Quizplus · Accepted Answer

The schema is the logical structure of a database that defines the tables, fields, relationships, and constraints within the database. The data dictionary contains information about the data within the database, including data types and relationships, but it does not define the overall logical structure. The database management system is the software that manages and provides access to the database, but it does not define the structure. The context diagram is a high-level diagram that shows the interactions between a system and its environment, and is not directly related to the structure of a database.
