Swift Lesson: Operational Database Management
Introduction
Operational Database Management refers to the processes and techniques used to manage operational databases, which are designed to handle real-time transactional data. These databases support the daily operations of organizations and are critical for business functionality.
Key Concepts
- **Transactional Operations**: These involve CRUD operations (Create, Read, Update, Delete) that manage data effectively.
- **Concurrency Control**: Ensures that multiple transactions can occur simultaneously without leading to data inconsistency.
- **Data Integrity**: Guarantees the accuracy and reliability of data over its lifecycle.
- **Backup and Recovery**: Essential for data protection, allowing the restoration of data in case of loss or corruption.

Best Practices
- **Regular Backups**: Schedule automated backups to prevent data loss.
- **Indexing**: Use indexing to optimize query performance.
- **Normalization**: Apply normalization techniques to reduce data redundancy.
- **Security Measures**: Implement proper authentication and authorization controls.
