ARCHITECTURE WORD PROGRAM DIAGRAMS SOFTWARE

Things that people perceive as hard to change: since designing the architecture takes place at the beginning of a software system's lifecycle, the architect should focus on decisions that 'have to' be right the first time.

That which is fundamental to understanding a system in its environment.

The important stuff-whatever that is: this refers to the fact that software architects should concern themselves with those decisions that have high impact on the system and its stakeholders.Macroscopic system structure: this refers to architecture as a higher-level abstraction of a software system that consists of a collection of computational components together with connectors that describe the interaction between these components.Opinions vary as to the scope of software architectures: : 29–35 Software architecture activities Scope Additionally, to satisfy the need for reliability the choice could be made to have multiple redundant and independently produced copies of the program, and to run these copies on independent hardware while cross-checking results.ĭocumenting software architecture facilitates communication between stakeholders, captures early decisions about the high-level design, and allows reuse of design components between projects. Therefore, an appropriate real-time computing language would need to be chosen.

Software architecture choices include specific structural options from possibilities in the design of the software.įor example, the systems that controlled the Space Shuttle launch vehicle had the requirement of being very fast and very reliable. Software architecture is about making fundamental structural choices that are costly to change once implemented. Whilst application design focuses on the design of the processes and data supporting the required functionality (the services offered by the system), software architecture design focuses on designing the infrastructure within which application functionality can be realized and executed such that the functionality is provided in a way which meets the system's non-functional requirements. Software architecture design is commonly juxtaposed with software application design. It functions as the blueprints for the system and the development project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved. The architecture of a software system is a metaphor, analogous to the architecture of a building. Each structure comprises software elements, relations among them, and properties of both elements and relations. Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems.
