Working with database objects
To work with any object, select and expand the respective object node. The most common node you'll work with is the Tables node. This displays all of the tables the user owns (all of the tables in the schema). Each of the object nodes is identified by an icon, and the Tables node highlights some of the main table types using these icons. Not all are singled out, but the more commonly used ones are. If you expand the HR Tables node, then the COUNTRIES table, which in the sample is an index-organized table, is identified by the slightly different table icon used. Partitioned tables are also distinguished from regular, simple tables using icons. The following screenshot displays the index organized, regular, external, partitioned, and temporary icons:
