Database Deployment Manager (DDM) is a desktop oriented multi-platform database design tool that allows database administrators and programmers to create database structures (using an object oriented methodology) and deploy them into an existing database. The tool allows creation of diagrams to identify basic relations between the defined structures. You can import tables from various databases, either by fully reversing a database or just picking tables from various databases and injecting them into your solution. You can browse the databases and execute SQL queries on them. There is a unique SELECT query builder that makes the building of queries very easy without having to write a single SQL statement; just using point and click with the mouse.
