Differences between RDBMS and MongoDB

RDBMSRDBMS stands for Relational Database Management System. It stores data in entity form as tables. It provides multiple layers of information security. Each table may or may not have a primary key (used to uniquely identify records in the table) and foreign keys (used to identify the relationship between the two tables). RDBMS uses SQL language to query the database. Examples of popular RDBMS are oracle, sqlserver, mysql, etc. MongoDBMongoDB is a NoSQL database. It's open source. It is a document-oriented database that uses BSON (the binary version of JSON). BSON is a document storage format. MongoDB stores data in the form of documents and does not use SQL to query
