Why each option

This question tests knowledge of the Data Dictionary technique, which formally defines data elements and their attributes to ensure shared understanding when used alongside structural models like Class Diagrams.

AReviews

Reviews are a quality assurance technique used to inspect and validate requirements or deliverables, not to formally define data elements and their characteristics.

BData Mining

Data Mining is an analytical technique used to discover patterns within large datasets, not a documentation method for specifying data element definitions.

CGlossary

A Glossary defines business terms and vocabulary used across a project but does not provide the technical specifications of data elements such as data types, formats, and valid value ranges.

DData DictionaryCorrect

A Data Dictionary is the technique used to define data elements by documenting each element's name, data type, length, format, allowable values, and relationships - complementing a Class Diagram by providing detailed attribute-level specifications. It ensures all stakeholders have a precise, common understanding of each data element referenced in the structural model, reducing ambiguity about data definitions.
