Massaging Data

Especially when interfacing systems, it is often necessary to re-format or manipulate data from one format into another, to enable another system to accept the input, e.g. order processing output being input into the accounting system. Sometimes, the data will need to be massaged, e.g. by the removal of extraneous characters or the addition of some control characters. Whatever the exact requirements, such manipulation of data poses a threat to the integrity of the data, and thorough System Testing is advised.
