Table 7.5 Oracle 9i data Table types

Way	Characteristics
Relational tables	Default table types that store persistent data and can be partitioned, which improves table performance and is easy to manage
Temporary tables	Store private data or specific data in a session, and other users in the database cannot use the data
Index Table	Storing data in the same way as structured primary keywords, unlike relational tables, tables and primary keys cannot be stored separately
External table	Data is stored in a file outside of an Oracle database and can only be read so that no index can be stored in an external table
Object Table	Support for object-oriented data tables
