The application toolbar provides quick access to the most common functions.
The list of databases is a tree list of the registered data sources and the databases that each data source contains.
When you select a database from the list of databases and select the procedures, tables, users or views node underneath it the list of those items is populated. From this list you can select an item and extract the SQL used to create it.
The documents area holds the currently open queries. You can arrange these documents (tile or cascade) using the Window menu item on the main screen.
The error history box at the bottom of the screen shows the most recent SQL errors. You can get the details of any error by double-clicking on that error message.
