In the Belle II experiment, we have to design the database for the detector configuration (defined as ConfigDB, now) and for the calibration/alignment (defind as CalibDB).
The former is for, e.g. "run configuration", "software/farmware version" "dead/hot channels" and the latter for the detector constants (e.g. alignment, calibration, timing, pedestal, etc).
Today, we had a coordinator meeting to discuss the database issue.
And we concluded that we should have a database group, but not formed yet.
(I attached a slide shown in the coordinator meeting)
As a first step to design and establish the database (DB) scheme, we need to know the requirements to the DB from each sub-detector.
For instance, what kind of data has to be stored, how large it is, how frequently access to the DB, etc. Could you discuss this issue in you group and report to me your requirements.
I think that the current Belle database used in offline analysis will helps you to start the discussion in your group.
And please assign (a) responsible person(s) who can work on this issue.
I would like to set the deadline to the September 6th (Mon), 2010. 17:00PM (JST) sharp. I believe that each group has at least one meeting by that time.
