software architecture foundations theory and practice

The 11th chapter, Software Evolution 11th chapter mainly talk about1, Software evolution characteristics, software maintenance is an inevitable process, software changes will lead to software degradation, the evolution of software

Formal methods in software engineeringThis chapter introduces the formal methods in software engineering, including sequential logic, Z language, Petri nets and so on.Software specifications are descriptions of software system objects, how objects are manipulated, and the behavior of objects. During the development and evolution of the system, the object, the nat

Errors are the properties of the software and cannot be changed. Testing is the inspection and evaluation of the quality of software products. The basic principles of software Testing: ① Software testing as early as possible, ② avoid checking their own programs, ③ test cases include reasonable input conditions and unre

should be straightforward, and good annotations are a refined bid and a clear presentation of design ideas.variable naming problem do not use your own prefix to name the variables and methods in the program. A good software code product should be able to be easily read by the tester, by the maintenance personnel easily modified.Memory anomaly Problems possible causes of memory anomalies, memory leak problems, pointer parameter problems, "wild pointer

Software Engineering--object-oriented analysis of theory, method and practiceDuring the requirements acquisition phase, developers focus on understanding the user and their usage needs. In the demand analysis phase, developers focus on understanding what the system needs to build, at the core of which is to produce an accurate, complete, consistent, and verifiable system model called an analytic model.The o

The Nineth Chapter, the software realization the nineth Chapter of the software implementation process includes code design, design review, code writing, code compilation and unit testing and other basic activities. Mainly speaking1 , programming language, language evolution and evolution;2 , Software Coding specification, the importance of writing specification

The beginning of the architecture design determines the survival of the software products. "A good beginning equals half success." The initial architectural design is also the most difficult, the need to investigate the situation of similar products and technical characteristics, to understand the current world of this product can provide theoretical support and technical platform support. Combined with th

Fifth Chapter mainly speaking 1. 2.The temporal logic introducesKripkeThe First order linear temporal logic is explained by the example of the queue and its operation and the Hanoi operation planning problem. The calculation tree logic is generallyCTLwith thectl*the general designation. 3.model detection is in the software systemKripkeunder the structure model, thectl*The correctness of the software nature

The Nineth chapter mainly talk about the normative code, first of all to have the appropriate blank line, pay attention to the branch alignment and indentation, naming rules: The name of the identifier should be intuitive, you can hope to understand the text, preferably in English words or their combination, the length of identifiers should meet the minimum length of the maximum information principle, Long English words should use some common and reasonable abbreviations or abbreviations of appl

The object-oriented analysis model has a functional model (use case, Scene), Analytical object model (class diagram, object graph), dynamic model (state diagram, sequence diagram). The identification analysis class provides a heuristic approach to discovering bounded classes, control classes, and entity classes, but using this approach still requires a lot of experience from developers. Boundary classes are information from participants, which can be used by entity classes and control classes. T

, consisting of three elements of processes, methodologies, and tools. Computer aided software Engineering is a set of tools and methods, case system can be divided into 3 levels of tools, workbench and environment. The purpose of the SWEBOK project is to provide a consistent recognition of the boundaries of software engineering disciplines and to provide guidance for supporting the knowledge system in this

document is divided into two categories: the test plan and the test analysis report. Software products typically require unit testing, integration testing, validation testing, and system testing before they are delivered to use. The debugging of software has simple debugging, inductive debugging, deduction debugging and backtracking debugging. Black-Box testing is also known as functional testing, and it i
