Differences between Software Design and Software Architecture Last Updated : 13 Aug, 2024 Comments Improve Suggest changes Like Article Like Report Software design and software architecture, though closely related, serve different purposes in system development. Software design focuses on the detailed implementation of individual components and their interactions, guiding how the code is structured and written. In contrast, software architecture deals with the high-level organization and framework of the entire system, defining overall structure and principles. Understanding these distinctions helps ensure that both the design and architecture align with project goals, leading to more robust and maintainable systems. Differences between Software Design and Software ArchitectureImportant Topics for Software Design vs. Software ArchitectureWhat is Software Design?What is Software Architecture? Software Design vs. Software ArchitectureFrequently Asked Questions on Software Design vs. Software ArchitectureWhat is Software Design?Software design refers to the process of creating a specification of software artifacts that will help developers implement the software. It is about designing individual modules/components means it defines what is module is performing, the classes, functions, and their usages, etc. It is considered one of the initial phases of the Software Development Life Cycle (SDLC). The software design process establishes the best possible design plan to implement the system. It mainly focuses on the internal components of the system and their interaction with each other. What is Software Architecture? Software architecture refers to the fundamental structure or the process of creating the high-level structure of a software system. Initially, software architecture is created, and when it is agreed then that software design is carried out. In software architecture, the solution is structured in such a way that it meets technical and operational requirementsDuring structuring application quality, maintenance, performance, and overall success all things are kept in mind as ultimately software architecture impacts all these things at last.
