Video Description. Here is another nice book. Quality Attribute sum-up. Software architecture in practice / Len Bass, Paul Clements, Rick Kazman.—3rd ed. Quality Attributes. Software Architecture Topics Introduction to Architecture Quality Attributes •Availability •Interoperability •Modifiability •Performance •Security •Testability •Usability Other Quality Attributes Patterns and Tactics Architecture in Agile Projects Designing an Architecture Documenting Software Architectures Architecture and Business The award-winning and highly influential Software Architecture in Practice, Third Edition, has been substantially revised to reflect the latest developments in the field. Introduction • We are interested in how the architect achieves particular qualities • Our interest is in the tactics used by the architect to create a design using design patterns, architectural patterns, or architectural strategies • the tactics chosen will guide the architectural decisions. Architecture patterns describe the high-level structure and behavior of software systems as the solution to multiple system requirements, whereas tactics are design decisions that improve individual quality attribute concerns. Software archiecture lecture06 1. Software architecture focuses on the implementation that will solve a specific problem. Quality Attribute = Definition + Tactics + Scenarios. ... Attribute-Driven Design (ADD) is an approach to defining software architecture where decomposition is based on: A.) What is Software Architecture? @whereischarly. @whereischarly. These LiveLessons will provide you with practical, road-tested techniques and advice to help you become a software architect. ATAM. Software architectures provide the base for mastering the complexity of big software development projects. Interoperability is an attribute of the system or part of the system that is responsible for its operation and the transmission of data and its exchange with other external systems. 1.1 System and Software Architecture Modeling System Architecture can be defined as the set of principal design decisions taken for a system. 3. So the goal of modifiability is to make flexible systems that can handle change at the minimum cost. Modifiability is a design quality that can be supported by mechanisms throughout all the phases in the system life-cycle. In a real-world setting. Software Architecture in Practice, p.63. Designing Software Architecture ... Modifiability tactics 18 8.11.2011 Modifiability tactics. REliable,INtelligentand ScalableSystems’Group’(REINS) ShanghaiJiaoTongUniversity ... Modifiability Tactics- defer binding time • Our!modiHiability!scenarios!include!two!elements!that!are!not! Design Architecture. Software Architecture in Practice LiveLessons provides aspiring architects an overview to a broad range of methods, processes, and tools that are essential to managing the complexity of large-scale software. Availability Tactics, Modifiability Tactics, Performance Tactics, Security Tactics, Testability Tactics, Usability Tactics. 12 software architecture quality attributes Performance – shows the response of the system to performing certain actions for a certain period of time. Software Engineering Achieving Quality Attributes –Design Tactics A system design is a collection of design decisions Some respond to quality attributes, some to achieving functionality A tactic is a design decision to achieve a QA response Tactics are a building block of architecture patterns –more primitive/granular, proven Compare System Architecture and Software Architecture. Pattern and reference model. By using Contact mobile apps as a case study, the results show the MVVM architecture is good for testability, modifiability (cohesion level procedural), and performance (memory consumption).
