Free Graphical Database Design Tool

Manage Databases Visually

Using DbSchema, you will interact with the database using the mouse. Even if you are not an SQL expert, you will be able to create new tables, columns, or foreign keys, explore the data from multiple tables, create reports or generate test data.

HTML5 Documentation

Complex databases need good documentation. Using DbSchema, you can organize the tables in multiple layouts, add comments, and generate HTML5 or PDF documentation. The documentation is using an interactive diagram image, where you can read the comments as mouse-over tooltips. The image below is such an example.

Key Features

Conceptual & Logical Design

The conceptual and logical designs are database-independent and can use many-to-many, one-to-one relationships. The design can be converted to a physical design by applying data type and naming conversions.

What Customers Says

Many compliments! It is one of the best software I've ever seen.

"The project team I am reporting to really likes the HTML5 documentation I send them. Thank you again for this brilliant software. I am recommending it to all my colleagues."

"Using Relational Data Editor I can see table data from multiple tables without writing SQL queries, it's like a child's play."

"I've had some time to play with and get acquainted with DbSchema. I am impressed. It never crashed once, it's very intuitive, and the compare/sync wizard is all I expected."

"DbSchema is to databases what an artist's brush is to the canvas by putting the art back into the schema management by making it painless and visually appealing. Easily communicating complicated schemas to non-technical people has brought them into the process without the SQL and geeky diagrams. Should be in every developer's toolbox."
