In this chapter, you return to the Book Seller, Inc. case study used in Chapter 9. First, quickly review some of the main issues facing this company. ReviewBook Seller, Inc. is having problems handling the high customer volume, and requests are timing out during the afternoon peak hours. The shopping cart needs to be expanded to support customer needs, but the technology is no longer supported. Book Seller, Inc.'s affiliates need to have real-time stock and pricing information on products through XML Web Services. Security must be tight because a year ago, a Trojan worm penetrated Internet Information Services (IIS) and corrupted the database. The inventory management system and the storefront system need to share data. The inventory system runs a DB2 database, and the storefront system runs a SQL 6.5 database with an ASP 3.0 user interface. The storefront system uses very few business objects; the database server is accessed directly through the user interface (UI). The storefront infostructure includes three servers in a Web farm and one database server. |
