Database Conversion Based on Relationship Schema Mapping

As the Internet of Things Data Sharing Platform is going to exchange the data, the problem of heterogeneous data have to be solved, which means the problem of interconnection of kinds of database systems accessed to the platform should be solved, and it should also provide the services of data sharing and transparent data accessing between heterogeneous databases. In this paper, data conversion technology based on relationship schema mapping is proposed, which has achieved data conversion between relationship databases. Exchanging and conversion of heterogeneous data which is the problem Data Sharing Platform facing to has been analyzed, practical technology of exchanging XML heterogeneous data has been studied, the specific implementation mechanism has been developed, the problems like message losing, relationship misjudging and field attribute changing during data exchanging has been solved, and the XLM heterogeneous data exchanging method during relationship databases is general and integral has finally proved by experiment results.
