Firstly I have learned that ESS helps managers make strategic decisions affecting the entire company. The decisions use internal and external data to give executives the information they need to determine the proper course of action in unstructured situations.
What i have learned next is DSS. It is an organized collection of people, procedures, software, databases and devices used to support problem-specific decision making. It is used when problem is complex and to support unstructured or semi-structured problems that require human judgment.
I also have known that TPS records the data from everyday operations throughout every division or department in the organization. Each division or department is tied together through the TPS to provide useful information to management levels throughout the company.
Moreover, I have found out about MIS. It is an integrated collection of people, procedures, databases and devices that provides managers and decision makers with information to help achieve organizational goals. It provides the right information to the right person in the right format at the right time.
Last but not least, I have learned about Expert System (ES). It is a part of a general category of computer applications known as artificial intelligence.
