Final answer:
Correct answer is D) .A Transaction Processing System (D) is typically a major source of data for other systems, such as Decision-Support Systems (A), Executive Support Systems (B), and Knowledge Management Systems (C), which rely on accurate and timely information to support decision-making processes.
Step-by-step explanation:
A Transaction Processing System (TPS) is typically a major source of data for other systems. It includes human-software interactions in complex automated systems, especially the decision-making processes of workers as they are supported by the software system. TPS systems are essential in capturing transaction data, which can be used by decision-support systems, executive support systems, and knowledge management systems for further analysis and reporting.
According to Essential Knowledge 5.A.1 and 1.A.1, a system is an object or a collection of objects that are treated as having no internal structure. In the context of a TPS, this means it functions as a singular entity focusing on capturing and processing data from business transactions without detailing the complexities within the system itself.
