VbzCart/docs/tables/ord msg

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?
