The DB server node provides the database support for the Web
application. The data in the database is considered secure, as it is
protected by both the protocol firewall and the domain firewall.
Figure 1. Run time topology for user to online buying Pattern for e business
The pattern for e business also includes product selection. However, there is
currently no Linux option in the product selection; so, we have to define the
product selection ourselves. We implement the IBM HTTP server and IBM
WebSphere Application Server in the commerce server node; whereas on the
DB server node, we put IBM DB2 and the Lotus Domino Enterprise Server.
For simplicity, we do not implement the firewall or the dispatcher.
For in depth discussion on user to business and user to online buying
patterns and their guidelines, refer to the
Patterns for e business:

Edition
