As discussed in Chapter 1, different perspectives are required to have a holistic view of the enterprise IT infrastructure. These perspectives are known as composite targets and are created by relating individual target models. These include different models such as groups and system targets as well as service targets. Groups and system targets provide the mapping between the business goals and the underlying IT infrastructure. The service targets help in visualizing and monitoring the availability, performance, and service-levels of various business functions provided within an enterprise. While group targets are homogeneous collections of targets that are logically related, system targets are heterogeneous in nature. OEM 11g provides support for all these modeling paradigms. As is evident, such composite modeling paradigms are applicable only in a wider context within an enterprise. These models are not meant to be applied at an individual target level.
