What Is Software Architecture?

Software architecture is the defining and structuring of a solution that meets technical and operational requirements. Software architecture optimizes attributes involving a series of decisions, such as security, performance, and manageability. These decisions ultimately impact application quality, maintenance, performance, and overall success.

Software Architecture Explained

Software architecture is a structured framework used to conceptualize software elements, relationships, and properties. This term also references software architecture documentation, which facilitates stakeholder communication while documenting early and high-level decisions regarding design and design component and pattern reuse for different projects. The software architecture process works through the abstraction and separation of these concerns to reduce complexity.

Architecture Description Language (ADL) describes software architecture. Various organizations develop different ADLs. Common ADL elements are connectors, components and configuration.

Software architecture serves as the blueprint for both the system and the project developing it, defining the work assignments that must be carried out by design and implementation teams. The architecture is the primary carrier of system qualities such as performance, modifiability, and security, none of which can be achieved without a unifying architectural vision. Architecture is an artifact for early analysis to make sure that a design approach will yield an acceptable system. By building a capable architecture, you can identify design risks and mitigate them early in the development process.

Software Architecture Methods

  • Capture architecturally significant requirements by analyzing the business drivers, system context, and factors that system stakeholders deem critical to success. There are two methods to identify crucial nonfunctional quality attributes of the system and also clarify system requirements. They are the Quality Attribute Workshop and the Mission Thread Workshop.
  • Design an architecture by developing architectural structures and coordination strategies that satisfy requirements. TheĀ  Attribute-Driven Design method helps organizations iteratively design effective architectures.
  • Evaluate the architecture by determining its ability to support the quality attributes that meet an organization’s business and mission goals. The Architecture Tradeoff Analysis Method (ATAM) and incremental design-review practices help organizations. This is in gaining early and ongoing insight into their software architectures.
  • Document the architecture in sufficient detail and an easily accessible form. Hence, to facilitate communication with developers and other stakeholders and to support analysis. Our Views and Beyond approach captures multiple architecture views, each addressing the concerns of particular stakeholders. The SEI also helped develop the Architecture Analysis and Design Language (AADL). Likewise, a domain-specific architecture modelling language used for safety-critical systems, and the Open Source AADL Tool Environment (OSATE). AADL and OSATE are used to analyze the performance, security, and safety of real-time systems.

What Is Software Architecture

In Conclusion

Software architecture is defined as the structure and organization by which modern system components and subsystems interact to form systems. And the properties of systems that can best be designed and likewise analyzed at the system level. Software architecture began to assume a strategic role. Hence, for managing the development of software systems near the end of the microcomputer era.
