Hi,

If I have table A with a PK_A primary key and the same with a table B and PK_B.

I have a relation table between A and B which called R_AB.

R_AB

---

PK_A
PK_B

If I write that PK_A and PK_B are ForeignKey from tables A and B, does the R_AB table takes any disk space more ?

The index are already defined in the table A and B.

Why ?
