  31                         <p>There are many ways to get your data into DataTables, and if you are working with seriously large databases, you might want to consider using the server-side options that DataTables provides. Basically all of the paging, filtering, sorting etc that DataTables does can be handed off to a server (or any other data source - Google Gears or Adobe Air for example!) and DataTables is just an events and display module.</p>
  32                         <p>The example here shows a very simple display of the CSS data (used in all my other examples), but in this instance coming from the server on each draw. Filtering, multi-column sorting etc all work as you would expect.</p>
