Application and user location diagram

The application and user location diagram shows the geographical distribution of applications. It can be used to show where applications are used by the end users; the distribution of where the host application is executed and/or delivered in client scenarios; the distribution of where applications are developed, tested, and released, and so on. Analysis can reveal opportunities for rationalization, as well as duplication and/or gaps. The purpose of this diagram is to clearly depict the

Application communication diagram

The purpose of the application communication diagram is to depict all models and mappings related to communication between applications in the metamodel entity. It shows application components and interfaces between components. Interfaces may be associated with data entities where appropriate. Applications may be associated with business services where appropriate. Communication should be logical and should only show intermediary technology where it is architecturally relevant.

Application migration diagram

The application migration diagram identifies application migration from baseline to target application components. It enables a more accurate estimation of migration costs by showing precisely which applications and interfaces need to be mapped between migration stages.

The aim is to define the trajectory between the current version of the IS and the version that you wish to obtain, over several stages. The component deployment technique enables you to present the same component deployed in

Enterprise manageability diagram

The enterprise manageability diagram shows how one or more applications interact with application and technology components that support operational management of a solution. This diagram is really a filter on the application communication diagram, specifically for enterprise management class software. Analysis can reveal duplication and gaps, and opportunities in the IT service management operation of an organization. It would identify temporary applications, staging areas, and the

Process/System realization diagram

The purpose of the process/system realization diagram is to clearly depict the sequence of events when multiple applications are involved in the execution of a business process. It enhances the application communication diagram by augmenting it with any sequencing constraints, and hand-off points between batch and real-time processing. It would identify complex sequences that could be simplified, and identify possible rationalization points in the architecture in order to provide more timely
