A proper ending for a long but shallow chapter from Node.js in Action book:
Don’t be afraid to use more than one type of storage mechanism in an application. If you were building a content management system, for example, you might store web application configuration options using SQLite, stories using MongoDB, and user-contributed story ranking data using Redis. How you handle persistence is limited only by your imagination.
I still need to see some solid Node.js applications, as so far except visualizing Wikipedia, Node.js + NoSQL Database => Real Time Chat Applications.
