Admin is entirely written in Java. It uses Swing GUI Components and JDBC to connect to databases. It has been succesfully tested with MySQL, Derby, InstantDB, Oracle, Empress, MS SQL Server, and PostgreSQL. You can have a tree view of the RDBMS or pick a single instance to have a look at its metadata. It allows you to create, modify, and drop tables and to create indices on a table. The dynamic form makes it easy to enter data into a certain table, and the guided query makes it easy to retrieve data from a table and to export it. Java developers will probably enjoy the code generator doing an OO relational wrapper and a swing GUI for them. There is a tool with which SQL statements can be enriched with a few commands, generating a GUI to easily select data from a DB. You can also export and import data and transport it from one DBMS to another.
