Historical Perspective n n n 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 n Foundational Concepts, n Information Technologies, and n Business Applications
Foundational Concepts n Chapters 1 and 2 n n n Components of Information Systems Types of Information Systems Roles they play Attributes of Information Competitive Strategy concepts
Information Technologies n n n We are concentrating on Databases Chapter 5 We are NOT covering software, hardware, and network technologies. If you are interested in these topics take n n CSIS-010 Introductory course CSIS-116 Advanced course
Business Applications n n 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 n 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 n 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 n n n 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) n n n Supports Operations Updates Operational Databases Examples: n n ATM Machine System – Banking Transactions Cash Register System – Point of Sale Transactions Accounting System – Checking Account Transactions Even Pay-per-view or On. Demand is a TPS
Process Control Systems (PCS) n n n Supports Operations Monitor and Control Industrial/Manufacturing Process Examples: n n n Petroleum Refining Power Generation Automobile Manufacturing
Enterprise Collaboration Systems (ECS) n n n Supports Operations (Surprised? ) Teamwork, communication, and collaboration Examples: n n n n E-mail Chat Video Conferencing Calendaring Journaling Workflow File Sharing
Management Information System (MIS) n n Supports Management (duh? ) Analysis & Reporting Charts, Graphs, Summary Tools Examples: n n n SCT Banner – Managing College Information (Siena uses it) Spreadsheet (Excel) – One of the first and most basic Oracle's Corporate Performance Management
