PHP web-based applications
mySQL is very popular with Web developers due to its excellent sql server database qualities, its speed, small size – and of course, the fact that it’s free. mySQL applications are machine independent, meaning they will work on a Microsoft Server as well as a Unix Server.
More mySQL advantages include:
- It's fast. Speed was the main goal of the people who developed mySQL
- It's inexpensive. mySQL is free under the open source license, and the fee for a commercial license is very reasonable.
- It's secure. mySQL's flexible authorization system allows some or all database privileges to specific users or groups of users. Passwords are encrypted.
- Supports large databases. 50 million rows or more! That is the number mySQL can handle at any given time. The default file size limit for a table is 4GB, but you can increase this if your operating system can handle it to a theoretical limit of 8 terabytes (TB).
Companies that use mySQL include Yahoo, Wikipedia, Craigslist, The Weather Channel, NASA, Evite, Ticketmaster, Citysearch, Alcatel, Pricegrabber, Neopets and more.
