Need for Transaction Processing

A.C.I.D

• Atomicity
• - Either all committed or all rolled back
• Consistency
• - Follows user defined integrity constraints
• Isolation
• - A transaction is invisible to other users until completed
• Durability
• - Once committed the results are permanent and survive future system and crashes

• Finding your data fast
• - Data should be accessible fast enough to cater to the huge number of request every second
