Definitions the software architecture of a program or computing system is the structure or structures of the system which comprise the software components the externally visible properties of those components. Details on computer programming languages and environments, machines, packages, application. Software architecture is the conceptual glue that holds every phase of the project together for its many stakeholders. The architecture of a software system is a metaphor, analogous to the architecture of a building. In the construction document phase the architect and engineers finalize all the technical design and engineering including structural engineering and detailing, heating air conditioning and ventilation systems, plumbing, electrical, gas, energy calculations, and all products and materials are selected and scheduled. If you consider that a typical sdlc consists of requirements, design, development.
Several good answers, already, but let me make a few additional distinctions. Software architect is the one who only works in the architecture phase which is after the design step, is the highest technical job one can aim for. Among the more crucial elements of software architecture are technology choices, system topology, object modeling and api definition. In addition, it also helps them in decisionmaking and handling risks. It is the longest phase of the software development life cycle process. Development of each step directly associated with the testing phase. Phases of the software architecture development lifecycle. In the coding phase, tasks are divided into units or modules and assigned to the various developers. Simplexity uses a phase gate process, based on decades of experience and industry best practices, to guide its product development. In design, functional requirements are accomplished. In software development, the vmodel represents a development process that may be considered an extension of the waterfall model, and is an example of the more general vmodel.
