Atomicity:-
Atomicity means a transaction should complete its all the operations or perform non of the operation. If the transaction fail in between execution then it rollback to its previous state without any changes.
Aggregation:-
Aggregation is a process in which relation between two entity is treated as a single entity.

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. It is critical that the database management system maintain the atomic nature of transactions in spite of any DBMS, operating system or hardware failure. On the other hand Data aggregation is a type of data and information mining process where data is searched, gathered and presented in a report-based, summarized format to achieve specific business objectives or processes and/or conduct human analysis.

Atomicity: It’s an all or none concept which enables the user to be assured of incomplete transactions to be taken care of. The actions involving incomplete transactions are left undone in DBMS.

Aggregation: The collected entities and their relationship are aggregated in this model.It is mainly used in expressing relationships within relationships.
