The correct answer is: D. to enable the users to interact with the DSS.
A language system is a computer program that enables users to interact with a DSS (Decision Support System) using natural language. This means that users can enter their requests and questions in plain English, and the language system will translate them into a form that the DSS can understand. The DSS will then return its results in a format that the language system can translate back into plain English for the user.
A language system is a critical component of a DSS because it allows users to interact with the system in a way that is familiar and easy to use. This makes it possible for users to access the information and analysis that they need without having to learn a specialized language or software.
The other options are incorrect because:
- Option A is incorrect because the language system does not perform processing tasks. These tasks are performed by the DSS itself.
- Option B is incorrect because the language system does not provide artificial-intelligence capabilities to the DSS. These capabilities are provided by other components of the DSS, such as the knowledge base and the inference engine.
- Option C is incorrect because the language system does not provide data to the DSS. Data is provided by other components of the DSS, such as the database and the data model.
