| Abstract | Query processing of integrated XML databases has increasingly gain attention in the last few years. It helps users to extract information from 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 data instance integration. Such a model will increase the flexibility of query processing processes 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 simultaneously to local format. In order to reduce the redundancies of mappings, low-level metadata processing 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 provide user-friendly results. XML Declarative Description is applied to all components of the framework as their underlying model. |
