N-Layer architecture overview

N-Layer (or Multi-Tier) architecture is a software architectural pattern where responsibilities are separated into distinct logical layers. This promotes separation of concerns, making the application easier to maintain, scale, and test.

1. Presentation Layer (UI)

The top-most level of the application. Its primary responsibility is to handle the interaction between the user and the software.
