Transaction Management

Ensuring data consistency through proper transaction design.

Context

You are designing transactions. Use appropriate isolation level; understand lock behavior.

Domain Context

• ACID: Atomicity, Consistency, Isolation, Durability
• Isolation Levels: Read Uncommitted, Read Committed, Repeatable Read, Serializable
• Locks: Shared (read), exclusive (write); deadlock possible
• Deadlock: Two transactions waiting for each other; database detects and rolls back
• Consistency: Invariants maintained; foreign keys, constraints
