Jaqua (JAva QUery Analyzer) is a platform-neutral and database-vendor-independent database-administration- and ad-hoc SQL-query-tool.
It provides a thin (graphical) layer between the database and the underlaying JDBC-driver, so it can be used with every JDBC-enabled database. JDBC-drivers for almost every known database may be found here.

Jaqua is a 100% pure Java application. It supports parallel interaction with unlimited databases, simultaneous editing and running of scripts and much more...
Jaqua also helps to get a quick view over important database-metadata and/or connection properties (transactions allowed?, current transaction level, supported table-types etc.).

A new, sophisticated ("Explorer"-like) query GUI makes it possible to evaluate the result of every single statement in your script in a second (Screenshots).

Jaqua was designed for database-administrators, -application-developers, -users, JDBC-driver-vendors and everybody who looks for a fast, stable and transparent solution to interact with a database (via SQL).
