What methods ensure database stability when operating on a single server in case of failures?

Several methods are used to ensure the stability of a database on a single server:

• Regularly creating backups for data recovery in case of failures.
• Using transaction logs (write-ahead logging) for rollback or recovery after failures.
• Setting up monitoring and alerts for quick response to issues.
• Applying replication or clustering mechanisms, if possible, to increase fault tolerance.

For example, in a Java application, you can configure automatic database backups using a scheduler and use transactions to maintain data integrity.
