Xia Xiu · Mini-micro Systems · 2004
After analyzing and comparing the necessity and various strategies of data transmission in distributed environment, this paper advances the relevant factors of data construction strategy and the operational data store model. The time active and passive transmission rules and non time transmission rules are introduced, and three executing strategies guided by these rules such as normal transmission, time transmission and background transmission are described in detail. With the combination of data warehouse and distributed data base, We believe that this technology can advance the functions of current distributed data base management system, and take an active effect for applying and popularizing the distributed data base technology.
