Index-organized tables are discussed in Partitioned tables enable your data to be broken down into smaller, more manageable pieces called partitions, or even subpartitions.Each partition can have separate physical attributes, such as compression enabled or disabled, type of compression, physical storage settings, and tablespace, thus providing a structure that can be better tuned for availability and performance.Oracle Database supports several methods of table compression. When you use basic table compression, warehouse compression, or archive compression, compression only occurs when data is bulk loaded into a table.When you use advanced row compression, compression occurs while data is being inserted, updated, or bulk loaded into a table.If you do not specify a tablespace in a statement, the table is created in your default tablespace.When specifying the tablespace to contain a new table, ensure that you understand implications of your selection.Table compression is completely transparent to applications.It is useful in decision support systems (DSS), online transaction processing (OLTP) systems, and archival systems.
