= Description = [http://xarch.sourceforge.net/ XArch] is an archive management system that allows one to create, populate, and query archives of multiple database versions. It is based on a nested merge approach that efficiently stores multiple database versions in a compact archive. The system allows one to create new archives, to merge new versions of data into existing archives, and execute both snapshot and temporal queries using a declarative query language. XArch is an output from DCC-funded research at [http://www.ed.ac.uk/schools-departments/informatics/ Informatics at the University of Edinburgh]. Any questions or comments regarding XArch, please contact [http://homepages.inf.ed.ac.uk/hmueller/ Heiko Mรผller]. = User Experiences = = Development Activity =
