abstract |
Various approaches have been discussed to efficiently represent
hierarchic data structures, such as XML documents, in main memory and
on persistent storage. Based on previous DBIS work in Konstanz, a
compressed, tuple based tree encoding was chosen to encode XML data,
limiting the storage of tree nodes to their unique node ids and their
parents ids. To demonstrate the efficiency of accessing and querying
the data structure, we present implementations of proven visualization
techniques, along with the option of filtering the shown data with the
XML language XPath. Further we introduce a visualization to analyze
query access patterns on block storage. In the scope of this workshop, we want to discuss the chosen data structure, visualizations and explore new areas for applying compressed tree encodings. |
