Four data acquisition methods for big data companies_Data Analyst Exam

For all the Internet companies that claim to be involved in big data, you can judge their prospects and value from two aspects, one is whether there is a stable source of data, and the other is whether there is a sustained ability to realize, which includes the accumulation of experience in the use of data understanding. The development of companies involved in big data in the Internet era as a spring, in addition to the giant Baidu, Tencent and Alibaba, there are a number of not so long established, but the depth of the company. Such as state cloud data, sail soft and so on. But no matter how big the company, access to data is a very important foundation.

In terms of data acquisition, the big Internet companies due to their own user scale is huge, the user's own e-commerce transactions, social, search and other data to fully tap, already have a stable and secure data resources. Then for other big data companies, there are about four types of data acquisition methods:

First, the use of advertising alliance bidding trading platform. For example, you buy a search company from the advertising alliance advertising space 10,000 times to display, then basically the search company will give you 100,000 opportunities for you to pick, each opportunity actually contains a description of the customer's portrait. If you buy a larger volume, you can also accumulate a certain amount of data profile of Internet users, which may not be a real-time updated profile. This is why the user's search keywords are usually closely related to the recommended content of other sites' advertising space, essentially the search company indirectly makes the user search portrait data public by way of advertising alliances.

Second, the use of user cookie data. Cookies are information (.txt text files) that the server temporarily stores on the user's computer so that the server can use it to identify the computer. Internet sites can use cookies to track statistics on the habits of users visiting the site, such as what time to visit, which pages visited, in each web page of the stay time and so on. This means that the legal way a website can only view cookie information related to that website, only the illegal way or the browser manufacturer has the possibility to get all the cookie data of the customer. Really large websites have their own data processing methods, and do not rely on cookies, the real value of cookies should be in the case of no login, but also be able to identify the customer's identity, is when ever visited what content of the old user, rather than a simple tourist.

Third, the use of APP alliance. APP is an effective means of obtaining the user's mobile data, pre-built SDK plug-ins in the APP, the user will be able to use the APP content in a timely manner to summarize the information to the designated servers, in fact, the user does not have access to the APP can be informed of the user's terminal information, including how many apps installed, what kind of applications. A single APP user scale is limited, the amount of data is limited, but such as a data company will be built into its own SDK tens of thousands of hundreds of thousands of APP, access to the user terminal data and part of the behavioral data will also reach hundreds of millions of magnitude.

Fourth, strategic cooperation with companies with stable data sources. The data obtained in the above three ways have the defects of completeness and continuity, and the value of the data is limited.The BAT giants have a more sound value chain of their own, and the data realization channel is more complete, so they will not easily export data to cooperate with third parties (except for acquisition). The data of government agencies are either all free or confidential, so there will be no cooperation of a commercial nature. Has a complete Internet (including mobile Internet) channel data resources, while the means of realization and the ability to lack of operators, naturally become the preferred target of big data cooperation.
