SQL V/S MYSQL?????? What is the PC requirement to install the both????

SQL It is the language used to query the database, select and find records, insert and delete. It's a standard that is poorly followed but the basics are supported by all. MySQL It is a database engine that accepts the SQL and follows the instructions it recieves passing out the relevant data as required. Get the latest version of SQL server from the internet. You don't need any special hardware to use and install it. You just need enough RAM (512 MB Recommended) and Hard Disk Space.

Mysql and Sql is different with each other. Mysql is use with PHP and apache for dynamic web development. SQL server is used for oracle programming.
