An architectural model (in software) contains several diagrams representing static properties or dynamic (behavioral) properties of the software under design. [1] [2] [3] The diagrams represent different viewpoints of the system and the appropriate scope of analysis. The diagrams are created by using available standards in which the primary aim ...
Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. There are two fundamental laws in software architecture: [3] [4] Everything is a trade-off "Why is more important ...
Process view: The process view deals with the dynamic aspects of the system, explains the system processes and how they communicate, and focuses on the run time behavior of the system. The process view addresses concurrency, distribution, integrator, performance, and scalability, etc. UML diagrams to represent process view include the sequence ...
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 .
In software development, the V-model [2] represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape.
Modern software development processes are not restricted to the discrete ALM/SDLC steps managed by different teams using multiple tools from different locations. [citation needed] Real-time collaboration, access to the centralized data repository, cross-tool and cross-project visibility, better project monitoring and reporting are the key to developing quality software in less time.
Especially in the field of software engineering many tools (A4 Tool, CAME, ARIS), languages (ACME, Rapide, UML) and methods (DSDM, RUP, ISPL) are developed and extensively used. Also, the transition between the software engineers (step 3) and computer programmers (step 4) is already highly formalized by, for instance, object-oriented development.
As a design tool, they aid the programmer in dividing and conquering a large software problem, that is, recursively breaking a problem down into parts that are small enough to be understood by a human brain. The process is called top-down design, or functional decomposition. Programmers use a structure chart to build a program in a manner ...
