VbzCart/docs/tables/cache log

About

• Purpose: Log of all cache updates performed
• Notes:
  • The stored procedures don't automatically update this log; that is handled by the DataMgr classes.
• History:
  • 2009-03-24 Belatedly realized that it makes no sense to log source and destination each time; running the procedure updates a preset destination (a given function always updates the same destination) from all the function's sources.
    • Also added VbzUser, SysUser, and Machine, while I'm here (to be consistent with Template:Vbzcart/table). Sure, some updates are automatic, but some aren't.
