Abstract:

A digital compus requires the intergration of  the data of application systems.As for the Ecard system as an important part of the digital compus, its data derives from ralative application systems.How to keep the data synchronization with that in the ralated application systems is an important question when constructing an Ecard system.This paper analyses the collecting mode of the Ecard data,puts forward an Ecard data synchronization solution by the data center based on SOA,and describes the process of data synchroization.The rusult proves the efficiency of the solution.

Key words: serviceoriented architechture;data center;data synchronization
