Realtime and databases — a discussion on coupling versus modularity

Databases and event-driven architectures are essential for organizing information efficiently. Realtime databases combine storage and realtime features, but they may struggle with scaling and modularity. To achieve high cohesion and loose coupling in large applications, it is crucial to decouple realtime concerns from storage concerns. Developers should evaluate their requirements and choose the right tools for each job, such as a dedicated database solution and a scalable realtime component. Modularity ensures that systems can be scaled independently, providing better performance and user experience at scale.
