This is a very simple (yet practical) example of web application leveraging DeeBee as a persistent store.
The whole state of application is held in RAM. Cyclically and during application shutdown the state is persisted to disk using DeeBee store.
When application is starting, state is restored and loaded again into memory.
The state is also replicated once per hour to a second directory (which can be an NFS file system).
Please note that application is lacking in multiple areas: security, input validation, testing etc. I wanted to focus only on those topics related to storing application state.
