Explanation

Data Modeling Language Explanation

A data modeling language is designed to describe the structure, relationships, and meaning of data that is exchanged between systems - for example, XML Schema and JSON Schema define what fields exist, their data types, and how they relate to one another. Option B is incorrect because parsing procedures fall under protocol or processing specifications, not data modeling. Option C is incorrect because object-oriented programming frameworks are a software development concern, not a purpose of data modeling languages. Option D is incorrect because transcoding rules between text and binary formats are handled by encoding specifications (like Base64 or UTF-8 standards), which are separate from data modeling.

Memory Tip: Think of a data model as a blueprint or map - just as a blueprint describes the structure of a building (not how to build it or what tools to use), a data modeling language describes the structure and meaning of data (not how to process or encode it).
