Introduction to information systems Basic Concepts and Applications
Objectives After completing this topic, the students will: Understanding the basic concepts of IS Knowing the different between IS and CS Understanding the basic ideas of IS applications After this class, the students are expected to able to understands the basic concept of IS. The student are also expected to know the different between the Information Systems and Computer Science, and have no confusion to distinguished the two of them. And at the end of this class, the students are expected to understand the basic idea of IS application,
Information Systems (IS) as a Discipline IS is an independent and broad academic field that borrows conceptual theories from social and technical ones, including: Management Accounting Behavioral Sciences Computer Sciences Decision Sciences ICT So, What is IS. We can say that IS
IS as Organizational Components The components that helps organizations achieve their goals, such as increasing profits or improving customer service by taking the advantages of information value in input, processing and output activities. From the organizational and managerial point of view, IS is all components that…
IS Components People Hardware Software Data Communication or/and Networking
IS Components IT/ICT People who use the system Procedures for people to be followed Information stored and processed in the system More detail we can say that the component of IS are include:
IS Components
Main activities in IS Input: Captures raw data from organization or external environment Processing: Converts raw data into meaningful forms Output: Transfers processed information to people or activities that use it Feedback: Output that is used to make changes to input or processing activities After this class, the students are expected to able to understands the basic concept of IS. The student are also expected to know the different between the Information Systems and Computer Science, and have no confusion to distinguished the two of them. And at the end of this class, the students are expected to understand the basic idea of IS application, 8
Information Systems Vs Computer Science As IS and CS share many common things, to distinguished them we can take some parameters:
Areas of IS Knowledge Foundation Concept Information Technologies Business Application Development Processes Management Challenges
The Fundamental Roles of IS in Business and Managerial Activities IS supports: Business Processes and Operations Decision Making Strategies For Competitive Advantage 11
Types of IS Operations Support Systems Management Support Systems
Operations Support Systems Systems that produce a variety of information products for internal and external use but do not emphasize that can best be used by managers. Transaction Processing Systems Process Control Systems Enterprise Collaboration Systems 13
Transaction Processing Systems Process data resulting from business transactions, update operational databases, and produce business documents such as sales, inventory and accounting systems. 14
Process Control Systems Monitor and control industrial processes production systems. 15
Enterprise Collaboration Systems Support team, workgroup, and enterprise communications and collaborations. Example: email, chat, videoconferencing groupware systems. 16
Management Support Systems Information systems that provide information and support for effective decision making by managers. These types of systems include executive information systems, decision support systems, and management information systems Management Information Systems (MIS) Decision Support Systems (DSS) Executive Information Systems (EIS) / Executive Support Systems (ESS) 17
Management Information Systems Provide information in the form of pre-specified reports and displays to support business decision making. Example: Sales analysis, production performance, and cost trend reporting systems. 18
Decision Support Systems Provide interactive ad hoc / direct computer support to managers during the decision making process. 19
Executive Information Systems / Executive Support Systems Provide critical information from MIS, DSS and other sources in easy-to-use to executive. 20
Trends in IS 21
IS applications Most of organization’s components are supported by IS application Integration is still a hot issue
IS application: Oracle Solutions
IS application: SAP Solutions
