 <td valign="top" class="text">In this section, we'll show you how to use FusionCharts and PHP to plot charts from data contained in a database. We'll create a pie chart to show &quot;Production by Factory&quot; using: 
 <ul>
 <li>dataXML method first.</li>
 <li>Thereafter, we'll convert this chart to use dataURL method. </li>
 </ul>
 We've used MySQL database here. The database dump is present in Download Package &gt; Code &gt; PHP &gt; DB folder. You can, however, use any database with FusionCharts including MS SQL, Oracle, Access etc. 
 Before you go further with this page, we recommend you to please see the previous section &quot;Basic Examples&quot; as we start off from concepts explained in that page. 
 The code examples contained in this page are present in Download Package &gt; Code &gt; PHP &gt; DBExample folder. The MySQL database dump is present in Download Package &gt; Code &gt; PHP &gt; DB. </td>

 <td valign="top" class="text">The database contains just 2 tables:
 <ol>
 <li>Factory_Master: To store the name and id of each factory (Columns : FactoryID &amp; FactoryName ) . </li>
 <li>Factory_Output: To store the number of units produced by each factory for a given date.(Columns : FacrotyId, DatePro, Quantity) .</li>
 </ol>
 For demonstration, we've fed some dummy data in the database. Let's now shift our attention to the PHP page that will interact with the database, fetch data and then render a chart. </td>
