1. Introduction to information systems
Basic Concepts and Applications

2. 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,

3. 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

Computer Sciences
Decision Sciences
ICT
So, What is IS. We can say that IS

4. IS as Organizational Components

From the organizational and managerial point of view, IS is all components that…

5. IS Components People Hardware Software Data Communication
or/and Networking

6. 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:

7. IS Components

8. 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

9. Information Systems Vs Computer Science
As IS and CS share many common things, to distinguished them we can take some parameters:

10. Areas of IS Knowledge Foundation Concept Information Technologies
Business Application
Development Processes
Management Challenges

11. The Fundamental Roles of IS in Business and Managerial Activities
IS supports:
Business Processes and Operations
Decision Making
Strategies For Competitive Advantage 11

12. Types of IS
Operations Support Systems
Management Support Systems

13. 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

14. Transaction Processing Systems
Process data resulting from business transactions, update operational databases, and produce business documents such as sales, inventory and accounting systems. 14

15. Process Control Systems
Monitor and control industrial processes production systems. 15

16. Enterprise Collaboration Systems
Support team, workgroup, and enterprise communications and collaborations. Example: , chat, videoconferencing groupware systems. 16

17. 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

18. 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

19. Decision Support Systems
