Summary
You have seen that the client/server mode in db4o is quite simple. Everything is done via configuration in the code. The networking mode allows connections, with authentication, from remote clients, whereas the embedded mode works for concurrent access by multiple clients within the same virtual machine. Finally, you have learned how a client can communicate with the server “out of band.”
In the real world a lot of companies use these kinds of client/server communication features. For example, MR Controls, based in Calgary, uses this db4o feature extensively. They build SCADA (Supervisory Control and Data Acquisition) systems for power utilities and the gas and oil industry.
In the next chapter you will learn about database transactions in db4o, and in particular about how they work in the case of concurrent clients.
