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: when the contact's dependent records (address, emails, etc.) were last modified (probably not implemented much)
    • WhenUpdated: When this record was last modified
  • History:
    • 2009-07-09 moved to separate wiki page; no design changes
    • 2011-11-29 added WhenUpdated field
    • 2013-10-10 added ID_User and Title fields (see core_users for rules)
    • 2016-06-12 switching definitions of WhenChanged and WhenUpdated
      • Only one record had WhenUpdated set; very few have WhenChanged set.
    • 2019-07-02
      • renamed from "core_custs" to "cust" so it will group with the other customer tables
      • removed NOT NULL constraint on ID_Name because we need to create this record before we create the cust_names record
        • perhaps we can make this unnecessary later with transactions? but it messes with debugging, even so, so maybe we should just put in a post-creation test to make sure all necessary fields got filled in (log data error if not)
