Layered architecture and its challenges
The layered architecture is a software architecture approach where applications are organized as a set of components in multiple layers. Each layer contains multiple components addressing a specific area of concern, where each layer can only communicate with its associated underlying layer. This way of communication helps in avoiding cyclic dependencies in a layered architecture. The layered architecture does not specify the number of layers, but it's common to observe four layers (the presentation layer, business logic layer, data access layer, and the database layer) in most applications. The layered architecture helps organizations create different teams aligned with different technical capabilities while they build applications.
However, the ability to make changes in a layered architecture is a constraint due to the tight coupling between different layers. As applications grow, making changes becomes more time-consuming due to a...
