This is a very good point, and I think I have a hard time explaining how it works technically without it sounding more complicated than it actually is. What

The diagram is a good idea, I'll do it. For a simple explanation, what do you think about:

    SQLPage is a web server that runs .sql files to answer web requests. For every request, it runs the SQL statements in the requested file one by one, passing the HTTP request parameters as SQL statement parameters. Then, it passes the results returned by the database to pre-defined HTML components to create a good-looking webpage that is streamed back to the user's web browser.
