Organized combination of
1. Hardware
2. Software
3. Communications Networks
4. Data
5. People

7. People Technology 



People are the 5th component of an
Information System
Everyone forgets the importance of
people in an information system.
Example: End User, Data Entry Person,
Manager, Programmer, DB Administrator,
Cashier, Secretary, Professor.

8. Information Systems Serve 3 Roles

IS can support 3 different levels in business
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

9. Expanding Role of IS



Information Systems are being used in more
areas, especial at the strategic level.
At the same time, Information Systems are
expanding participation of
End Users (The Grunts)
Biggest advantages of IS:
Information can flow up
the pyramid faster and
more effectively.

10. Types of Information Systems
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

11. Transaction Processing System (TPS)



Supports Operations
Updates Operational Databases
Examples:




ATM Machine System – Banking Transactions
Cash Register System – Point of Sale Transactions
Accounting System – Checking Account Transactions
Even Pay-per-view or OnDemand is a TPS
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

12. Process Control Systems (PCS)



Supports Operations
Monitor and Control
Industrial/Manufacturing Process
Examples:



Petroleum Refining
Power Generation
Automobile Manufacturing
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

13. Enterprise Collaboration Systems (ECS)



Supports Operations (Surprised?)
Teamwork, communication, and collaboration
Examples:







E-mail
Chat
Video Conferencing
Calendaring
Journaling
Workflow
File Sharing (Kazaa, Morpheus, Limework, Napster)
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

14. Management Information System (MIS)




Supports Management (duh?)
Analysis & Reporting
Charts, Graphs, Summary Tools
Examples:



SCT Banner – Managing College Information (Siena
uses it)
Spreadsheet (Excel) – One of the first and most basic
Oracle's Corporate Performance Management
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

15. Decision Support System (DSS)



Support Management
What-if Analysis, Decision Modeling, Scenario
Building, Highly interactive, ad hoc.
Examples



Enterprise Decision Manager 2.0 Fair Isaac
Corporation
AIMMS 3.6
Most DSS’s are custom developed for specific
companies; very few out-of-the-box products.
Introduction to Computing (CS101 by Sir Ayaz Ilyas)

16. Executive Information Systems (EIS)




Supports high-level strategic management
Provides critical info from other systems (MIS and DSS).
Portal Concept: one place with links to all information
EIS’s integrate external information such as economic
developments and news about related markets and
competitors. Helps strategic decision making, not
necessarily tactical.


Tactical – doing things the right way right
Strategic – doing the right things
