Apriori Algorithm In The Commercial Application Of Decision-making System

The information took the modern enterprise the precious resource, is occupying the more and more important status, becomes the scientific management the foundation, correct policy-making premise, valid regulative method. In the retail sales profession, along with the electronic commerce and the commercial POS system broad application, in the database has collected massively about the commodity sale situation data, provided thoroughly has understood the client demand information and the shopping behavior characteristic contingency for the merchant. But majority isomerism system, the application, the service flow as well as data pool framing application conditions oneself which leaves behind down by the past after cannot meet such need.This topic take the big business group decision support system project as a backing, through to retails the profession the background AND-OPERATION flow analysis, proposed the establishment based on the data warehouse retail sales decision support system, enables its to assist the head of undertaking to make the decision-making, by enhances enterprise own competitive power.First introduced the research background of the system, contents and significance, discusses data warehouses and online analytical processing application status in the industry. Apriori algorithm and then discuss the basic techniques and methods, with particular focus on the algorithm of data mining technology in the retail analysis and explanation.Next, interpreted the data warehouse basic principle, and to its system structure, the data organization, the development design carries on in detail elaborated. Introduced in the data warehouse performance history the data model design technology and the design procedure, related in detail the data to extract, the purification and the increase process.Third, the detailed elaboration from the data warehouse database, the multi-dimensional data set constructs the aspect to design based on the data warehouse retail sales profession decision support system process, and Apriori algorithm is applied to the system, and achieved good results.
