Which integration method involves using shared databases?

The correct answer highlights a significant approach to integration known as database-centric integration. This method fundamentally relies on utilizing shared databases as the core component for system communication and data exchange. In database-centric integration, different applications or systems connect to a common database to read from and write to, which ensures that all systems share a consistent view of data.

Using a shared database allows multiple applications to operate on the same dataset simultaneously, enhancing data availability and consistency. This integration style is particularly beneficial in contexts where high data integrity is crucial, as it avoids the challenges of data duplication or discrepancies that can arise in other integration methods.

In contrast, API-centric integration focuses on utilizing application programming interfaces (APIs) for communication between various software systems. This method is more about real-time data access and functionalities rather than relying on a shared data repository.

Message-oriented middleware is designed to facilitate communication between distributed systems through message passing, which does not involve a shared database but relies on a messaging queue or broker.

File transfer methods involve moving data files between systems, which can create delays and challenges in maintaining real-time data consistency, unlike the more streamlined process found in database-centric integration.

By concentrating on shared databases, database-centric integration effectively streamlines data management and fosters a cohesive environment for diverse
