software architecture foundations theory and practice

Software evolutionThis chapter introduces the concepts and methods of software evolution, including the characteristics of software evolution, software maintenance activities, reverse engineering and re-engineering.Software maintenance is an inevitable process. Software main

The seventh chapter, the object-oriented analysis of the requirements analysis phase of the core is to produce an accurate, complete, consistent and verifiable system model, called the analysis model. 1. Analytical Concepts: Analysis classes and analysis activities, classes include boundary classes, control classes, and entity classes. 2. Identify the analysis class: usually need to understand the behavior inside the system, identify the boundary class, control class, entity class. 3. Define int

automatically have all the properties and services of the parent class. A message is a service request made by an object that typically contains information such as the object identity, service identity, input information, and response information that provides the service. An association is a static relationship between object properties that represent the dependencies between objects through the properties of the object. Aggregations are the constituent relationships between objects, that is,

Demand EngineeringThis chapter takes the object-oriented technology as the core, comprehensively, deeply and systematically introduces the tasks, processes, methods and tools of each stage of software development.Software requirements can be divided into business requirements, user requirements, system requirements, functional requirements and non-functional requirements and other types. Requirements engineering is the application of proven principles

Practice of one-time invoicing Software Architecture (I) -- Overview 1. Structure Based on experience, we can find that an interface is always one piece. Each piece contains some basic controls (such as buttons, text boxes, and date controls), as well as a grid control and tree control, if each block is called a region, it becomes an item. In this way, we can
