Intention Transform the interface of a class into another interface that the client expects, so that the two classes that do not match the original interface can work together. Scene Suppose that the client program for the network game is divided

Intention Define a factory interface that creates product objects and defer actual creation to subclasses. Scene Last time, we used abstract factories to solve the problem of producing a set of products, but we used each scene as a concrete

Beginning with this section, I will begin to experience dlinq with all of you. We have prepared the database before, and also made a preliminary understanding of the relationship between the database. What is the relationship between data and

A Web Services Overview: Web services are a new branch of Web applications that are self-contained, self-describing, modular, and can be published, positioned, and invoked via the Web. Web services can perform any function from simple requests to

A slightly more complex program typically has two or more forms. Sometimes in programming, data is passed not only in the same form, but also between forms, which are passed between the main form and the data from the form. Starting with this
