Question

Quizplus · Accepted Answer

A data dictionary is a repository that contains comprehensive information about a company's data, including meaning, relationships to other data, origin, usage, and format. It serves as a central store of metadata that is relied upon by developers, administrators, and users alike to understand and manage the data stored in a database. On the other hand, a relational schema is a database design that specifies the tables, columns, relationships, and constraints that compose a database. A logical schema, on the other hand, is a description of the data in a database that specifies what data is stored and how it can be accessed. Finally, a database is an organized collection of related data that is stored and accessed electronically. While all four concepts are crucial to database management, only the data dictionary satisfies the criteria outlined in the question.
