A Windows desktop tool for designing databases with ER diagrams and generating SQL.
DeZign for Databases is a live Windows desktop tool from Datanamic for designing databases with entity relationship diagrams. Subscriptions start at €19 per user a month, billed yearly, and there is a 14-day free trial.
You draw a model, generate SQL to build the database, or import an existing database and keep the two in sync. It supports more than 15 databases, including Oracle, Snowflake, SQL Server, MySQL, PostgreSQL, Google BigQuery and SQLite. The May 2026 update (version 14.9) added Oracle 26ai, PostgreSQL 18 and MySQL 9.6. There are three editions, and the cheapest one leaves out native database import and the compare tools.
Bottom line: a good fit for a developer or DBA on Windows who wants a desktop modeler with fair prices. Mac and Linux users, and teams that want a browser tool, should look elsewhere.
Visual entity relationship modeling in IDEF1X or Crow's Foot notation, with domains, name templates and model checks.
Generate SQL DDL or database files from a model, or import from a live database or a DDL script.
Compare a model with a database in both directions. Expert can generate the alteration code to update the database.
Folder-based projects work with Git. Expert adds the server-based Datanamic Repository for multi-user work. Reports export to HTML, Word and PDF.
