Slippers and fathers - Web programmers programming environment and tasks
Feng Yucai once translated a story, and a city has a friend. A fat gyzykly, a thin amazing. At first, the fat man was playing. People are fat, the body is weak, and the body is not lost, and the male is angry. One time people are looked, and they are very belly, pretending that the fat man does not have someone; a certain fat man finds the old friend's thin child. Seeing the thin and thin bones, say: "Now everyone learning me, why don't you learn?" The thin man smiled: "Memorant, you will go." New Year's new saying: people are fat, asthm, sweating Incidental action, more fat, susceptible to vascular disease, have a hundred damage to no one. The thin and shaking becomes "the best weight of contemporary people", "the weight of the most in accordance with the times", "typical image" cloud cloud. This day, two friends met. The fat man is emotion: "I heard you soon, I will get thinned, now I am difficult to lose back!" The thin man shook his head: "Non! I don't know what the day is fat!"
■ WEB system working principle - Take a takeaway "Hello must be slaughtered, give me a white bone sperm package, address 123 Dongxin Road", Yan Yan squatted one through the phone, 1 minute, what you want later in the computer screen, " OK, you are eating! ", Fainting ... If the client requests HTML, the whole process is very simple, it is necessary to play the way to send the present food to the original. "Quiet" refers to the server that does not process the content after receiving the request. If the customer requests a dynamic page (PHP / ASP / ASP.NET / JSP), it will be able to send the client's request and data, press the HTML page to temporarily generate the HTML page, and send it back to the client. In the first two days, I saw a text in Sina Technology. It accused the problem of Dell sales model, and the big shredded linkage * scientifically combined traditional model and direct mode, there is a world IT giant's wind Caiyun, I want to start the brand on the motherboard The capacitor is fry into two contexts in front of my friends, a burst. Dell received the "zero stock" model produced after the order, its own emotion (China's terminal seller is unhappy), the traditional sales network of the link also supports itself step by step. If this world is all, it is very good! But the world will never wait, and the old horse told us very early. ■ Web programmer - Ten Almighty Athletes "ultimately, we realize that a good performance, interactive web application is dynamic server-side code and client code, and mixtures of static content." This requirement is Web The programs have the hardships of the programmer, but also to familiar with the static language (HTML) and client scripting language (JavaScript, Java Applet, etc.), but also to be familiar with the server-side language (Java, C #, etc.), of course, the database is more It is not less, hey, run jump, it is the same. Of course, some people can say teamwork, ha, haha, China has several bosses, willing to raise so many people, poor people, including me. The main purpose of the client program is to let the browser respond to part interface operation and can request data to the server, its role is to mitigate network traffic and server-side pressure, but unfortunately, some criminals are in the dark. I don't know if the sinful seeds on your machine are 372 *, so some users have such annoying client programs, actually disabled! The server-side program is based on the user request, extracts the data, generates an HTML page. Of course, it can also generate a client program (I always have a data exchange between VBScript and JavaScript) and send it to the client. Fathers and thin children are distributed calculated eternal topics, reasonable arrangement of client and server-side function assignments are important guarantees for excellent system performance. The advantage of B / S is that there is no need to worry about the client; the advantage of C / S is that the powerful interface interaction ability; RIA (RICH Internet Application) combines a technique of these two structural advantages, install a universal explanation at one time at the client After the device, the powerful interface interaction ability and the convenience do not need to deploy the specific client. For example, Microsoft's SmartClient, Avalon, Macromedia's Flex; Bindows based on JS; Ajax, etc. The client program seems to be the trend of this article, and this is popular today, and the fatches will pop.
