Quiz on failure classification and storage, recovery and atomicity. A database management system (DBMS) failure can be classified into three categories: Transaction failure: When a transaction cannot be executed or continues to fail Disk failure: When hardware errors affect the disk drive System failure: When an active transaction is terminated Other types of failures include: Logical error, Network failure, Natural disasters, Carelessness, Sabotage, and Software errors. Each type of failure requires different management. For example, system crashes are often caused by software bugs,... Show more Quiz on failure classification and storage, recovery and atomicity.

Other types of failures include: Logical error, Network failure, Natural disasters, Carelessness, Sabotage, and Software errors.
Each type of failure requires different management. For example, system crashes are often caused by software bugs, but can also be caused by hardware errors.

Atomicity is a property of database transactions that ensures that a set of database operations either all occur, or none occur. This is important because it allows database transactions to be isolated from one another, ensuring that they are atomic, or indivisible.
