Decision Support
In this figure, as the business grows, the ZLE system is expanded to include an
additional NonStop server and services.
A flexible ZLE system should allow a business to purchase only as much hardware as
it needs initially and to add components to the existing hardware to match the growth
of the applications. And it should not impose a performance penalty as you add
hardware increments. For example, adding twice as many processors should provide
twice as much performance for your applications. As you will see in later sections, the
scalability of the SQL/MX database and NonStop server makes these things possible.
Decision Support
A ZLE system must be able to support the decision support and data mining needs of a
business. The HP implementation of the data store can provide this support. A ZLE
data store contains current and integrated information that cannot be found in a
traditional corporate data warehouse. The data store can be queried directly using
industry-standard decision support and business intelligence tools.
Figure 2-5 on page 2-15 shows a typical decision support environment. In this
environment, information is extracted from databases and used to make strategic
company decisions. In a ZLE framework, the information can be routed back into the
ZLE core and used to enrich data in the data store or as it passes through the core to
other ZLE applications. It can be used to add models and rules generated by data
mining tools into the ZLE core. The figure shows the flow of information from the local
systems, through the ZLE hub to the data warehouse, and back to the hub.
