JVO Query Language 2003/11/27 CVO Meeting in Beijing

SkyQL & ADQL JVOQL has been adopted as one of the basis for SkyQL (standard query language in IVOA) XML description of SkyQL = ADQL Astronomical Data Query Language 2003/11/27 CVO Meeting in Beijing

Serious Issue Q) GT2 has too large overhead before starting actual jobs !! They are several seconds. A) For batch jobs, such as database accesses, the overhead could be negligible. However users can never wait for several second for interactive data analyses. Request) Overheads must be < 0.1 seconds excluding the network delays. 2003/11/27 CVO Meeting in Beijing

Partially solved !! Introduction of NMI -- authentication module : binary Analysis of the source codes of GTK2 -- polling interval : 30 sec -> 3 sec Elapsed time was halved ! But …, still very slow. 2003/11/27 CVO Meeting in Beijing

Improvement of U.I. Need to know about SQL to use JVOQL → An editor to create JVOQL from GUI Edittable on screen →　more flexibility for advanced users 2003/11/27 CVO Meeting in Beijing
