A captured object represents an object in the captured third-party database, and a converted object represents an Oracle model of that object as it will be created in the Oracle database. Views are virtual tables (analogous to queries in some database products) that select data from one or more underlying tables. Oracle Database provides many view creation options and specialized types of views (such as materialized views) to meet a variety of enterprise needs. An index is a database object that contains an entry for each value that appears in the indexed column(s) of the table or cluster and provides direct, fast access to rows. Indexes are automatically created on primary key columns; however, you must create indexes on other columns to gain the benefits of indexing. A directory object specifies an alias for a directory (called a folder on Windows systems) on the server file system where external binary file LOBs (BFILEs) and external table data are located.
Files created in (or moved into) SQL Developer must be stored in the Subversion working copy. Before you can work with a Subversion repository through SQL Developer, you must create a connection to it. When you create a local Subversion repository, a connection to it is automatically created, and this can be seen in the Versioning navigator. SQL Developer provides integrated support for the Subversion and Git versioning and source control systems, and you can add support for other such systems as extensions by clicking Help, then Check for Updates. The SQL Developer documentation does not provide detailed information about the concepts and operations of such systems; it assumes that you know them or can read about them in the product documentation.

A SQL Worksheet window is also opened for the connection.To create a separate unshared worksheet for a connection, click in the worksheet and use Ctrl+Shift+N.
The FROM clause of the query can name tables, views, and other materialized views. Collectively these objects are called master tables (a replication term) or detail tables (a data warehousing term). The databases containing the master tables are called the master databases. Edition-based redefinition, introduced in Oracle Database 11g Release 2 (11.2), enables you to upgrade the database component of an application while it is in use, thereby minimizing or eliminating down time. To upgrade an application while it is in use, you copy the objects that comprise the application and redefine the copied objects in isolation.
