Each attribute in a mongoDB document is seperated by commas. Each documents in the same collection can have different fields and attributes and each documents represents a single entity. MongoDB uses BJSON like documents for data storage and interchange . BJSON supports various datatypes such as string , numbers , arrays , nested documents , regular expression and more.
