7 Three Main Categories of Information Systems 1. Operational-level systems 2. Management-level systems 3. Strategic-level systems

8 1. Transaction Processing Systems (TPS) 2. Management Information Systems (MIS) 3. Decision-Support Systems (DSS) 4. Executive-Support Systems (ESS) Four Major Types of Systems

10 Transaction Processing Systems (TPS) Basic business systems that serve the organization’s operational level Input: Transactions, events Processing: Sorting, listing, merging, updating Output: Detailed reports, lists, summaries Users: Operations personnel, supervisors

12 Typical applications of TPS

13 Management Information Systems (MIS) Serve management level; provide reports and access to company data Input: Summary transaction data, high-volume data, simple models Processing: Routine reports, simple models, low-level analysis Output: Summary and exception reports Users: Middle managers Four Major Types of Systems

14 How management information systems obtain their data from the organization’s TPS

16 Decision-Support Systems (DSS) Serve management level with data analysis for making decisions Input: Low-volume data or massive databases, analytic models, and data analysis tools Processing: Interactive, simulations, analysis Output: Special reports, decision analyses, responses to queries Users: Professionals, staff managers

17 Voyage-estimating decision-support system

18 Executive Support Systems (ESS) Provide communications and computing environment that serves the organization’s strategic level Input: External and internal aggregate data Processing: Graphics, simulations, interactive Output: Projections, responses to queries Users: Senior Managers
