【Abstract】 With the internet technology being applied in PDM system in a more deepgoing way,the distributed PDM system is required to follow certain stanard and existent application systems are required to be integrated.In this paper,the Client/Server and multi layer system structure were analyzed and compared in the light for disadvantages of Client/Server system applied in the distributed PDM system.The advantage of multi layer system structure in the distrbuted PDM system was explained.Furthermore,the key technology of exploiting multi layer system structure with Delphi5 was introduced.更多还原
