- Data Class of Database Tables

For the database platform Oracle, the data class determines the physical area (tablespace) of the database in which a DDIC database table is created and is otherwise 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 frequently changed. 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)>
DDIC database tables for customer developments in a separate tablespace.

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