Aggregating user data
This technique applies to the Web presentation server, the Web application server, and the network. The goal is to allow rapid access to large customer data controlled by existing system applications and support personalization based on customer specific data.
Accessing existing customer data spread across existing system applications may cause these applications to become overloaded, especially when the access is frequent. This can degrade response time. To alleviate this problem, the technique calls for aggregating customer data into a customer information service (CIS). A CIS that is kept current can provide rapid access to the customer data for a very large number of customers; thus, it can provide the required scalability.
An issue with a CIS is that it needs to scale very well to support large data as well as to field requests from a large number of appservers (requesters).
