Q. What types of distributions are available for MongoDB?
A. General distributions for MongoDB support Windows, Linux, Mac OS X, and Solaris. Enterprise subscriptions also are available for professional and commercial applications that require enterprise-level capabilities, uptime, and support. If the MongoDB data is critical to your application and you have a high amount of DB traffic, you might want to consider the paid subscription route. For information on the subscription, go to https://www.mongodb.com/products/mongodb-subscriptions.
Q. Does MongoDB have a schema?
A. Sort of. MongoDB implements dynamic schemas, enabling you to create collections without having to define the structure of the documents. This means you can store documents that do not have identical fields.
