. Developers choose to feel comfortable with their tasks and maintain high quality of work.Managers always get data at each iteration. They use this data to control and manage projects. They don't have to impose, threaten, or plead with developers to express arbitrary, unrealistic goals.It sounds like a nice, relaxing thing, but it's not. Using the data generated by the stakeholders is not always satisfactory, especially when it is just beginning. The use of
I have always been interested in some methods and principles of Agile Software Development and have many ideas. However, because I have little work to use and no one can communicate with each other, all those ideas only exist at the theoretical level, I hope to share these theoretical knowledge with you in your work or practice, but I am not very familiar with th
Thinking Paradigm leads to many obstacles in learning English. Therefore, after reading a large number of English books, you may find that Chinese statements are strange when reading Chinese. Even Chinese statements cannot be written in the future. At least I feel like this now. So the paradigm is actually a way of thinking.
In the previous development paradigm that adopted database priority, we need to switch to the object-oriented paradigm in t
well as the ORM code based on the Division class and the interface-driven Dal solution and project, we need to explain that one problem is the division class. In application development, our database operations are not only simple operations such as reading, updating, adding, and deleting, but also complicated database processing that works with the business logic in the Dal layer. This requiresProgramThe member modifies the generated code, which rai
I released an Online Demo Based on activexform/smartclient a few days ago. In activexform and/smartwin, we tried to demonstrate agileeas in two ways. net in winform development technology, today I am releasing a program based on agileas..

This online demonstration is based on agileeas. net project, I will show it with his consent, because the project time is tight during
What is Agile development?Agile Development (development) is a human-centric, iterative, and progressive approach to development. How do you understand it? First, we have to understand that it is not a technology, it is a

At this point, the newly created superclass might be an abstract class.The OCP is at the heart of many of Ood's claims. If this principle is applied effectively, the application will be more maintainable, reusable, and robust. LSP is one of the main principles that makes OCP known as possible.

environments, the "best method" is constantly changing and must be analyzed based on specific conditions..
Of course, there is another extreme opposite. I think that any method is not a good method, so I would rather follow the stream or talk about it later than pursue the universal value in this case. This will cause a lot of waste and mistakes, because when the "specific scenario" comes, without prior thinking and accumulation, I often feel unable to start. Therefore,For a specific environmen
The methodology is methodology in English. The programming methodology should refer to a complete set of methods, processes, rules, practices, and technologies for software development. However, the methodology we generally mention focuses on projects, processes, and personnel. The methodology proposed by Alistair Cockburn, author of agile
In the previous article, the plug-in interface IModule of AgileEAS. NET introduced the basic contract meaning of the plug-in, that is, the interface. This article will provide the definition of another module plug-in, using the property tag plug-in.
We have defined the ModuleAttribute attribute:
ModuleAttribute //
And ModuleRunAttribute attributes
ModuleRunAttribute ///
We only need to mark ModuleAttributes on the class of the module plug-in we want to public, and add ModuleRunAttribute on t

Of course, I saw some spams and thought of some things. Here I will record them and share them with you.

14.5 ConclusionUML is a tool, not the end result. As a tool, it can help you to think and communicate the design. If you use it sparingly, it will bring you great benefits. If used excessively, it will waste you a lot of time. When using UML, less is better.Excerpt from: "Agile Software
customers and users as frequently as possible to receive feedback from them.
Summary:
In many aspects, OCP is the core of object-oriented design. Following this principle can bring about the great benefits that object-oriented technology claims (flexibility, reusability, and maintainability ). However, it does not mean that we follow this principle as long as we use an object-oriented speech. It is not a good concern to abstract every part of the application. The correct approach is that devel

run, the faster you will find any deviations from those tests. If you can run all the tests multiple times a day, the system will not expire for more than a few minutes. This is a reasonable goal. We will never allow the system to regress. Once it is working at a specific level, it must not be reversed to a slightly lower level.However, validation is only one of the benefits of writing tests. Both unit and acceptance tests are a form of documentation. Such a document can be compiled and execute

and cannot be overused. If a class has hundreds of different interfaces, some of which are separated according to the client program, others are separated by version, then the class is hard to figure out, and this kind of hard-thinking is very frightening.12.5 ConclusionFat classes can cause unhealthy and harmful coupling relationships between their client programs. When a client program asks for a change to the Fat class, it affects all other client programs. Therefore, client programs should
following code: Public class base{ publicvirtualvoid f () {/*some code* / }}publicclass derived:base{ publicoverride void f () {}}The function f is implemented in base. However, in derived, the function f is degenerate. Perhaps, derived programmers think that function f is useless in derived. Unfortunately, base users do not know that they should not call F, so there is a substitution violation.The existence of degenerate functions in degenerate classes does not always mean that the LS
