DBMS Function

A Database Management System (DBMS) handles storage, retrieval, and control of data in a Decision Support System (DSS).

Strategic Models

Models used by top management to plan the future direction of the organization.

DSS Intermediaries

Staff members act as connectors between the Management Support System (MSS) and the decision-maker (manager) in a DSS.

DSS Decision Types

DSS supports semi-structured and unstructured decisions, requiring a mix of predefined rules and judgment.
