He quickly recognized SAP Web development as an emerging market and was instrumental in building Atos Origin's SAP Web development capability. He has successfully implemented all SAP Web technologies for the last 10 years for numerous customers. Since 2005 he has concentrated on Web Dynpro implementations, with a long track record in building successful component-based applications. This track record was the basis for his well-received SAP TechEd 2007 presentation on behalf of SDN. You may reach him at richard.tucker@atosorigin.com. Reusable components enable developers to build applications that are easy to understand, support, and maintain. This is the first installment in a three-article series that explores Web Dynpro componentization. This first article explains design methodologies and concepts underlying componentization and provides recommendations fundamental to a successful implementation. It also presents a real-world case study that used componentization to implement a suite of applications that delivered a lower TCO and a quicker ROI for the customer. This article deals with Web Dynpro for Java business applications implemented in SAP NetWeaver Development Infrastructure, but applies to Web Dynpro for ABAP as well.
