The first is Shanghai dragon, Shanghai dragon in the understanding of the process, encountered the "external links", while learning the external links and occasional "spider", suddenly received so much information, feel very magical, Shanghai dragon thing is not simple.

want to talk to you today about the word "spider". I believe that I am not the first to mention it, because I was, but I hope that my description can let more people understand this word, after all, many professional presentations are quite professional, because it was too professional, and make people feel unable to understand.

then, unified content included in a library, a library and orderly, and this is a good name "database" in the online world, the database principle I will not say more, here we mainly realize it is in a certain format or data record of things, "the spider crawling" use this dongdong. To tell you about the "spider", of course, is not our daily see spiders, it is a simple computer program, crawling is the process of implementation of the algorithm process (as saying, not simply the arithmetic process, its meaning is equivalent to the daily activities of a planning process, like recently) love Shanghai changed the search algorithm, but specifically how to change or to let people understand slowly.
