Data Class of Database Tables

For the database platforms Oracle and Informix, the data class determines the physical area (tablespace) of the database in which a database table is created (otherwise it is ignored). The most important data classes for application data are:

  • APPL0 (master data)
Data that is rarely changed. One example of master data is data in a table of addresses, such as names, postal addresses, and telephone numbers.
  • APPL1 (transaction data)
Data that is changed a lot. One example of transaction data is warehouse stock that changes each time an order is placed.
  • APPL2 (organizational data)
Customizing data specified when the system is configured and then changed only rarely. One example is the table T005 that contains the country codes.
  • USR and USR1 (customer data)
Database tables for customer developments in a separate tablespace.

There are also other data classes for system tables used internally by the runtime environment, such as SDIC for ABAP Dictionary tables.
