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.
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.
