You are curently running MongoDB. More details on this database management system here.
SUDSJS has been developed to run with several different database systems. You can switch here, but this site is reset to CouchDB every morning.
Switching databases is not something you would do in production, because it changes the database for the whole system (or at least the whole thread). It is intended for demonstration and testing only. The databases in the test system are at various levels of development. The Couch database that loads up each morning is probably the most stable. I am in the process of testing each configuration so there may be issues.
If you do switch databases you won't notice much difference. The databases structure and content is very similar. But for NOSQL databases there will be some denormalised and structured data. For Couch DB there are a few views set up that illustrate how you can speed up processes.
