Why do we not have to save changes to database files, in the same way that we do with word processing, spreadsheet & other kinds of files?

When accessing a database through an application, the application handles the save for the user. So for instance, when you click "submit" on your question, the submit is performing the database insert and therefore saving your data for you. If the person is inserting data into the database directly via SQL, then the user needs to perform a commit, which will then save the data.

Databases write information directly to disk as it is entered, so there is no need to save, except for design changes.
