When you start a website, you have a lot of things to consider. First of all, you will of course want to choose the proper website hosting company to support you as you begin to build your site; these companies exist solely to support websites and to make the creation process, as well as maintaining your creation, as easy as possible. Once you have picked your website hosting company, you can set about securing your own domain name, and from there can begin to create your website. At this point, you have what amounts to full creative sway over all aspects of your site that fall within your hosting company’s capabilities, and, generally, the complicated and technical sides of things will be of no concern to you. However, for some people, it can be interesting to learn a bit about the underlying foundations of your website, such as systems like MySQL.
MySQL, which is a sort of abbreviation for the casual term “My Sequel” is what is called a “relational database management system” that may be a part of the operating system of your website. In fact, MySQL is used in a number of the Internet’s most popular and most frequently visited websites, such as Google and Facebook, among others. As noted on the MySQL Wikipedia page (incidentally, the Wikipedia website uses MySQL as well), MySQL exists as a server that allows multiple users access to a number of databases. There are different levels or versions of MySQL available, but, for those interested, it is worth knowing that at least a basic version of the MySQL server may be in use when you create a personal website through a popular hosting company.
This is just one of a number of comprehensive computer programs, coding languages, complex servers, etc. that may be a part of the functionality of your website. Ultimately, it is not necessarily required of you (depending on how your domain host works) to understand this side of things, or to be able to make any sense of it. However, for those with more computer experience, or those who simply have an interest in how things work, and not simply what they result in, these sorts of things can be quite interesting. There is, after all, much to learn about the computer science behind all of the creations you conceive of and the changes you implement while designing your own website. In the end, an increased understanding of this computer science will likely help you to be able to understand how to make a better website as well.
