A model of information sharing based on isolated information system

In order to solve the problem of information resource sharing caused by information isolated island, this paper proposes a cross system online information resource sharing platform model based on the existing information system of colleges and universities, which is role and transaction oriented. The online resource sharing platform based on this model establishes a specific structure of intermediate database on the basis of the existing isolated information system, adopts the strategy of non authoritative data accurate association matching authoritative data, realizes its interconnection with the existing system databases through specific program algorithm logic, constructs a distributed interconnected database, and realizes cross database data association matching. After solving the problem of information island fundamentally, an information resource sharing platform that can define any role or transaction can be built to meet the current cross system information resource sharing needs. Based on the existing system management information, the purpose of accurately sharing information across systems by roles or transactions through the new platform is realized. Through the implementation and practical application of the model technology, it is proved that it can better solve the problem of information resource sharing caused by information island, and realize the accurate cross system information resource sharing service.
