2MySQL is a relational database management system (RDBMS) from the
3Oracle Corporation. Like other relational systems, MySQL stores data
4in tables and uses structured query language (SQL) for database
5access. When MySQL developers need to access data in an application,
6they merge data from multiple tables together in a process called a
7join. In MySQL, you predefine your database schema and set up rules
8to govern the relationships between fields in your tables.

10MongoDB is a NoSQL database that stores data as JSON-like documents.
11Documents store related information together and use the MongoDB
12query language (MQL) for access. Fields can vary from document to
13document - there is no need to declare the structure of documents to
14the system, as documents are self-describing. Optionally, schema
15validation can be used to enforce data governance controls over each
16collection.
