Sirix is a versioned, treebased storage system. It provides
an ID-less diff-algorithm to import differences between two versions (currently XML-documents). Furthermore
an ID-based diff-algorithm facilitates the comparison of versions stored within
Sirix. A GUI with several visualizations for comparing these versions visually is
available to aid an analyst. Versions are stored using well known versioning strategies (full, incremental, differential).
The architecture is especially well suited for flash-disks because of a COW-principle. In the future we aim to provide throughout security as
well as a replaced page-structure to speedup our architecture. A brackit(.org) binding will
enable XQuery and the XQuery Update Facility. Temporal XPath axis and possibly diff-functions will help analysts to gain quick knowledge from the stored data.
