Technology Component Architectures are used to capture the high-level, logical technology architecture that describes the classes of technology that should be used. This tutorial introduces the Technology Component Architecture and describes how they are defined in Essential Architecture Manager.
Technology Composites are a special kind of Technology Component that are used to capture components that make up the logical technology component architecture of a solution. That is, the set of types of technology (not products, yet!) that form the technology architecture of an application, e.g.:
Create a new Technology Composite following the steps described for how to Define Technology Component. The name of the composite should reflect the architecture it models. This may be specific to a particular application or solution (e.g. 'MyApp Technology Architecture') but ideally will be a more general and re-usable thing (e.g. 'Standard J2EE Application Technology Architecture'), that you can use to manage your technology strategy.
To complete the task of creating the Technology Component Architecture definition:
