When a relationship is applied to a linear asset, we add a new record to the history table with a created date.  When the attribute is modified, we add a removed date to that record and create a new record with a new created date.  This allows us easily access relationship history.
Ko je za linearno sredstvo uveljavljeno razmerje, dodamo v tabelo zgodovine nov zapis z datumom ustvarjenja.  Ko je atribut spremenjen, temu zapisu dodamo datum odstranitve in ustvarimo nov zapis z novim datumom ustvarjenja.  To nam omogoča enostaven dostop do zgodovine razmerij.
