Getting Started with Mongo DB

What’s MongoDB?

MongoDB represents an open-source, document-oriented, developed and supported by a company called 10gen. MongoDB is written in C++, and it is a popular NOSQL database. NoSQL merely intends non-relational databases, i.e., there are table-like relational database structures. This formatting of stores is titled BSON and is many lookalikes to JSON.

Why is MongoDB used?

SQL was invented in the 70s for storing data. MongoDB stores documents (or) objects. Nowadays, everyone works with objects. For example, Python, Ruby, Java, etc., require databases for our objects to survive. Embedded documents and arrays reduce the need for joints.

Data as documents

  • MongoDB stores data in binary representation called BSON. The BSON encoding extends the popular JSON representation to include additional types such as int, long, date, floating-point, etc.
    All the data for a record given in the MongoDB documents will be contained in a single document.

When did MongoDB come into existence?
