2. How do systems serve the various levels of management in a business?
* Describe the characteristics of transaction processing systems (TPS) and the role they play in business.
* TPS keep track of the daily information from the various transactions a business does. Basic transactions such as sales, receipts, cash deposits, inventory, and shipping. It make answering questions and tracking business transactions easier.

MIS differs from DSS because MIS is used for routine middle management decisions while DSS is used for non-routine middle management decisions.
* Describe the characteristics of decision support systems (DSS) and how they benefit businesses.

* Describe the characteristics of executive support systems (ESS) and explain how there systems differ from DSS.
