Adatabaseis a collection of information that is organized so that it can easily be accessed, managed, and updated. There are many databases commonly, relational and non relational databases. Relational databases usually work with structured data and non relational databases are work with semi structured data. In this paper, the performance evaluation of MySQL and MongoDB is performed where MySQL is an example of relational database and MongoDB is an example of non relational databases. A relational database (the concept) is a data structure that allows you to link information from different 'tables', or different types of data buckets. A non-relational database just stores data without explicit and structured mechanisms to link data from different buckets to one another.
