The data mining (Data Mining) was excavates the concealment unknown from the mass datas, formerly, has the latent value knowledge to the decision-making the new technology. The data mining is devotes to the data analysis and the understanding, promulgates the data interior to contain the knowledge the technology, it will become one of future information technology application profitable targets. Are same like other new technical development courses, the data mining technology also must after the concept propose, the concept accepts, the widespread research and the exploration, gradually applies and stage and so on massive applications. Divides according to the data mining duty, has the following several kinds: The classification or the forecast model data mining, the data summarize, the data gathers kind, the connection rule discovery, the sequence pattern discovery, the dependent relations or the dependent model discovery, exceptionally with tendency discovery and so on. The connection rule excavation is in a data mining important constituent. It mainly is seeks assigns the data set 中项 between the interesting connection and the correlation relation. The most famous connection rule discovered the method is the Apriori algorithm which R.Agrawal proposed. The connection rule discovery may divide into two step. First step is iterates the recognition all frequent projects collection, the request frequent project collection support rate is not lower than the user hypothesis the minimum value; Second step is not lower than the user hypothesis from the frequent project centralism structure confidence level the minimum value rule. The recognition or the discovery all frequent projects collection is connected the rule discovery algorithm the core, also calculates the quantity most major part. This article mainly conducts the research on the connection rule analysis, including elementary theory and algorithmic analysis. The main work includes: The analysis connection rule classical algorithm, points out its good and bad points and the applicable scope; To classical algorithm: The Apriori algorithm programs the realization with C; Carries on the experiment with the many kinds of data sets to the algorithm, and has analyzed the experimental result. Finally above the algorithm will integrate in together, the compilation visible contact surface, has realized a small data mining system. Key word: Data mining; Gathers a kind of analysis; Connection analysis; Algorithm

从字面上讲，主是主人，客是宾客。引伸地说，主是主权者，统治者，支配者，主动者，先进者，进攻者，处于主导地位；客是依附者，被统治者，被支配者，被控制者，被动者，后随者，防守者，处于被主导地位。 Literally speaking, a host is the master, a visitor is the guest. To amplify this, the host is in a dominant position as the sovereign, the ruler, the dominator, the initiator, the precursor and the attacker; whereas the position of the guest is being dominated as the dependant, the governed, the under dog, the controlled, the passive, the follower and the defender. 反客为主，是处于被主导地位的客，夺取主导地位，替代原来的主，并把原来的主放到客的位置上，随意摆弄的做法。因此，它是一种换位法，或者说是夺位法。 ‘Changes from guest to host’ means the guest seizes the dominant position of the host, replaces the original host, puts him in the position of the guest and bandy about at will. So it is an interchange tactic or a usurping tactic. 现实生活中，拍马术或溜须术颇为盛行。拍马当然是为了骑上马，骑上了上司这种人马，便可以轻而易举地操纵上司，谋利取益了。这是一种现代反客为主术，不知那些宠幸拍马逢迎者的官员们是否想到了这一层。 看来，三十六计，精华与糟粕共存。正人君子，恐怕还得三思而行。 In real life, lackeys or hangers-on are common sights. The objective of a lackey of course is to be a jockey, riding on top of his superior and easily control him to fulfill his own self-interests. This is a modern form of ‘changes from guest to host’, I wonder whether those sycophant and bootlicking government officials realize this. It appears that essence and trash (或者用elite and scum) both exist in the thirty-six tricks. For real gentlemen, they’d better think twice before executing them. 微软公司：技术跟随战略 微软公司有意识地采取“技术跟随”的战略：紧盯着市场上任何新的技术动向，密切观察新技术对市场的潜在影响力，分析新技术与微软现有产品技术相结合可能产生的制高控制力。当少数新技术生存下来并被证实了巨大的潜在价值时，微软就毫不迟疑地跟随，并在很短的时间内开发出产品，或者干脆把原创者购买过来，并迅速占领市场。“技术跟随”战略的好处是，省去大量开发经费、人力、时间，最有效地利用全行业的创造智慧，避免了投资失误。事实上，创新注定是失败很多次才能有一次成功，企业要想得到如此巨大的利益，必须具备几个条件：有兼备先知先觉和后知后觉的技术人才；有雄厚的资本支撑；有观察市场的眼光和魄力。 Microsoft Company: Stratagem of ‘follow the technology’ Microsoft Company consciously implements the stratagem of ‘follow the technology’: keeping a close watch on the movement of any new technology in the market, observing keenly its potential impact to the market, analyzing the possible dominating control created by the integration of the new technology with the present product technology of Microsoft. When the great potential values of the limited surviving new technologies have been proven, Microsoft will follow suit without hesitation and develop the product in no time, or will simply buy over the original and quickly occupy the market. The advantages of “follow the technology” stratagem are the savings on development expenditures, manpower and time, the effective utilization of the creative intelligence of the whole industry and the avoidance of investment errors. As a matter of fact, innovation is destined to be the only success after numerous failures; corporations that want to harvest this enormous benefit must possess the following requisite conditions: foresighted and hind sighted technical talents, strong capital support and discerning vision and boldness for market observation.
