The database navigator displays catalogs, schemas, tables and columns of a database in a tree format.
This allows you to see the hierarchical structure of the database. If there is only one
item in a tree, that item will be collasped to minimize the number of clicks needed to reach
a node. With a collaspe, the name of both nodes combined with a period. There are two features
of the database navigator that are important: Regex Filter and Query Builder.
Query Builder
On each table node there are options to generate SQL statements with the query builder. Right clicking
on the node will bring four types of query builders: select, update, insert, and delete. Double clicking
on a table node will run "SELECT * FROM <table selected>".
