Since script-driven applications gather their content inside a database, adding more content to this type of site shall not cause a larger size of the application files, but in a larger size of the database your website employs. If you run a WordPress blog, for example, the disk space its database employs shall grow as you add new posts and visitors leave responses below them. A growing database may become a problem if the website hosting account you use has limited storage space and occasionally even plans with unlimited space in general have limited database space. Once you reach the limit, you shall not be able to add new info. Other possible outcomes are that your internet site may not work the way it ought to or that it may not appear online at all, which can result in lost potential clients.
