A table is a set of rows. Each row in a table has the same number of columns and contains a value for each column.

The database system recognizes the following table types:

Base table

Is stored permanently; system tables and tables that contain application data

Results table

Is created from one or more tables when a SELECT statement is executed, and is deleted again at the end of the session

Join table

Special results table that is created when two or more tables are linked

System table

Base table that contains system information (information about the database objects, states, statistics, monitor data; loader system tables)

Temporary table

Special base table that is deleted at the end of the session; used by the TEMP schema

View table

A table derived from base tables whose definition is stored permanently; does not contain any data itself, but is only used to view the data

Tables grow and shrink automatically and without any administrative intervention. Internal striping within the database means that the data belonging to a table is distributed equally to all data volumes. It is not possible to determine how the tables are assigned to the data volumes; however, it is not necessary to know this.
