How do I ensure data consistency and integrity in database transactions for my web application?
To ensure data consistency and integrity in database transactions for a web application, follow these steps:
1. Use a reliable database management system (DBMS) that supports ACID properties.
2. Implement proper transaction management by starting and ending transactions appropriately.
3. Use locking mechanisms, such as row-level or table-level locks, to prevent concurrent access to data.
4. Validate data before performing any updates or inserts.
5. Implement data validation constraints at the database level.
6. Use prepared statements or parameterized queries to prevent SQL injection attacks.
7. Monitor and log database transactions for auditing and troubleshooting purposes.
