MySQL databases
The Mysql database is a piece of software which has countless uses – there is a great deal of flexibility written into the design of the Mysql software, which has helped it go on from its humble origins to become one of the most widely used database packages in the world. If you have spent any good amount of time on the world wide web you have probably accessed a page on a web site which was based on data fetched from a Mysql database – in many cases even the people who write the content on a site are unaware of the technical aspects, and the fact that the things that they contribute are not actually written into HTML files on the site but are actually loaded into a Mysql database from which they are collected and presented to users with some kind of special script (usually using a server side scripting language such as PHP).
All kinds of data can be collected in a Mysql database – for example, on many web sites which use content management systems for multiple users with different levels of access, a Mysql database is used as the backend to hold the information about the content authors; Mysql is also used to hold the articles themselves, and this makes it easy for the content management system to present the information differently when the user wants to change the appearance of the site. A new style will be loaded through the content management system and it will be used to create a new set of PHP pages using server side scripting to give a new look to the site – all without making any changes to the content of the articles!
Mysql is also used in any kind of situation where a company wants to keep track of people – for example, a company will keep a database of all of the employees who work for it using the Mysql database software and some kind of front end will then be used to go through the information, make changes and send any kind of formatted files that are needed to the different sections of the company. Businesses will also use Mysql databases in the software which they use to keep track of their customers – when you make a purchase from a business on the world wide web it will usually store any information which you give it about yourself using a Mysql database, which makes it easy for them to compile lists of who is interested in different kinds of products and send out mailings to inform you about things which match your interest on their site.
Because Mysql is a flexible and reliable database program, it is used for these and many other kinds of applications all of the time on the world wide web. Learning the basics of how to interact with a Mysql database and how to code an interface for one gives you the ability to collect, organize and present information to users on the internet with the greatest of ease!
