A software architecture is the foundation on which an application is built. It is the blueprint of a software system and can be used to create, modify, and evolve a program or website. It defines how the program is designed, how it is built, and how all the parts fit together. The elements and relationships of the software architecture are responsible for the functions and processes that run in a program or website.
In a very general sense, software architecture describes how the program structure, including its objects, data structures, and algorithms, is designed to meet the needs of end users.
The goal of software architecture is to design a software system so that it can be understood, developed, and maintained by others in the future.
