How many layers does a typical application using a database management system have?
A typical application using a database management system typically has three layers:
-
Presentation layer: This is the user interface layer, where users interact with the application through forms, reports, and other graphical elements.
-
Application layer: This is the logic layer, where the business rules and calculations are implemented. It communicates with the presentation layer to receive user requests and with the database layer to retrieve or update data.
-
Database layer: This is the data storage layer, where the database management system (DBMS) is used to store and manage the data. The database layer communicates with the application layer to retrieve or update data as needed.
