  1. This paper stresses on discussing the architecture, access protocol and implementation mechanism based on xml and web services technologies, researches key technologies of metadata information service and data uniform access and management in database grid, designs and implements distributed mis subsystem and das subsystem, which support multi - domain management. mis can provides metadata information for the whole system, such as das and clients, it uses domain name 、 logical name and internal name of data object to uniformly name database resources in grid and implements name mapping mechanism and user view metadata information service and provides virtual organization and management of database resources. das can provide a scalable uniform data access by virtual organization and management of storage resources and multi - mode data share access mechanism, thus integrate database resources in grid and shields distribution and heterogeneity of resources and achieves transparent access. system adopts data access mechanism based on user request mapping to flexibly implement data access across multi domains, and adopts distributed data cache mechanism 、 security mechanism based gsi to provide high - performance secure data service for grid users
