- Learn the ACID properties that guarantee reliable transactions.
- Use transaction control commands to manage database changes effectively.
Introduction
In MySQL, a transaction is a sequence of one or more SQL operations treated as a single unit. This ensures that either all operations succeed or none do, maintaining data integrity.
Transactions are critical in applications where multiple related changes must be applied together, such as banking or order processing systems.
