Techopedia Explains Program Layer

Program layers can be though of as independent functional parts of an application. For example, a user interface (UI) layer, a business logic layer, and a database layer. Each of these layers can be implemented by different development teams without affecting other layers’ functionality.

By dealing with the relevant functions and data from the program layers just above and below it, the combined tasks can give the output expected of the overall system.
