Given that script-driven apps collect their content inside a database, incorporating more information to this sort of Internet site will not cause a bigger size of the application files, but in a bigger size of the database your Internet site employs. In case you run a WordPress blog, for example, the disk space which its database employs shall grow anytime you add new posts and visitors leave comments beneath them. A growing database can become an issue if the website hosting account which you use has limited space for storage and sometimes even plans with unlimited space in general still have limited database storage area. Once you reach the limit, you won't be able to add new content. Other potential outcomes are that your website may not work the way it ought to or that it might not appear online at all, which may result in lost potential customers.
