Anything that can be represented by a unique URL that you could type in a web browser will count towards your Google Mini's document limit. This includes the file types that are indexed by the Google Mini, such as Microsoft Word documents, Microsoft Excel spreadsheets, PDF files, and HTML files. Since they're all under a single URL, multi-page documents would count as only a single document. Many sites employ dynamic content based on a single dynamic file (an index.php file, for example). These sites often employ variables in the URL to distinguish different pages, articles, and products using a single page (index.php?product_id=1234, for example). Each one of these unique page URLs counts as a separate document. How this relates if you have a database system is dependent on the design of your database powered site (or the specific web enabled database system in use). Most often, one URL will display one row of results, obtained from a query against one or more tables -- but many other organizations are possible, depending on the requirements of your specific application.
