The ZLE Framework
For a simple example of how a real-time solution can improve business operations,
consider what happens when a customer orders a product over the Internet. In the
traditional way of linking operational systems, the order application would reach into
the credit card system to check the customer’s credit card balance. This could result in
latency problems because:
•
Interacting with one another in this manner increases the burden on the business
systems.
•
If the credit card system were offline for some reason, there would be a further
delay in filling the customer’s order.
In a real-time environment, the customer’s credit card balance could be cached in the
central database at the center of the system, where it would be readily available to any
application that required it.
The ZLE Framework
Now let’s take a closer look at the individual components of a ZLE framework.
Figure 1-3 shows the basic ZLE framework architecture.
