MANAGEMENT INFORMATION SYSTEM
Data: Raw fact with no knowledge of relationship (unprocessed data), symbols. Example: records of customer
Information: Processed data, useful to take decisions. (Data + Meaning)
Knowledge: Ability to understand information, to make predictions and to give judgments. (Data + Meaning + Purpose)
Wisdom: Deep understanding (Data + Meaning + Purpose + Experience)
System: A group of interrelated components with clear boundary to achieve goal.
Information System: A set of interrelated components that collect, process store and distribute information. Examples: Online order system, Account management system, Railway reservation system.
Elements of Information System – People, Procedure, and Data.
Characteristics of Information – Accuracy, Relevancy, and Timeliness.
EVOLUTION OF INFORMATION SYSTEMS:
- The Era of Efficiency (1960): Doing the things right such as, Productivity gains, Cost savings, expanded processing capability, Cost/Benefit analysis, Return on Investment, Management Information Systems.
- The Era of Effectiveness (1975-80): Doing the right things such as, Client-server systems, End-User computing, Decision Support Systems, Executive Information Systems.
- The Era of Competitiveness (1980-95): Doing new things such as, strategic and market orientation, Organizational transformation, Strategic Information System
- The Era of E- Business (1995-today): Doing new things with the help of Business Information Systems.
TYPES OF INFORMATION SYSTEM
