Evaluating XML queries over compressed data The XQueC Query Processor consists of a query parser, which is standard, an optimizer and evaluator. ...
The XQueC system adheres to the following approach: (I) XQueC takes advantage of the XMill principle of compressing separately data and structure for efficiently querying compressed data. ...

More recently, some compressors have been proposed to query compressed XML data. ...
Although many effective XML compressors, such as XMill, have been recently proposed to solve this data inflation problem, they do not address the problem of running queries on compressed XML data. ...
Thirdly, XQzip utilizes the index to query the compressed XML data. ...

Some XML compressors do not support querying compressed data, while other XML compressors which support querying compressed data blindly encode tags and data values using predefined encoding methods. ...
To overcome the verbosity problem, the research on compressors for XML data has been conducted. ...
Therefore, the reconstruction is needed for XQueC to transmit the compressed XML data through the network. ...

We study the applicability of XML path summaries in the context of current-day XML databases. ...
We find that summaries provide an excellent basis for optimizing data access methods, which furthermore mixes very well with path-partitioned stores. ...

We propose to use an XML compression technique that compresses an XML document to a binary directed acyclic graph (DAG) and to use DAG-based DOM evaluation on the client side. ...
Whenever Ajax applications on mobile devices have to retrieve large XML data fragments from a remote server, a reduction of the exchanged data volume may be crucial to manage limited bandwidth and limited ...
According to [5] , the DAG also allows a more efficient search and query evaluation as could be provided on the original XML data, even for large repositories of data. ...
