Query Processing for High-Volume XML Message Brokering
نویسندگان
چکیده
XML filtering solutions developed to date have focused on the matching of documents to large numbers of queries but have not addressed the customization of output needed for emerging distributed information infrastructures. Support for such customization can significantly increase the complexity of the filtering process. In this paper, we show how to leverage an efficient, shared path matching engine to extract the specific XML elements needed to generate customized output in an XML Message Broker. We compare three different approaches that differ in the degree to which they exploit the shared path matching engine. We also present techniques to optimize the post-processing of the path matching engine output, and to enable the sharing of such processing across queries. We evaluate these techniques with a detailed performance study of our implementation.

An Effective Approach for Modifying Xml Documents in the Context of Message Brokering
XML message brokering systems support customization that modifies the structure and content of XML messages under dissemination. This allows customized content delivery and data and application integration. In this work we present an approach for modifying XML documents in the context of XML message brokering. In our approach we propose to store XML data in its native form in a BDB XML database...

As moving to big data world where data is increasing in unstructured way with high velocity, there is a need of data-store to store this bundle amount of data. Traditionally, relational databases are used which are now not compatible to handle this large amount of data, so it is needed to move on to non-relational data-stores. In the current study, we have proposed an extension of the Mongo...
