The structure diagram proposed by Yourdon is another powerful tool for software structure design. A structure diagram is similar to a hierarchy diagram, and is also a graphical tool for describing software structures, in which a box represents a module with the name or main function of the module; the arrow (or line) between the boxes represents the calling relationship of the module. Because the formula is

On one occasion, I turned on the TV to look around and accidentally caught a war movie. Thousands of communist fighters set up ladders to break a fortress. But the enemy on the tower was putting up a desperate battle to intercept our attack. Both casualties are very heavy, but the city is unable to attack. Seeing that the rest of us are not many, suddenly I do not know from where to open a tank, two guns will be opened the gate. Our troops took advantage of the city and wiped out all the enemies

The factors that determine the maintainability of the software are:1) comprehensible 2) testability 3) modifiable 4) Portability 5) reusabilityWhat measures should be taken:1) Improved accessibility: Modular • Detailed design documentation • Structured design • Documentation within the program and good high-level programming language2) Improved testability: Good documentation is essential for diagnostics and testing, and

Thank you for your help from Baidu's IT community, Workaround for Ubuntu Software Center software disappears due to a software installation failure: Look for Baidu, some say, use command: sudo apt-get install Software-center Then, use the command: sudo apt-get Install XXX Then, use the command:

ScienceIt refers to the data structure and algorithm, Computing Theory-Theoretical Level TechnologyIt mainly includes: programming languages, operating systems, and other specific technologies-Technical Level EngineeringIncluding: software architecture, development documentation, project management, various tests, etc-Management Layer Quotations: Software always has bugs, no one knows where it will be

First, the preparatory work: Download and install the Absolute uninstaller Software (note: When installing, please choose simple Chinese, otherwise it is the English interface). Second, the operation steps: 1, open Absolute uninstaller software, click "Edit"-Automatically find invalid items, you can automatically find invalid software and invalid icon, etc.

. Programmers can analyze the types and quantities of software errors to find out the location and cause of errors, so as to avoid the same errors in future programming and accumulate programming experience, improve programming capability. Misunderstanding 6: do less test when project progress is tight, and do more test when time is rich This is a manifestation of the absence of emphasis on software testing

conversion capabilities. For example, a new data format or file format may be defined after the software is upgraded, which involves supporting and updating the original format, and whether the original user record is still available in the new format. In addition, you need to test the integrity and correctness of the data during the conversion process. (5) Compatibility test of software and hardware coord

consider the use of engineering methods and engineering approaches to develop and maintain software. We take the waterfall model and the spiral model two models as an example to discuss.1. Waterfall modelIn the traditional software engineering model, the Waterfall model is 1970 W. The earliest software development model proposed by Royce was a classic predictive

. Aggregation is a special case of association. It reflects the relationship between the whole and the part, that is, the relationship of "has. At this time, the whole and the part are separated. They can have their own lifecycles. Some can belong to multiple overall objects or share multiple overall objects, therefore, an aggregation relationship is also called a shared relationship. (For example, department and employee) 6. Composition is also a special case of association. It also reflects th

consists of three phases: 1, design 2, implementation: coding the source program according to the selected programming language. 3. Test 5. Maintenance:Maintenance includes four aspects: corrective maintenance: after the software is delivered and used, some hidden errors will inevitably be taken to the running stage due to incomplete and incomplete development and testing, these hidden errors are exposed in certain environments. 2. Adaptive maintenan

only a few important elements of success." If you master these elements, you will be successful. I think there are seven important elements to the shareware industry: decision, creation, promotion, sales, service, evaluation, and improvement. The better you master them, the more successful you will be. I found that most successful shareware authors noticed most or all of the seven-point features, while those who failed most tended to focus on only a few of them and ignored others.Here are seven

processes, such as human resources, Progress requirements, and development environment requirements, should also be considered. The architecture must support phased planning, and should be able to provide methods of development and completion in the phase planning. It should not rely on subsystems that cannot run independently. Find out the dependencies of various parts of the system to form a development

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. Software and

, most users are not computer professionals. If you use a line in requirement analysis, it will cause difficulties for users to understand. For example, if you want to create a bank's credit card system, you can describe the software requirement as follows: the Bank's card Department manages credit cards, and each credit card belongs to only one account. The credit card has a card number and balance. A credit card has multiple transaction records. Com
