5. Transaction Processing Systems
 Large amounts of data are processed.
 The sources of data are mostly internal, and
the output is intended mainly for an internal
audience.
 The TPS processes information on a regular
basis: daily, weekly, monthly, etc.
 Large storage (database) capacity is required.
 High processing speed is needed due to the
high volume.

6. The Major Characteristics of TPS
 TPS basically monitors and collects past
data.
 Input and output data are structured (i.e.,
standardized).
 A high level of accuracy, data integrity,
and security is needed.
 High reliability is required.
