Abstract With the development of computer technology and the advancement of informatisation process，the data in various departments
are increasing at an unprecedented speed，different types of DBMS are managing the system storage and the data. Distributed heterogeneous
system leads to much inconvenience in data access among the enterprises，departments and organizations，thus greatly impairs the efficiency of
information utilisation. In light of this issue，this thesis presents a solution to realise data sharing in combination with the technologies of
metadata and Web Service. It gives full play to the advantages of metadata in data management and of Web Service in distributed handling，
realises the centralised management and distributed storage of the sharing data. A detailed research on the development and construction of
Chongming Island Ecological Environment Data Sharing Platform is conducted as well.
