正解:D
Explanation
A data dictionary is a technique that is used to define the data elements of a system or a domain. It provides detailed information about the attributes of each data element, such as name, description, type, format, length, range, default value, validation rules, relationships, and constraints. A data dictionary helps to ensure a common understanding of the data elements among the stakeholders and to maintain consistency and accuracy in the data usage and manipulation. A data dictionary can be used to complement a class diagram, which is a graphical representation of the classes and their associations in an object-oriented system or domain.
