Once I needed a database designing tool and found this one. It has many features that are really useful. But it’s no open source. So you can utilize it for 1 month.

Report Generator

Database Designer for MySQL can generate comprehensive printable reports for you. This gives you the possibility of getting a hard copy of the report by printing it. After that you may approve your model with colleagues and managers.

Generated reports contain information about all tables, their indexes and columns, references.

You can get reports in HTML format.

SQL Editor and Executor

With Database Designer for MySQL you don’t need any external tools for executing simple SQL statements and queries. The SQL Executor tool allows you to modify the existing structure of a local or remote database and even view data by running SELECT/INSERT/UPDATE/DELETE SQL statements.

Multi-document Interface

Database Designer for MySQL has Multi-Document Interface. This means that you can edit multiple documents simultaneously. You may place more than one diagram onto the working space, switch between them quickly, compare them, and drag objects from one to another.
