We are pleased to announce the 13th Annual Tcl/Tk conference (Tcl'2006), sponsored by Noumena Corporation , Digital Smarties , Eolas Technologies and ActiveState . Efficient data manipulation and storage for Tcl with Vlerq and RatclAuthor: Jean-Claude WipplerAbstractVlerq and Ratcl are two new extensions for Tcl which provide a general data-query and data-manipulation foundation for dealing with in-memory and persistent data. A wide range of high-performance operators are available, including all the usual relational, set-wise, and vector-oriented primitives. Taking lessons from the Metakit embedded database library, these extensions use a column-wise "inverted" storage format to achieve excellent performance using very compact data representations. The design choices made to match Tcl optimally and some performance results will be presented, as well as a perspective on what the implications could be for Tcl application development.
