I found many refer url for Meteor framework where i found mongodb as database, since i don\'t have much knowledge in mongodb. So is there any way to implement mysql instead
From the documentation:
Today most Meteor apps use MongoDB as their database because it is the best supported, though support for other databases is coming in the future. The Meteor.Collection class is used to declare Mongo collections and to manipulate them. Thanks to minimongo, Meteor's client-side Mongo emulator, Meteor.Collection can be used from both client and server code.
As the client side uses minimongo, using a RDBMS may not provide the best fit (as the query language and data structures are very different).
You might be interested in something like breeze.js which comes at the problem of rich data synchronization services from a different direction, but it fits relational databases.
