DSS
• A DSS is a methodology that supports decision-making.
• It is:– Flexible;– Adaptive;– Interactive;– GUI-based;– Iterative; and– Employs modeling.

Components of DSS
• Subsystems:– Data management
• Managed by DBMS
– Model management • Managed by MBMS
– User interface– Knowledge Management and
organizational knowledge base

Data Management Subsystem
• Components:– Database
– Database management system
– Data directory
– Query facility

Models
• Strategic– Supports top management decisions
• Tactical– Used primarily by middle management
to allocate resources
• Operational– Supports daily activities
• Analytical– Used to perform analysis of data

User Interface Management System
• GUI• Natural language processor• Interacts with model management
and data management subsystems• Examples
– Speech recognition– Display panel– Tactile interfaces– Gesture interface

Knowledge-Based Management System
• Expert or intelligent agent system component
• Complex problem solving
• Enhances operations of other components
• May consist of several systems
• Often text-oriented DSS
