What are the components and structure of the Decision Support System?

The structure of the Decision Support System

The Decision Support System is mainly composed of the following four components –
1. The database and the management of the database.
2. The modelbase and the management of the modelbase.
3. The hardware.
4. The user system interface.

Different components of the Decision Support System
1. Dialogue management
a. Consists of the three sub systems; namely the user interface, the dialogue control, the request translator.
b. The user interface sub system controls the physical user interface.
c. It also manages the appearance of the screen and also accepts the input from the user and then displays the results.
d. The user interface sub system is also responsible for checking the user commands for the correct syntax.
e. The dialogue control sub system is responsible for the maintenance of the processing context with the user.
f. The request translator helps in the translation of the user command into the actions for the model management or the data management components into such a pattern that can be easily understood by the user.

2. Model management
a. The command processor delivers those commands from the dialogue management components to either the model base management system or the mode execution system after receiving the commands from the dialogue management components.

3. Database management
a. Helps in the storage of the database.
b. Also helps in the manipulation of the database.
c. Works under the guidance of the either the model management component or the dialogue management component.
d. Helps in the maintenance of the interface with the data sources that are generally external to the Decision Support System.
