ABSTRACT:
XML compression is a step towards using less resources e.g. to store or to transfer XML files, but it includes several challenges to apply standard database technology like query processing and updates efficiently to compressed XML databases. The challenges include for XML to compress better than e.g. gzip or bzip2 that generate non-queryable compressed data formats, to perform query processing on compressed XML faster than on uncompressed XML, and to perform updates in compressed XML data without decompression. Besides an overview of XML compression techniques, this talk shows the key ideas of how to meet theses challenges in compressed XML databases. Finally, the talk looks at how new research topics can be found by transferring research to a new domain.
