Pdm System Based On Distributed Database Technology

Nowadays,IT industry technology is constantly changing, with no exception for database. With the occurene of new application,the development of network technology and prompting popularity,database is faced with many new problems and challenge,one of which is that the alteration of operating environment bring a series of proplems.At present ,database oprerationg environments are not integrated system of single database but distributed environment based on network.therefore,it has academic and realistic requirement that how to implement integrated questions of distrubited system,arrive at centralized management and share with data,meanwhile make the area disperse hindered by system.The study of distributed involves the study of distributed processing technology,net work technology and database study,which must be related to solution on some real existent problems.This paper mainly resolves distributed proplem of distributd PDM system , explores a set of schemes of feasible dirtributed database system,and solve problem of production data management in enterprise.main contents as follow:1.Studying duplicating proplem of distributed database sintem,and giving a general model.2.discussing about the procedure management of distributed system,bringing forward a set of integrated designing theme.3.in light of the rule of multi-CPU dispensation,giving several algorithm of CPU dispensation .4.deeply studying integrated designing motheds of distributed PDM system,and giving a set of integrated themes.5.giving a theme which enterprises implement PDM system.and giving a example. .
