Data class tells how the table is automatically going to be
assigned to the correct area of table space or Data base
space of the database when it is created.
Each data class corresponds to a physical area in which all
the tables assigned to this data class are stored.

Following are the data classes:

APPL0 (master data): Data which is seldomly changed. An
example of master data is the data contained in an address
file, such as the name, address and telephone number.

APPL1 (transaction data): Data that is frequently changed.
An example of transaction data is the goods in a warehouse,
which change after each purchase order.

APPL2 (organizational data): Customizing data that is
defined when the system is installed and seldomly changed.
An example is the table with country codes.

Data class in technical settings:

The data class defines the physical area of the database
(for ORACLE the TABLESPACE) in which your table is
logically stored. If you choose a data class correctly,
your table will automatically be assigned to the correct
area when it is created on the database.

The most important data classes are (other than the system
data):

APPL0 Master data
APPL1 Transaction data
APPL2 Organizational and customizing data

Master data is data which is frequently read, but rarely
updated. Transaction data is data which is frequently
updated. Organizational und customizing data is data which
is defined when the system is initialized and then rarely
changed.

There are two more data classes available, USR and USR1.
These are reserved for user developments. The tables
assigned to these data classes are stored in a tablespace
for user developments.

Note:The data class only has an effect on table storage for
the database systems ORACLE and INFORMIX.
