dc.description.abstract Query processing of inte grated XML databases has increasingly gain attention in the last few years. It helps users to extract information fr om an integrated XML databases system. The big challenge of query processing of integrated XML databases is to find a suitable model for query processing, metadata representation and da ta instance integra tion. Such a model will increase the flexibility of query processing pr ocesses as well as serve users with friendly integrated data. The proposed framework displays any successes. Through a single request, without concern about their internal structures and geographical distribution, it allows decomposition of global queries into sub-queries conformed simultaneous ly to local format. In order to reduce the redundancies of mappings, low-level metadata pr ocessing has been introduced; it yields two direction-mapping for query decomposition and data conversion from the original metadata. It is also shown how to extract data to provi de user-friendly resu lts. XML Declarative Description is applied to all components of the framework as their underlying model.
