When you select certain nodes in the DB Structure view, properties and values appear in the DB Details view.
The top-level nodes in the Oracle DB Structure view are Database, Monitor, Security, and Instance. You can use filters to show only certain schema items in the view; you cannot, however, create or edit schema.
Database
The root node Database is at the top level of the DB Structure view. If the database supports catalogs and you have selected Show catalog in the DB Navigator preferences, all catalogs appear below the database node. If you have selected Show schema in the DB Navigator preferences, all schemas appear below the database node.
Beneath the schema and catalog nodes, the following child nodes appear:
| SYNONYM | All aliases that were created in SQL against tables. SQL statements can use these aliases instead of the name specified when the schema item, such as table, view, or synonym, for example, was created. The child nodes contain only tables, views, or other synonyms. They do not display columns or indexes of the tables. |
| TABLE | Displays all
application tables. Table nodes expand to show columns and indexes.
When you select a table name, data and meta-data appear in the DB
Details view. Note: Since tables are
displayed in ASCII order and sorting is case-sensitive, all
lowercase table names sort after the uppercase table
names.
|
| VIEW | Displays the names of all created views. A SQL view allows you to extract rows and columns from one or more related tables and to treat the resulting data set as a virtual table that can be viewed or updated. |
| SEQUENCE | Displays all sequences, which create an incremented, serial list of numbers applied to a column in a database table. |
| PACKAGE | Displays all packages, which contain specific procedures, functions, and other schema items in one entity. |
| PACKAGE BODY | Displays details about each package body, including the SQL code, and properties and their values. |
| FUNCTION | Displays all functions, or pieces of a program that you can use separately from the remainder of the program. |
| PROCEDURE | Displays all procedures that are stored in the database and available for reuse. |
| TRIGGER | Displays all triggers, which you define to run when you modify a table or view or when a particular action occurs. |
| SESSIONS | Displays information about the current user-to-database connection in the DB Details view. |
| JAVA SOURCE | Displays all Java objects. |
| DATABASE LINK | Displays all database links. Each database link is present as a local database object and contains specifics necessary for connecting to another database. |
Monitor
When you select the Monitor node, the following subnodes appear:
| SESSIONS | Displays information about the current session, such as username, Session ID, machine name, and the user's logon time, in the DB Details view. |
| JOBS | Displays information about a job, or task, that you run once or on a particular schedule, in the DB Details view. |
| TOP SQL | Displays SQL executions in the DB Details view, enabling you to see how resources are affected when a SQL statement is executing. |
Security
When you select the Security node, the following subnode appears:
| Users | Displays all authenticated users by username, user ID, and the date on which the user was created. |
Instance
When you select the Instance node, the following subnodes appear:
| System Parameters | Displays all system parameters (retrieved from the v$system_parameter table) in a viewer. |
| TableSpace | Displays all table spaces, or logical storage units, in the database. |
