About

  • Purpose: Record of messages sent/received about this order
  • Notes: This subsystem should probably be rethought at some point when everything else is working -- possibly should be part of the order event log, along with Template:Vbzcart
  • Relates to: Template:Vbzcart, Template:Vbzcart, Template:Vbzcart
  • History:
    • 2009-07-09 Adapted from MS Access
    • 2009-07-10 Changed "Notes" from VARCHAR(255) to MEDIUMTEXT
  • Fields:
    • TxtFrom (was "From")
    • TxtTo (was "To")
    • TxtRe (was "Subject")
    • doRelay: does message need to be sent to a third party? (this has a specific meaning, but if I can't remember/reconstruct what it was... are any records using it?)
    • WhenRelayed should only ever be set if doRelay is TRUE
    • Notes may contain the substance of the message record, because sometimes it's more about what happened than about a single message being transferred
  • Future:
    • Possibly message relaying should be handled by a separate app, but if not it needs to be rethought a bit:
      • Template:Vbzcart should probably include a flag to indicate if a given medium (method?) needs human relaying (NO = automatic, like email)
      • Is WhenRelayed basically the mirror of WhenCreated, just in the other direction? Or can they both have meaning in the same context?
