Difference between Oracle and MongoDB

1. Oracle :
Oracle is a relational database management system (RDBMS). It was developed by Oracle Corporation in 1980. It is the first database designed for grid computing that provides the most flexible and cost-effective way to manage information and application. It runs on major platforms like Windows, Unix, Linux, and macOS. It is a relational database in which data is accessed by user through application or query language called SQL.

2. MongoDB :
MongoDB is a cross-platform document-oriented and a non relational (i.e., NoSQL) database program. It is an open-source document database, that stores the data in the form of key-value pairs. MongoDB was developed by MongoDB Inc. and initially released on 11 February 2009. It is written in C++, Go, JavaScript, Python languages. MongoDB offers high speed, high availability, and high scalability. Once MongoDB is installed, users can make use of Mongo shell as well. Mongo shell provides a JavaScript interface through which the users can interact and carry out CRUD operations.
