VbzCart/docs/tables/cust

About

• Purpose: Core customer table – all the other customer data tables point to this one
• Fields:
  • ID_Repl: If non-null, then this customer ID has been consolidated with the customer whose ID is in ID_Repl; whenever/wherever possible, replace occurrences of this ID with the value of the corresponding ID_Repl.
  • WhenCreated: This should be NOT NULL on systems with no legacy data
  • WhenChanged: not sure if this field has a purpose; it could be set whenever Notes or ID_Repl are edited, maybe?
  • WhenUpdated: When this customer was updated (any time new order comes in, even if no contact info changes)
• History:
  • 2009-07-09 moved to separate wiki page; no design changes
  • 2011-11-29 added WhenUpdated field
  • 2013-10-10 added ID_User field (see Template:Vbzcart for rules)
