Hi Sahasra

I am sending u some pts on data class:-

The Data class determines in which tablespace the table is stored when it is created in the database.

What is a Size Category?

The Size category describes the probable space requirement of the table in the database. How Many types of size categories and data classes are there? There are five size categories (0-4) and 11 data classes, only three of which are appropriate for application tables:

- APPL0 - Master data (data frequently accessed but rarely updated)

- APPL1 - Transaction data (data that is changed frequnetly)

- APPL2 - Organisational data (customizing data that is entered when system is

configured and then rarely changed)

Reward pts if help.

HI,

Sahasra

If you choose the data class correctly, your table is automatically assigned to the correct area (tablespace or DBspace) 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. There are the following 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.

Two further data classes, USR and USR1, are provided for the customer. These are for user developments. The tables assigned to these data classes are stored in a tablespace for user developments.
