How TrueCredit Utilizes SOA to Build Fast, Reliable Applications
1. What are the major reasons the company (TrueCredit) had to use SOA?
TrueCredit used Service-Oriented Architecture (SOA) because the changes needed to be implemented quickly(90 days the norm is 180 days). SOA reuses and reconnects existing IT components instead of building a new system. One application is to support 50,000 users simultaneously, which is double the previous capacity. Another objective was to reduce response time from 3 seconds to 1 second.
2. In what ways did they gain competitive advantage by using SOA?
TrueCredit now has the ability to quickly and easily collect and analyze data from several sources. Services such as credit reporting, scoring, and other financial services are offered on both TrueCredit's website and its customers website, giving more exposure to TrueCredit's goods and services.
3. What specific "services" can you identify in a business like this?
TrueCredit is a subsidiary of a national U.S. credit bureau. Companies like this offer credit reports, computes credit scores, and other financial and credit services.
4. Why is it so important to serve 50,000 simultaneous users?
TrueCredit wants the capability to service all customers at the same time without slowing down the system. It currently has the capacity to service 25,000 simultaneously. An objective of any company is to attract new customers and increase business, so in other words, TrueCredit needs room to grow. While it is very unlikely that all customers would use TrueCredit's services at the same time, it needs to have the capability to handle such a situation.
5. Classify this application using the material in Section 2.2.
This application is primarily an interorganizational system because it connects TrueCredit to its customers by storing, analyzing and quickly retrieving financial data when it is requested. Because this application is used to offer services and programs on its customer's websites as well as its own, it could also be classified as a transaction processing system.

Given the current credit crisis in America, what credit standard does it use to draw its conclusions? It's own or the companies which rely on it?
Reading it seems this may be one of the companies that approves in store credit applications and the like.
I would also be curious to see their eventual credit default rates.
