Techniques Used in Database Administration

Full Answer Section

      Transaction Management To effectively manage database transactions during peak business hours, the following strategies will be implemented:

• Isolation Level: The SNAPSHOT isolation level will be employed to optimize concurrency and performance while maintaining data integrity.

This level provides a consistent snapshot of data for each transaction, minimizing blocking and deadlocks.  

• Error Handling: Robust error handling mechanisms, including TRY-CATCH blocks and rollback procedures, will be implemented to prevent data inconsistencies in case of errors.
• Batch Processing: Non-critical tasks like report generation will be scheduled for off-peak hours to reduce database load and improve transaction performance.
• Transaction Logging: The database system will be configured to utilize transaction logging to maintain data integrity and enable point-in-time recovery.

Database Security A comprehensive security framework will be established to protect sensitive data and prevent unauthorized access:

• Access Control: Implement role-based access control (RBAC) to grant permissions based on job functions. Strong password policies, including complexity requirements and regular password changes, will be enforced.
• User Authentication: Utilize multi-factor authentication (MFA) for critical system access to enhance security.
• Data Encryption: Employ encryption techniques to protect sensitive data both at rest and in transit.
• Network Security: Implement firewalls, intrusion detection and prevention systems (IDPS), and network segmentation to protect the database infrastructure.

 

• Regular Security Audits: Conduct periodic vulnerability assessments and penetration testing to identify and address security weaknesses.
• Security Awareness Training: Educate employees about security best practices and the importance of protecting sensitive information.

Backup and Recovery A robust backup and recovery plan is essential to minimize data loss and ensure business continuity. The following strategies will be implemented:  

• Full Database Backups: Regular full database backups will be performed to a secure off-site location.
• Transaction Log Backups: Frequent transaction log backups will be implemented to enable point-in-time recovery.
• Backup Rotation: A backup rotation schedule will be established to optimize storage utilization and retention requirements.
• Disaster Recovery Plan: Develop a comprehensive disaster recovery plan outlining procedures for restoring database operations in case of a catastrophic failure.
• Test Restores: Regular test restores will be conducted to verify the integrity of backups and the effectiveness of the recovery process.

  Analysis This database administration plan aligns with the organization's goals by protecting critical data, minimizing downtime, and ensuring business continuity. By implementing robust transaction management, security measures, and a comprehensive backup and recovery strategy, the plan addresses the key challenges identified in the case study. The use of SNAPSHOT isolation level, strong access controls, and encryption will enhance data integrity and confidentiality. Regular backups and testing will ensure rapid recovery from system failures. By combining these elements, the plan provides a solid foundation for managing the database system and mitigating risks.
