agile software development principles patterns and practices

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

. Strict deadlines force you to make tough decisions without leaving long-standing issues behind.A fixed price means a betrayal of commitment.Let the guest team and the customer work together, truly in the current project to do the actual evaluation, by the customer control their function and budget.How to estimate project cost and time is another science.1. Proposed to build the system demo (to make the most important functional part), the completion of the first delivery should be no more than

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

Whether it is in activexform or smartclient mode, the interface effect is the same, because the same service plug-in module is used, all the requiredProgramSet. Demo account online. You can use three common accounts: demo1, demo2, and demo3. You can also directly use the James Administrator Account to log on to the demo. All accounts and passwords are demo.

Code is often corrupted. With the addition of one new feature, the structure of the Code gradually degrades when an error is handled. If you ignore this, this kind of degradation will eventually lead to tangled and difficult to maintain chaotic code. The XP (eXtreme Programming) team uses regular code refactoring to reverse this degradation. Refactoring does not change. A series of small modifications are made to improve the system structure on the premise of code behavior. Every transformati

Introduced: In agile software development, the speed of code generation is much higher than that of traditional waterfall. Because we have made the time more compact. How can so much code guarantee the quality of the code? Many people may think directly of static code detection tools. Yes, those are the ones that can define a code-checking rule to ensure the qua

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.

My application to the press last week was finally approved and the publishing contract was finalized. Spring 2: Principles and Practices of the Lightweight J2EE development framework is a book that explains spring design principles, I wrote several members of easyjf. Half completed in the early stage, and there is stil

Opening and closing principle OCP (Open for extension,closed for modification). The core idea of open and close principle is that an object is opened to expansion and closed to modification. In fact, the opening and closing principle means that changes to the class are made by adding code rather than altering the existing code. In other words, once the software developer writes out the code that can be run, it should not change it, but to ensure th

: Interface high cohesion is internally highly dependent and isolated as much as possible. That is, the method of internal declaration of an interface is related to a sub-module, and is required by this submodule. Interface design is limited: If you fully follow the principle of interface separation, there will be a problem, that is, the design of the interface will be less and less, so that the number of interface increases, the complexity of the system increased suddenly, rather than the
