Question

The question asks: The DBMS stores definitions of the data elements and their relationships in a:

First, identify the key concept: in database management systems, the repository that holds metadata about data elements, their attributes, data types, constraints, and how they relate to each other is called the data dictionary (also known as metadata catalog or system catalog). This repository is used by the DBMS to interpret and manage data definitions, implement schemas, and enforce integrity.

Since the provided answer field indicates the correct option as "c. data dictionary", we can affirm that the data dictionary is the conventional term for the repository that stores definitions of data elements and their relationships. It acts as a catalog of metadata that describes schemas, tables, columns, data types, constraints, indexes, and the relationships among data entities, enabling query optimization, schema management, and data governance.

Regarding the answer options: the JSON payload for answer_options is empty in this case, so there are no alternative choices to evaluate and compare. In a typical multiple-choice setup, you would compare each option to established database concepts:
- A data dictionary (or system catalog) contains metadata about database objects.
- Some distractors might refer to the data file, data log, or schema, but these do not correctly describe the repository of element definitions and relationships.
- The schema defines structure at a higher level, while the data dictionary catalogues the metadata, which is the more precise match for the question.

If you provide the actual list of answer options, I can walk through each one, explaining why the correct choice aligns with the data dictionary concept and why the other options are not appropriate descriptions for where the DBMS stores data element definitions and their relationships.
