Abstract:

Data sharing is the core content of information resources management. The traditional pointtopoint way of data sharing features the defects: to increase the time necessary to establish new applications in the application system to an already existing link between the applications, to meet many troubles in different application system upgrades or interface changes, to remodify the connection between different applications at least, which do not lead to its flexibility. This paper presents a data sharing mode based on information supermarket. The mode makes the new information resources dynamically join without modifying the interfaces between systems.
