Detailed design stage: development of engineering descriptions of the concept. ©Ian Sommerville 2000 Software Engineering, 6th edition. , anything that might affect the kind of software that is produced; A requirement may be ©Ian Sommerville 2004 Software Engineering, 7th edition. e. ppt. ©Ian Sommerville 2000 Software Engineering, COMP201 Slide 3. Process of Design. Software Architecture. - see chapter 5. Approaches: Top down – start with the architecture To make each design decision, the software engineer uses: Example: architectural design decision to separate the user interface module from rest of system. Course Summary: Review of Software Engineering Requirements and Architecture result from a design process involving requirements allocation A requirement is a technical objective which is imposed upon the software, i. . Architectural Design Process. Chapter 10 Slide 5. 7. the user are paramount and where the user is involved in the design process; UI design always involves the development of prototype interfaces; See UI_design. We'll look at UML later. practices. Feasibility stage: identifying a set of feasible concepts for the design as a whole; Preliminary design stage: selection and development of the best concept. Software architecture. Krutchen, 1995. ©Ian Sommerville 2004 Software Engineering, 7th edition. Chapter 11 Slide 3. Interface design: Describe sub-system interfaces. For both design and documentation, you usually need to present multiple views of the software architecture. Rational Unified Process built around UML. The output of this design process is a description of the software It might show how a system is decomposed into modules, how the run-time processes interact or the different ways in which system components are distributed across a network. Software Engineering Roadmap: Chapter 6 Focus. Identify. Language: syntax, usually graphical, used to express design; Process: steps to take to create a design; Many processes, not a lot of agreement; General consensus has built around UML as a language. Architectural design context; System structuring models; System control models; Modular decomposition models; Domain-specific architectures The output of this process is the software architecture. Creation of the data design; Derivation of one or more representations of the architectural structure of the system Phases in the Design Process. Data structure design: Design data structures to hold problem data. Software architectural design is the design process for identifying the sub-systems that make up a system, and the framework for sub-system control (+ Chap 31, Service-oriented software engineering); (+ Chap 32, Aspect-oriented software development) Topics covered. The design process for identifying the sub-systems making up a system and the framework for sub-system control and communication is architectural design. Component design: Decompose sub-systems into components. To introduce architectural design and to discuss its importance; To explain why multiple models are required to document a software architecture; To describe types of A framework for satisfying requirements; Technical basis for design; Managerial basis for cost estimation & process management; Effective basis for reuse 17 Oct 2014 Architecture design in software engineering. Design is all about decisions. Engineering Design Process. Perform Detailed Design . Basic Steps. corporate. 4+1 Architectural View Model. Chapter 11 Slide 4. Chapter 6 Architectural design. Introduction; Paradigms Agile methods, Aspect-oriented design, Design analysis, Component-based design, Software architecture. Design Simple test: When is the user interface to an application designed in your favorite software process? A problem: we Foundations, Theory, and Practice. Architectural design: Identify sub-systems. Architecture Design Focuses on the decomposition of a system into components and the interaction between those components to satisfy functional and non functional requirements A software system can be viewed as a hierarchy of design decisions (design rules or contracts) Each level of the hierarchy has a set of design Implement. Develop Architecture. 4. Architectural Design Process • Basic Steps – Creation of the data design – Derivation of one or more representations of the architectural structure of the system – Analysis of alternative architectural styles to choose the one best suited to customer requirements Architectural Design. Chapter 11 Slide 6○ ○ ○ What is architectural design? The process Architectural design decisions; System organisation; Decomposition styles; Control styles; Reference architectures. Distributed Systems Architectures. The design process for identifying the sub-systems making up a system and the framework for sub-system Software architecture; Architectural styles; Domain-specific architectures. 23 Jul 2017 Chapter 11 Slide 5○ ○ ○ ○ ○ Topics covered Architectural design context System structuring models System control models Modular decomposition models Domain-specific architectures ©Ian Sommerville 2000 Software Engineering. Abstract specification: Specify sub-systems. It can be applied to the design of other systems; It represents a set of abstractions that enable software engineers to describe architecture in predictable ways. The design process for identifying the sub-systems making up a system and the framework for sub-system control and communication is architectural design; The output of this To introduce architectural design and to discuss its importance; To explain why multiple models are required to document a software architecture; To describe types The design process for identifying the sub-systems making up a system and the framework for sub-system control and communication is architectural design Chapter 9: Architecting and designing software
