Atomicity-Atomicity states that database modifications must follow an “all or

nothing” rule. Each transaction is said to be “atomic.” If one part of the transaction

fails, the entire transaction fails.

Aggregation - A feature of the entity relationship model that allows a relationship set

to participate in another relationship set. This is indicated on an ER diagram by

drawing a dashed box around the aggregation.
