questions on MongoDB!

couple of questions for you Treehouse members!

  1. what is Mongo Daemon really?
  2. How does MongoDB works really? My understanding is that there is a small version of the whole database temporarily running within your browser as the application rolls..... but when is it actually sent to Mongo and definitely stored?
  3. is there another way to look at your mongoDB other than using the shell?!

  1. mongod is "the primary daemon process for the MongoDB system. It handles data requests, manages data access, and performs background management operations.". Just think of it like a database server waiting for requests for data from 'clients' (one of which could be the mongo shell).
  2. That pattern of having a 'small version of the whole database temporarily running within your browser' is probably referring to Meteor's implementation of MongoDB, which runs both on the server and on the client so users see changes to the database immediately on the client-side, while they are still being run on the server. Meteor is an excellent JavaScript framework. I hope Treehouse makes a course about it at one point!
  3. Yes, there are tons of ways to access data from a MongoDB database, each of these is called a 'client'. There are client libraries available for most programming languages, and there are also standalone client applications, like Robomongo, that offer different takes on a more 'native' and user-friendly interface.
