If you use a script-driven platform for your Internet site, it stores its data in a database and the more substantial the website gets, the more info it stores. As an example, if you start an e-store, the size of the database that the e-commerce script employs shall increase whenever you add more items. Exactly the same applies for a forum script - the more users which register and the more comments they post, the bigger the database. If your sites become more popular or you simply want to include more content, this may be a problem in the event that your Internet hosting account has limited database space for storage. What the exact effect of hitting the limit will be depends on the script - the site can function properly, but you may not be able to add any new information; the website can be displayed with errors; or, in the worst case scenario, the entire internet site could simply go offline.
