Which system is primarily concerned with managing daily business transactions?

The correct answer focuses on the Transaction Processing System (TPS), which is designed specifically to handle and manage the vast amounts of daily transactions that occur within a business. A TPS processes data from transactions ranging from sales and orders to payroll and inventory updates.

The primary function of a TPS is to ensure the efficient and accurate recording, processing, and storage of these transactions, as well as to maintain data integrity. It operates in real-time and facilitates high-volume data input, which is crucial for businesses that rely on transaction data for their operations and strategic decision-making.

While other systems, like the Management Information System (MIS), provide oversight and analysis of data collected from various sources, and the Executive Information System (EIS) offers high-level managerial insights, they do not focus primarily on the day-to-day transaction processing. The Decision Support System (DSS) is concerned with supporting decision-making processes using data analysis, making it more strategic rather than operational. Thus, a Transaction Processing System stands out as the tool dedicated specifically to the management of daily business transactions.
