Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it.

Case-based reasoning is a system of solving problems in engineering and artificial intelligence. Here, problem-solvers resolve problems based on past experiences.

For example, to repair a faulty computer, the repairman recalls a computer that such a similar case and applies the same reasoning in solving the current problem.

Therefore, the correct answer is case-based reasoning because, past problems are stored with keywords that will make it easier to solve new problems.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.

Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.
