There are the trends that the users hope to retrieve information among lots of individual database systems distributed in lots of virtual organizations. To connect all these individual database systems into a virtual database system is a significant issue. This paper presents VIRGO_DDBMS, a framework of distributed database system based on virtual hierarchical tree Grid organizations(VIRGO) P2P network. The table space are classified as hierarchical domains like DNS. The servers hosting database systems joins several groups of VIRGO network according to the owned tables' domains. VIRGO_DDBMS is effective for data update and retrieve by using distributed SQL statements. We use the policies which cache the host machines' addresses of database systems to avoid the overload of traffic of root nodes in tree structure. The proposal presented here can construct a virtual distributed database system which can manages huge volumes of data by connecting all database systems together which are owned by the individual virtual organizations.
