 
The generic function 
update-record-from-slot
 updates an individual data item in the column represented by 
slot
. The 
database
 is only used if 
instance
 is not yet associated with any database, in which case a record is created in 
database
. Only 
slot
 is initialized in this case; other columns in the underlying database receive default values. The argument 
slot
 is the CLOS slot name; the corresponding column names are derived from the View Class definition.
