Final answer:
The question doesn't match the options provided as it concerns the combination of a database and the application programs on top of a DBMS, none of which are Database schema, Database instance, Database query, or Database view. These terms represent specific concepts or components within a database system.
Step-by-step explanation:
The question refers to the different components that make up a database system, which includes both the stored data and the software used to manage and query that data. None of the options provided (a. Database schema b. Database instance c. Database query d. Database view) specifically refers to the combination of the database and the application programs developed on top of the DBMS (Database Management System). These options represent different concepts within the study of databases:
- Database schema: The structure that defines the organization of data within the database, including the tables, fields, relationships, views, indexes, and other elements.
- Database instance: A specific state of the database at a particular point in time, which includes the actual data and operational state.
- Database query: An operation or set of operations designed to retrieve specific information from a database based on certain criteria.
- Database view: A virtual table that is the result of a particular query and does not necessarily exist as stored data within the database.
To talk about the application programs that interact with the DBMS, we rather refer to database applications or software applications built to work with a DBMS.
