A link is a popular way to describe relationships in a relational database.
There are three types of relationships (links) between tables:
1. One-to-one <span>relationship , that allows only one record on each side of the relationship.
2. </span>One-to-many <span>relationship, that allows a single record in one table to be related to multiple records in another table.

that out.
If you bought it with full knowledge that you intend to
"borrow" and return it, yes. If you only need something for a short
time, look for someone you can borrow or rent one from. Yes, that might
be a little more effort, and it might actually cost something, but it's
the right thing to do. With that practice, the store is losing money on
the "open box" item, and essentially, every other customer there is now
paying for whatever you were doing. And because of you, people with
valid reasons to return something have to fight over "restocking fees"
and the like.</span>
