At present, "Multi combination + differentiated management " has become a effective commercial expansion path of development. According to reporter statistics, including the Parkson shopping center, Guiyou Plaza, Blue Island, Cuiwei Plaza, Xidan shopping mall, Dangdai shopping mall , Wangfujing department store ,展开更多

This paper discusses the DB/ODS/DW (traditional database/operational data store/data warehouse) architecture, data granularity and data partition in the data warehouse, describes the data model, and presents the client/server platform model.展开更多
