Data representation considerations

Different systems represent data in different ways. When data is moved from one system to another, data conversion must sometimes be performed.

Products supporting DRDA automatically perform any necessary conversions at the receiving system.

To perform conversions of numeric data, the system needs to know the data type and how it is represented by the sending system. Additional information is needed to convert character strings. String conversion depends on both the code page of the data and the operation that is to be performed on that data. Character conversions are performed in accordance with the IBM® Character Data Representation Architecture (CDRA). For more information about character conversion, see the Character Data Representation Architecture.
