This all-new technical reference guide, the newest in the SAP PRESS Essentials Series, shows you how you can use RIAs - Rich Internet Applications (for reporting and analysis tasks, for example) - to reduce the load on your database and your application server.

Readers learn how to shift all layout information - and even parts of the application logic - from the SAP Web Application Server, to the client. You'll uncover the advantages of the RIA approach, learn how to solve layout issues, and implement client-side data retrieval through Web services. The author selected Flash MX 2004, an ideal tool for developing modern business applications, as the front-end technology, and shows you how to leverage its greatly improved graphical formatting options and comparatively simple development techniques, to make your project a success.
