Break
Break is a very powerful mapping format for numeric, date and time database fields. When you first map a numeric field always use Break or the related Partition.
The field is mapped into a series of nodes, each of which corresponds to a range defined by a series of break values, which are entered using the mapping option dialog.
Consider a date field being mapped using Break - Date with break values of 31-Dec-92 and 31-Dec-93. This would give nodes of :-
Similar techniques apply to Break - Numeric and Break - Time.
