Figure B-12 My computer folder 610 IBM WebSphere Application Server - Express V5.0.2 Developer Handbook
C Appendix C. Online Catalog application Throughout this publication we use the Online Catalog sample to illustrate the various features of WebSphere Application Server - Express. The application is a simple one that provides a means of publishing an inventory of goods on the Web and allowing customers to place orders via e-mail or by phone. This is by no means a replacement for WebSphere Commerce applications, but simply a way for small businesses to make their products known to potential customers. The application will provide a simple interface for non-programmers to enter information. Certain items can be identified as feature items. Customers can browse the information and e-mail the company for information. The application will be generic enough to apply to a variety of businesses. For example: ► A business that sells RVs can publish a current inventory of the campers on its lot. ► A restaurant can publish a takeout menu and provide a call-in number or fax number. ► A cleaning service can provide a list of services and prices. © Copyright IBM Corp. 2003 611
