What is included in the description of each identifier in a data dictionary?

The description of each identifier in a data dictionary includes details such as the name and size of the variable. This information is crucial, as it helps developers understand what each variable represents and how much data it can hold. The name provides a reference to identify the variable within the code, making it easier for programmers to understand and utilize it correctly. The size of the variable indicates how much memory it occupies, which is important for optimizing resource usage and ensuring that the program can handle expected data sizes effectively.

While the other options provide specific types of information, they do not pertain directly to the identifiers themselves. The programming language used is relevant to the overall context of the software but does not describe individual identifiers. The purpose of the software relates to the project as a whole rather than specific variables. Version control history might track changes over time but does not describe the functionality or attributes of individual identifiers.
