MySQL is a relational database management system (RDBMS) based on Structured Query Language (SQL). Databases run the back-end of almost every website, business, corporation, school, etc; MySQL is a database management system that allows you to manage relational databases. It is open source software backed by Oracle.

• MySQL is very fast, reliable, and easy to use
• MySQL uses standard SQL
• It is free of cost
• MySQL works on many platforms and with many languages including PHP, PERL, C, C++, JAVA, etc.
• MySQL works well even with large data sets.
• MySQL supports large databases, up to 50 million rows or more in a table.

Keypoints to use MYSQL:-

• Database: A database is a collection of data stored in form of tables using various rows and columns.
• Redundancy: it means duplication of data. Storing data twice to make the system faster.
• Primary Key: A primary key is unique key, which does not contain null value.
• Foreign Key: A foreign key is the linking key between two tables.
• Compound Key: A compound key (composite key) is a key that consists of multiple columns, because one column is not sufficiently unique.
• Index: An index in a database resembles an index at the back of a book.
• Referential Integrity: Referential Integrity makes sure that a foreign key value always points to an existing row.

1)The first step is to download the Mysql server and choose the platform for which we want to download the server for example windows ,Linux or for Unix etc;

o MySQL Connectors (you’ll probably want to install them all because you never know              which future tool might depend on a particular connector)
