Week 3 Discussion

Discussion Question: Understanding Transaction Processing Systems

The nervous system of many organizations is the Transaction Processing System (TPS). As described in Week One,

accurate data is the foundation of information and knowledge transfer in an organization. The key requirements of a

TPS are:

• One or more users accessing the system simultaneously

• Data that is moving through the system is protected from disruptions in the process

• It is mandatory that a transaction can be reversed

• All transactions must have an audit trail

Respond to the following topics on a TPS in use at your company or one that you use in your daily life, such as an

ATM:

• Describe the purpose of the system and the data that is collected.

• Describe the departments that receive and process the data.

• Describe some of the managerial reports produced by the system and how the report assists in decision making.

• Describe the benefit to your company of having such a system.
