This is my best discover of the week... sometimes I've to work with different databases (such as SQL Server, Oracle, MySQL) and what I hate a lot is to change tool to interact with the DB (really boring to install SQL Client tools or Oracle Client tools on every PC).
The tool that satisfy my needs is Aqua Studio, a database query and administration tool that allows developers to easily create, edit, and execute SQL scripts, as well as browse and visually modify database structures. Aqua Data Studio provides an integrated database environment with a single consistent interface to all major relational databases. This allows the database administrator or developer to tackle multiple tasks simultaneously from one application.
It's really powerful and rich of useful features (a little thing I love for example is the autocompletion on SQL statements).
Absolutely recommended, expecially if you work with different types of databases.
