Web Services are also an option.<br />I would highly recommend you attend some Appian training (<a href="http://www.appian.com/business-process-management/bpm-training/bpm-training-overview.jsp)">www.appian.com/.../bpm-training-overview.jsp)</a> to learn some basics of Appian application design.<div style="clear:both;"></div>
