The embodiment of the invention discloses a data processing model building method and a data screening method based on a data processing model.The technical problems that according to existing electronic commerce, in the trading process, when large-scale marketing is needed at the platform end of electronic commerce, user data need to be extracted in a targeted mode, precision marketing is convenient, however, the existing data size is excessive large, errors are likely to be generated in the user data extracting process, and therefore efficiency is low are solved.The data processing model building method comprises the steps of building a fact table and at least one dimension table, wherein the fact table comprises a main fact table and an auxiliary fact table; relating the dimension table to the fact table to form a star-type model structure; relating the fact table through the multi-dimensional space data related structure in the dimension table to form a multi-layer star-type model structure.
Description
technical field [0001] The invention relates to the field of big data technology, in particular to a method for establishing a data processing model and a data screening method based on the data processing model. Background technique [0002] Big data is just a manifestation or characteristic of the Internet at the present stage. There is no need to myth it or maintain awe of it. Against the background of technological innovation represented by cloud computing, these data are difficult to collect and use. Big data is beginning to be easily utilized. Through continuous innovation in all walks of life, big data will gradually create more value for human beings. [0003] E-commerce is a commercial activity centered on commodity exchange by means of information network technology; it can also be understood as electronic transactions on the Internet (Internet), intranet (Intranet) and value-added network (VAN, Value Added Network). The activities of conducting trading activities...
