In a complex system with multiple databases, describe a strategy for managing transactions to maintain data consistency across these databases using Entity Framework.

Option 4: Implementing a transactional messaging system provides a robust strategy for managing transactions across multiple databases in a complex system. This approach involves employing message queues or distributed messaging protocols to coordinate data updates between databases asynchronously. By decoupling the transactional process from the databases themselves, this method ensures eventual consistency across distributed systems, even in scenarios with high latency or network failures. It offers flexibility, scalability, and fault tolerance, making it suitable for complex environments where maintaining data consistency is paramount.
