Next you highlight or answer questions about the components properties. For instance, by dragging the XML Exporter into place it asks you to highlight what properties of a component to export and instantly generates and exports XML formatted code.

The next tool is an enhanced version of Simplicity for Mobile Devices. With this tool, you can create robust applications for any PDA, phone, or pager using the Java Technology-enabled MIDP (Mobile Information Device Profile) API. This special version of Simplicity for Mobile Devices integrates a midlet with the servlet. For communication purposes, it includes the Simplicity XML Transaction Caching Engine.

According to Data Representations, Inc., the XML Transaction Caching Engine eliminates the need to write a custom parser that accepts and sends XML data communication between a server and handset. It automates the transfer of data between the server and the mobile device.

First it parses XML data and maps it to the integrated MIDP application. Then it caches requests to the server in the handset if the server isn't available. It also caches XML responses from the server in the handset if the server isn't available. The Transaction Engine also features a licensing tool for the management of billing models for the benefit of carriers, developers, and Application Service Providers.

Conclusion
As Data Representations, Inc. says, "Just imagine testing the caching of a database operation on a phone or PDA when service isn't available. A developer can disconnect the server and view where and how the data is cached on the handset. Then re-connect to the server, re-enabling connectivity, and watch the server receive the response entries."
