Due to the fact that script-driven apps gather their info in a database, adding more information to this sort of site shall not cause a bigger size of the application files, but in a bigger size of the database the website uses. In case you run a WordPress blog, for instance, the disk space that its database uses shall expand as you add new posts and website visitors leave comments underneath them. An expanding database could become an issue if the hosting account you use has limited space and sometimes even plans with unlimited space in general still have limited database space. Once you reach the limit, you shall not be able to add new content. Other possible results are that your website may not perform the way it ought to or that it might not appear online at all, which can result in lost customers.
