  1. 0 What is an Information System Organized combination of • Hardware • Software • Communications Networks • Data • People

  2. 0 Computer Hardware Technologies • Examples • Dell PowerEdge 2600 File Server • Apple iMac • Sony LCD Flat Panel Monitor • iPod • IDAutomation USB Barcode Scanner • RFID Chip

  3. 0 Computer Software Technology • Examples • Windows XP • Graphics Card Driver Software • PowerPoint • mySAP Customer Relationship Management • Peachtree Accounting • iTunes Software

  4. 0 Telecommunications Network Technologies • Examples • Ethernet • Netgear Wireless Router • Cable Modem • Cell Phone • WiFi, WiMax card • Bluetooth device

  5. 0 Data Resource Management Technologies • Examples • IBM DB2 8.2 • Microsoft SQL Server 2000 • Oracle Database 10g • MySQL • Data Mining Software

  6. 0 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.

  7. 0 Information Systems Serve 3 Roles • IS can support 3 different levels in business

  8. 0 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.

  9. 0 Types of Information Systems

  10. 0 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

  11. 0 Process Control Systems (PCS) • Supports Operations • Monitor and Control Industrial/Manufacturing Process • Examples: • Petroleum Refining • Power Generation • Automobile Manufacturing

  12. 0 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)

  13. 0 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

  14. 0 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.

  15. 0 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
