In case you work with a database-driven script app for your site, all of the content that you or the website users add, will be kept in cells and tables within a database, not as ordinary text in the application files. In comparison, HTML sites are static and all of the content on such a site is a part of the actual HTML files. A web-based store application, for instance, takes all prices, items, user reviews, and many others, from its database and this is valid for any other script that enables you to make a dynamic site. The more the content you insert, the larger the database gets, so if you use a script-driven website, you should make sure that your hosting package comes with adequate database storage space. The latter applies no matter what type of databases you will use - for example MySQL or PostgreSQL.
