The primary goal of the architecture is to identify requirements that affect the structure of the application.
It comes before the detailed design, coding, integration, and testing and after the domain analysis, requirements analysis, and risk analysis.
Guide the implementation tasks, including detailed design, coding, integration, and testing. To negotiate system requirements, and to set expectations with customers, marketing, and management personnel.Īct as a blueprint during the development process. The objectives of having a design plan are as follows − Software design provides a design plan that describes the elements of a system, how they fit, and work together to fulfill the requirement of the system. Selection of structural elements and their interfaces by which the system is composed.īehavior as specified in collaborations among those elements.Ĭomposition of these structural and behavioral elements into large subsystem.Īrchitectural decisions align with business objectives.Īrchitectural styles guide the organization. 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.
