The Vcodex platform for data compression. (English) Zbl 1181.68150
Filipe, Joaquim (ed.) et al., Software and data technologies. Second international conference, ICSOFT/ENASE 2007, Barcelona, Spain, July 22–25, 2007. Revised selected papers. Berlin: Springer (ISBN 978-3-540-88654-9/pbk). Communications in Computer and Information Science 22, 201-212 (2008).
Summary: Vcodex is a software platform for constructing data compressors. It introduces the notion of data transforms as software components to encapsulate data transformation and compression techniques. The platform provides a variety of compression transforms ranging from general purpose compressors such as Huffman or Lempel-Ziv to structure related ones such as reordering fields and columns in relational data tables. Tranform composition enables construction of compressors either general purpose or customized to data semantics. The software and data architecture of Vcodex will be presented. Examples and experimental results will be given showing how the approach helps to achieve compression performance far beyond traditional approaches.
