Architecture evolution is the process of maintaining and adapting an existing software architecture to meet changes in requirements and environment. As software architecture provides a fundamental structure of a software system, its evolution and maintenance would necessarily impact its fundamental structure.
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.
guide their work. Rule of thumb: know what it is you want to say, and whose work you intend to influence with it. Specific Set of Tradeoffs: The architecture tradeoff analysis method (ATAM) methodology describes a process whereby software architecture can be peer-reviewed for appropriateness. ATAM does this by starting with a basic notion ...
Software architecture pattern is a reusable, proven solution to a specific, recurring problem focused on architectural design challenges, which can be applied within various architectural styles. [ 1 ]
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
According to Pree, [8] software frameworks consist of frozen spots and hot spots. Frozen spots define the overall architecture of a software system, that is to say its basic components and the relationships between them. These remain unchanged (frozen) in any instantiation of the application framework.
