ACID: A- Atomicity: Transaction should be complete or not complete. Transactions are taken as atomic unit. C- Consistency: The database must remain in a consistent state after any transaction I- Integrity: In a database system where more than one transaction are being executed simultaneously and in parallel, the property of isolation states that all the transactions will be carried out and executed as if it is the only transaction in the system. No transaction will affect the existence of any other transaction. D- Durability: The database should be durable enough to hold all its latest updates even if the system fails or restarts.

In Simple words, Normalization is to avoid the discrepancies or duplicates and maintain the data to retrieve easily. Mostly if you meet 2 or 3 Normal Forms then its enough for Database. Not required to satisfy all NF's. It may decrease the performance of DB if we try to satisfy all NF's and its not possible also. Now-e-days even doing De-Normalization in DB for some cases to achieve performance.
