VbzCart/tables/cust addr

About

• Fields:
  • ID_Cust is a new field for the migration; I had this wacky idea that customers might need to share addresses (one customer buys a present for a friend; friend sets up an account and then moves, first friend buys another present but doesn't get the updated address...) but this turned out to be kind of a stupid idea. Consequently, the [Contacts x Addrs] table in the Access version also went away.
  • Tag will at first be set only by us, but later on customers will be able to set it and will be increasingly in charge of it.
  • WhenVoid is when the record was voided -- distinct from WhenExp, which would be set for when a valid address record would no longer be appropriate (e.g. customer moving out on a set date)
  • Full: the complete address formatted for printing (e.g. on a label).
    • Given that postage-printing apps seem to require seperate fields, and handle the formatting themselves, this field may not be as useful as it was when labels were separate from postage.
  • Search: the complete address, with all punctuation (including spaces) stripped out - so that changes in punctuation, capitalization, spaces, etc. don't prevent a match from being found. This is recalculated automatically from edits to Name, Street, Town, State, Zip, Country.
  • Search_raw should probably be replaced by a hash at some point, because it's just a value to make it easier to detect when Search needs recalculation - it's currently (I think) just Name, Street, Town, State, Zip, and Country fields appended together (with linebreaks).
  • State probably needs to be separate fields for as-entered and code-if-known
• History:
  • 2009-07-09 Moved to separate wiki page; no design changes
  • 2011-11-22 Added WhenEnt and WhenUpd
  • 2012-01-03 Added WhenVoid
  • 2012-01-11 Tentative definitions for Full and Search; added ID_Country
  • 2013-11-26 Renamed Name to Label; added 255-char Name field for addressee name
  • 2014-08-30 Removed ID_Country for now -- not yet implemented in database, and we're not ready for it yet.

Discarded

Might use this in the future, but things get tricky. Do we get a complete list of countries from somewhere, or do we allow customers to enter new ones? In the latter case, NULL would need to be acceptable. <mysql>
