It defines a structured solution to meet all the technical and operational requirements, while optimizing the common quality attributes like performance and security.įurther, it involves a set of significant decisions about the organization related to software development and each of these decisions can have a considerable impact on quality, maintainability, performance, and the overall success of the final product. It provides an abstraction to manage the system complexity and establish a communication and coordination mechanism among components. Software ArchitectureĪrchitecture serves as a blueprint for a system. In Design, functional requirements are accomplished. In Architecture, nonfunctional decisions are cast and separated by the functional requirements. We can segregate Software Architecture and Design into two distinct phases: Software Architecture and Software Design. Software architecture and design includes several contributory factors such as Business strategy, quality attributes, human dynamics, design, and IT environment. The architecture of a system describes its major components, their relationships (structures), and how they interact with each other.
