Network diagrams show processes (rectangles) and how they communicate with each other, either via state vector connections (diamonds) or via datastream connections (circles). In this stage, the functionality of the system is defined. Each entity becomes a process or program in the network diagram. External programs are later added to the ...
Structured analysis consists of interpreting the system concept (or real world situations) into data and control terminology represented by data flow diagrams. The flow of data and control from bubble to the data store to bubble can be difficult to track and the number of bubbles can increase. One approach is to first define events from the ...
These core architecture activities are performed iteratively and at different stages of the initial software development life-cycle, as well as over the evolution of a system. Architectural analysis is the process of understanding the environment in which a proposed system will operate and determining the requirements for the system. The input ...
Required logical data structure; Logical process model – includes dialogues and model for the update and inquiry processes; Stress & Bending moment. Stage 6 – Physical design. This is the final stage where all the logical specifications of the system are converted to descriptions of the system in terms of real hardware and software.
Network architecture. Network architecture is the design of a computer network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used. In telecommunication, the specification of a network ...
The Shlaer–Mellor method, also known as object-oriented systems analysis ( OOSA) or object-oriented analysis ( OOA) is an object-oriented software development methodology introduced by Sally Shlaer and Stephen Mellor in 1988. The method makes the documented analysis so precise that it is possible to implement the analysis model directly by ...
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. 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.
Software development. 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.
