The Real-Time Enterprise
purchases with the company and has never experienced any credit problems.
However, in this case, as the clerk enters the customer’s credit card number into the
company’s credit card system, a message is returned indicating that the purchase is
$5.00 over the customer’s credit limit. The clerk, unaware of the customer’s history
with the company, must reject the customer’s credit card. Again, the result is an
unhappy customer who deserved much better treatment.
In a real-time environment, the credit card processing application would have access to
the customer’s previous transactions. Based on these transactions, software in the
real-time solution could return a recommendation to extend the customer’s credit limit.
Figure 1-1 and Figure 1-2 graphically illustrate how a real-time solution, based on a
zero latency enterprise framework, eliminates information latency in a business.
Figure 1-1 shows a conceptual example of a large business before the implementation
of a real-time solution. Notice that the business has many different operational
systems. Each operational system might have its own applications and databases and
may even be located at geographically distant locations, all communicating over a
network. The network might work reasonably well in ultimately getting information
where it is needed, but the problem is the latency, or delay, involved getting it there.
