Question : access 2007 relationships

i'm using access 2007, and during my work i observed that a new table created in the page of the relationships named as one table named but in addition (_1) as the original table named business type and the auto-created table called business type_1.
it is not a real table it just found in the relationships page.
please tell me if it is an error or something.

Answer : access 2007 relationships

Aggreed. In Access, you can add a table multiple times into the relationships.  This is done for the following example:

TblA has relationships with tblB and tblC. TblB and TblC dont have relationships with one another.

Mainly this is done for ease of use, to avoid creating a relationship between the 2 unreleated tables accidentally.

If it is not causing any problems, it is safe to ignore.
