Myna comes with a built in database administration application. You can define a datasource for your application to use within the data manager. After you create your datasource, you can then work directly on your database from within the data administrator. You can create, edit and delete tables, indexes, fields, etc. This eliminates the need for datbase administration software as well as extra ports being opened to the outside world.

The data administrator is written entirely in Javascript and Ajax. This makes it fast and easy to use, and you can customize if you need to.
