Explanation:-

MongoDB is a document database used to build highly available and scalable internet applications. With its flexible schema approach, it's popular with development teams using agile methodologies. In comparison to the SQL server, MongoDB is faster and more scalable. While the SQL server supports JOIN and Global transactions, MongoDB does not. The MS SQL server does not accommodate large amounts of data, however MongoDB does. MongoDB is a non-relational document database that provides support for JSON-like storage. The MongoDB database has a flexible data model that enables you to store unstructured data, and it provides full indexing support, and replication with rich and intuitive APIs . SQL databases are used to store structured data while NoSQL databases like MongoDB are used to save unstructured data. MongoDB is used to save unstructured data in JSON format. MongoDB does not support advanced analytics and joins like SQL databases support  MongoDB uses the MongoDB Query Language (MQL), designed for easy use by developers. The documentation compares MQL and SQL syntax for common database operations. Traditional SQL databases continue to have a place in application development and storage. It's unlikely MongoDB will completely replace MySQL, but it's possible that both structured and unstructured databases will be used for different purposes in one environment.
