DbSchema's Connections > Manage Drivers screen and add the JAR under driver class nl.cwi.monetdb.jdbc.MonetDriver.
  3. Create a new connection, select MonetDB, and enter the host with port 50000 (the MonetDB default) to build the URL jdbc:monetdb://host:50000/dbname.
  4. Provide your credentials and connect — DbSchema reads the system catalog and renders the ER diagram.

MonetDB's default configuration restricts connections to localhost; for remote access, edit monetdb.conf to bind the server to the appropriate network interface before connecting.
