Database

an organized collection of structured information or data, typically stored electronically in a computer system.

Database Management System (DBMS)

serves as an interface between the database and its end-users or programs, allowing users to retrieve, update, and manage how the information is organized and optimized.

Database Application

a set of one or more computer programs that serves as an intermediary between the user and the DBMS.

Users

Naive users are unsophisticated users who interact with the systems by using predefined user interfaces, such as web or mobile applications.

Application programmers are computer professionals who write application programs.

Sophisticated users interact with the system without writing programs. Instead, they form their requests either using a database query language.
