Looking at the future of software and software engineering from the history of human development Abstract:Through the history of human history over thousands of years, we can see a clear evolution on the timeline. This context not only tells about the past development of mankind, but also points out the trend of human destiny.

. The description method of system requirement model: Structured English, visual model and formal method.Second, the demand engineering processGet the demand : Listen to the user's needs, analyze and organize the information obtained, and document the description.Requirement Analysis : Define the boundary of the system, establish the software prototype, analyze the requirement feasibility, prioritize the re

valueWhen predicting, we can find the result point by the sub-layer information, and take the probability matrix and the numerical matrix of the result point.class, module locationWhether ID3, C45 or C50, the predictive model of decision tree is the same tree structure, and the C45 decision tree is a kind of algorithm to construct decision tree. Therefore, in terms of naming, the predictive model is prefixed with no C45.The algorithm involves the following class distributions: Writing machine l

modification methods, all problems that occur in the first version will be reproduced one by one. Until someone makes up their minds and wants to fundamentally solve the problem, there will be the previous re-writing. Although a lot of effort has been made to re-develop a new version, every time we go back to the starting point and repeat our previous mistakes. This kind of effort is in vain. We often think of a better outcome, but in the end, we often make the same mistake again. So there is

1. Project Design The dominant idea of project design can be understood as two types: full design and simple design. Full Design refers to investigating various aspects of the software before writing specific code, analyzing detailed requirements, and compiling all development documents, after all the procedures are designed, write the code again. In other words, after all the plans are completed, we can see the final view and start the war again. Thi

It took me two nights to finish reading "software technology", which should be a non-technical computer book that I once again applauded after "programmer's Cultivation". Although it was just a waste of time, however, the problem solved my doubts. Software Engineering emphasizes the process of software development, whi

Demand EngineeringThe basic task is to determine the target and scope of the system, investigate the user's needs, analyze what the system must do, compile other relevant documents such as the Requirement Specification and Requirement Engineering Review. in addition, it also includes requirement change control, requirement risk control, and Basic Plan for the demand process. RequirementIt refers to the specifications that must be implemented by the s

First, the traditional software engineeringSince the 60 's, people have come to realize the fact that there is a "software crisis" in which software developers are troubled by issues such as the following: Software production does not meet the growing need Software
