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.
