The clickstream system was deployed on three web sites, including a commercial high-volume web server environment. In the production environment, the basic reporting user interfaces and data population infrastructure was initially used. After a period of several months, the commercial web site decided to reduce the scope of the process for faster turnaround and used the clickstream logging and loading facilities only. A single developer was able to write simple code to replace the standard population code to fit their needs. Thus, two conclusions can be drawn from this case study. First, the componentized nature of the system allowed it to be easily adapted to fit the specialized needs of the client. Second, the version of data population code and hardware that the client site used was inadequate to handle the load of the web site.
