Data Base
The important terms are:
Query specifications. The language elements (statements, clauses, commands, ...) that
you specify to provide ENFORM with the information it needs to retrieve data and to
establish the query environment.
Query. One complete LIST or FIND statement. Both statements specify the information
to be retrieved.
Target-list. A part of the query; a target-list consists of target-items and a special type of
target-item called a by-item.
Target-items. Any record names, field names, variable names, aggregate names, literals,
or expressions, excluding by-items, whose values you want to appear as output from
your query.
