采用元数据Web Service技术结合的数据共享研究

ON DATA SHARING WITH COMBINED TECHNOLOGIES OF METADATA AND WEB SERVICE

随着计算机技术的发展和信息化进程的推进,各部门的数据以令人惊异的速度增长,不同数据库管理系统存储并管理着数据,异地系统间的异构性使企业和机构间的数据访问存在诸多的不便,大大降低了信息的利用效率。针对这一情况,提出了结合元数据和Web Service技术实现数据共享问题的解决方案,充分发挥元数据在数据管理方面的特性和Web Service在分布式计算上的优势,实现共享数据的集中性管理和分布式存储,并对崇明岛生态环境数据共享平台的开发建设进行了具体的研究。

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.
