Today I am reading chapter 7 of When the software smells like any of the following, it indicates that the software is corrupt.Rigidity: it is difficult to make changes to the system, because every change forces many other changes to the other part of the system.Vulnerability: changes to the system may cause problems in many areas that are conceptually irrelevant to the system and the changes.Strong: It is d

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

relationship between the Team and the customer is restricted by negotiation and cooperation, but more should be a relationship of cooperation and mutual assistance, so as to promote the success of the project; if everything is not a positive attitude of cooperation, but a negotiation standpoint, and the constraints in the contract will inevitably consume a lot of time and energy; therefore, although contract negotiation is also important, it is more important to promote the success of the proje

To continue the whole line of thinking, I will also involve some of the ways in which our team plans to sprint and what happens during the sprint, interspersed with answers to the questions you ask. First of all, I want to say that there is no such thing as agile without a plan. However, the plan in agile development is really different from the traditional

. IServer System session server interface, which is defined as follows: IServer is the server end of a system session. It defines the server name, location information, and session set established on the server in the interface. One to N sessions can be established on an iServer, that is to say, the server can communicate with N clients simultaneously. Iclient System session customer interface, which is defined as follows: Iclient is a client for system sessions. It defines the

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

This article is an architectural supplement to the introduction of the agileeas. NET application development platform and the agile parallel development method of agileeas. net. It is used to explain the architectural design ideas of the agileeas. NET platform. Speaking of the system architecture, I cannot give a definite definition of the system architecture.

client program asks for a change to the Fat class, it affects all other client programs. Therefore, client programs should rely solely on the methods they actually invoke. This can be achieved by decomposing the fat-like interface into multiple client-specific interfaces. Each client-specific interface declares only those functions that are called by its specific client or client group. The Fat class can then inherit all the client-specific interfaces and implement them. This relieves the depen

It stayed quiet, imposing its statutes on those objects without their permission or knowledge.ConclusionIf the statute covers a wide range and is visible, then the facade model can be used to apply the statute from above. On the other hand, if the scope of the statute design is small and freely customizable, then the mediator model is a better choice. The facade pattern is usually the agreed attention point. Everyone agrees to use the facad

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
