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.

How can I ensure data integrity and security in my web application?

Ensuring data integrity and security in your web application is crucial to protect sensitive information and maintain your users’ trust. Here are some key steps:   1. Implement robust authentication and access control measures: Implement a strong user authentication system, such as two-factor authentication, to prevent unauthorized access. Use role-based access control to ensure that users only have access to the data they need. 2. Encrypt sensitive data: Use encryption algorithms such as AES or RSA to encrypt sensitive data, both during transit and at rest. 3. Regularly update and patch software: Ensure that all software components used in your web application (including frameworks, libraries, and the underlying operating system) are up to date and have the latest security patches installed. Vulnerabilities in outdated software can be exploited by attackers. 4. Conduct security audits: Regularly perform security audits and vulnerability assessments to identify and address any potential security flaws in your application. 5. Use secure coding practices: Follow secure coding practices, such as input validation
