Bring your book to class.
What is an Information System
Organized combination of
1. Hardware
2. Software
3. Communications Networks
4. Data
5. People
Computer Hardware Technologies

Examples






Dell PowerEdge 2600 File Server
Apple PowerBook G4
Sony LCD Flat Panel Monitor
iPod
IDAutomation USB Barcode Scanner
RFID Chip


IBM DB2 8.2
Microsoft SQL Server 2000
Oracle Database 10g
MySQL
Data Mining Software
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.
Historical Perspective




Information Systems have
been around a long time.
People have always been
the backbone of an IS
The only thing that’s
changed in the complexity
of the information
and the complexity of the
technology.
Historical Perspective



Previous to computers,
telephones were probably the
biggest innovation that
improved information systems.
Previous to telephones, Paper
was the big innovation.
What will be the next big
thing?
What will we learn?
In this course, we will
concentrate on
 Foundational Concepts,
 Information Technologies,
and
 Business Applications
Foundational Concepts

Chapters 1 and 2





Components of Information Systems
Types of Information Systems
Roles they play
Attributes of Information
Competitive Strategy concepts
Information Technologies



We are concentrating on Databases
Chapter 5
We are NOT covering software, hardware,
and network technologies.
If you are interested in these topics take


CSIS-010 Introductory course
CSIS-116 Advanced course
Business Applications




Chapter 7, 8, 9, and 10
How are information systems used?
Most important aspect of this course
Understanding how an information system
can support decision making and give a
company a competitive advantage is not
trivial.
What we won’t learn



We won’t learn how Information Systems
are developed?
This is important but beyond the scope of
this course. Take CSIS-116.
We will briefly cover some challenges
involved in managing information
technology, but not in great detail. Think
about an MBA this material interests you.
Information Systems Serve 3 Roles

IS can support 3 different level in business
Role of IS has evolved over time
Role of IS has evolved over time
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.
Types of Information Systems
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
Process Control Systems (PCS)



Supports Operations
Monitor and Control
Industrial/Manufacturing Process
Examples:



Petroleum Refining
Power Generation
Automobile Manufacturing
Enterprise Collaboration Systems (ECS)



Supports Operations (Surprised?)
Teamwork, communication, and collaboration
Examples:







E-mail
Chat
Video Conferencing
Calendaring
Journaling
Workflow
File Sharing
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
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.
Executive Information Systems




Supports high-level strategic management
Provides critical info from other systems (MIS
and DSS).
Typically integrates external information such
as economic developments and news about
related markets and competitors.
Helps strategic decision making, not necessarily
tactical.


Tactical – doing things right
Strategic – doing the right things
