Week 05

This is the most important week for our subject. Because during this week our lecturer explored clearly about types of main information systems such as TPS (Transaction Processing System), DSS (Decision Support System), ESS (Expert Support System), MIS (Management Information System) and ESS (Executive Support System). Also we learnt some other information systems.

These above mentioned information systems are divided into two groups. The two groups are Operation Support System and Management Support System. MSS, EIS, DSS is manage under Management Support System while TPS, ESS is manage under Operation Support System. ESS is use for making strategic decision, DSS and MIS is use for decision making and TPS is use for day to day info and operation.
Then, I also learn the main four systems that used is every organization to do their office work and its each role in that organization. They are such following. First, ESS is designed to be operated directly by executives without the need for intermediaries and easily tailored to the preferences of the individual using. Its characteristics support unstructured decisions, used only at the most senior management level, provide critical information for executives and managers and soon. Second, DSS is an organized collection of people, procedures, software, databases and devices used to support problem-specific decision making. It always used in a complex situation and it also helps manager to do the right things such handle large amount of data from various sources. Third TPS is an IS that captures and processes data generated perform the activities associated with transaction processing. It is used in operational personnel and supervisory levels. Finally, MIS is an integrated collection of people, procedures, databases and devices that provides managers and decision makers with information to help achieve organizational goals. It plays a role as provide the right information to the right person in the right format at the right time. There are many examples of MIS that is using in many organizations.
