%X In this paper, the concept of global distributed data sources over WWW(WWWDS) is introduced. A simple and extensible data model based on node, node container, node graph and link points are discussed in details. A powerful SQL like query language (WWWQL) for WWWDS is introduced and the query processing and optimization technology for WWWQL are discussed as well.
