Learn MongoDB for Free

MongoDB is an open-source database that is document-oriented, and it is designed to store data on a large scale. It allows the user to work with stored data very efficiently. It is categorized under NoSQL, Not only SQL, database since the storage and retrieval of data in the MongoDB are not given in the form of tables. It provides driver support for popular languages like C, C++, C#, .Net, Go, Java, Node.js, Perl, PHP, Python, Motor, Ruby, Scala, Swift, Mongoid officially. This gives users an advantage to create an application using any of the supported languages. Many organizations like Facebook, Nokia, eBay, Adobe, Google, and many others use MongoDB these days to store large amounts of data. 

MongoDB is a database server and the data is stored in databases, this means, the environment gives its users a server that one can start and create multiple databases on it using MongoDB. Since it is a NoSQL database, the data is stored in collections and documents. Hence the database, collections, and documents are related to each other. The database contains collections like MySQL database has tables. Users can create multiple databases and multiple collections. There are documents inside the collections. The documents have the data that is to be stored in the MongoDB database. A single collection can contain multiple documents. It is schema less, that is, it is not necessary that one document has to be similar to another. The documents are created using the fields. Fields are key value pairs in the document like columns in the relational database. Value of the field can be of any BSON data types like double, Boolean, string, etc.

Storing nested data is allowed in MongoDB documents. Nesting of data allows the user to create complex relations between data. The data is stored in the same document which makes working and fetching of data extremely efficient compared to SQL. The maximum size of a BSON document is 16MB, whereas, in SQL, complex joins have to be written to fetch data from different tables. The data stored in MongoDB is formatted in BSON documents. BSON is the binary representation of JSON documents, which means, in the back end, the MongoDB server converts the JSON data into a binary form that is known as BSON. This BSON is stored and queried more efficiently.
