Intersystems Caché custom storage of persistent object

Try making the num, name, type, or pay property required (if there are any that cannot be null). Caché defines the ^kza("mltab","TAB","Dta",1) node because if the other 4 field are all null, the existence of the ^kza("mltab","TAB","Dta",1) node defines the existence of the row.
