22 Information us .data: Data are streams of raw facts . Information is data shaped into meaningful form.
23 Computer Based Information Systems CBIS Components PeopleDataSoftwareHardwareNetworkTechnologyFoundation
24 Information systems :Three activities produce information organization need:Inputs : captures raw data from organization or external environment .Processing : converts raw data into meaningful form.Output : transform processed information to people or activities that use it.feedback : output returned to appropriate members of organization to help evaluate or correct input stage

39 Information technology enhances business process in two main ways: Increasing efficiency of existing processEnabling entirely new process that are capable of transforming the businessChange flow of information .Replace sequential steps with parallel steps.Eliminate delays is decision making.
40 2.2 Types of information systems: Transaction processing systems )TPS).Management information systems (MIS).Decision support systems (DSS).Executive support systems(ESS).
41 1. Transaction processing systems(TPS): Perform and record daily routine transaction necessary to conduct business .Allow managers to monitor status of operations and relations with external environmentServe operational levels.Serve predefine , structured goals and decision making.

44 4. Executive support systems(ESS): Support senior management .Address non routine decision requiring evaluation .Integration data about external events as well as summarized information from internal MIS and DSS.
45 Systems from constituency perspective : Transaction processing systems : supporting operational level employee.Management information systems and decision –support systems :supporting managers.Executing support systems :supporting executives.
46 Relationship of systems to one anther: TPS :major source of data for other systems.ESS : recipient of data from lower –level systemsData may be exchanged between systems .In reality ,most business systems only loosely integrated.
