Relationships using comparative operators
In a comparative relationship, you use one or more of the following operators
to compare match field values in the two related tables. The relationship returns
related records when the comparison evaluates successfully, according to the
criteria you establish.
In this example, the Tour Date fields in the Tours table and the Clients table are
match fields. If a record in the Tours table has a Tour Date value of 12/11/2010,
all the records in the Clients table with a Tour Date value of 12/10/2010 or
earlier are related to it. In the Clients table, if a record has a Tour Date value of
12/11/2010, all records in the Tours table with Tour Date values of 12/12/2010
or later are related to it.

= Values in match fields are equal

< Values in the left match field are less than values in the right match field
≤ Values in the left match field are less than or equal to values in the right match

> Values in the left match field are greater than values in the right match field
≥ Values in the left match field are greater than or equal to values in the right match

x All records in the left table are matched to all records in the right table, regardless
of the values in the match fields
