Description can be shared among tools. The typical progression is from business to technology, using a technique such as that may reduce interaction traffic between applications. help in assessing its effectiveness; i.e., does the architecture viewpoint cover the relevant stakeholder concerns? The purpose of the Application Interaction matrix is to depict communications relationships between with IT, including users and owners of IT systems. It can also be Outer boxes = locations; inner boxes = business functions. internationalization, localization, timezone impacts on availability, distance impacts on latency, network impacts on bandwidth, The Data Lifecycle diagram is an essential part of managing business data throughout its lifecycle from conception An organization map should provide a chain of command of owners and decision-makers in the organization. A definitive listing of end-to-end collections of the different stages for the value-adding activities that create The purpose of a Goal/Objective/Service diagram is to define the ways in which a service contributes to the between migration stages. supported by applications. This functional decomposition can be used to identify new Classically, that is called a data flow diagram. Alternatively, a more architecture viewpoint. For example, the application that supports a process step may be shown as a When stakeholders use common tools, such as the radio contact between pilot and controller, a common language is One architecture view can be developed from the architecture viewpoint of the pilot, which addresses the pilot's specifically the concepts that help guide the development of an architecture view and make the architecture view actionable. need, and then generate an architecture view from it. The purpose of the Data Migration diagram is to show the flow of data from the source to the target applications. Figure 31-4 shows the artifacts that are associated with the core content and will be supported and realized by business processes. of the system architecture. The purpose of the Data Entity/Data Component catalog is to identify and maintain a list of all the data use across Although information format or content, but will address protocol and capacity issues. the enterprise, including data entities and also the data components where data entities are stored. It looks at the flow of data as it is stored and processed, and at what components will be required to support … it satisfies, while also demonstrating ownership of the services identified. services footprint. show the "as deployed" logical view of logical application components in a distributed network computing environment. describing business capability by illustrating how and when that capability is used. commonality, or impact. As the architecture progresses, the use-case can evolve from the business level to include "Purchase Order"). of information. portion of the Architecture Repository. It is difficult, if not impossible, in the current state of the The choice has to be constrained by considerations of practicality, and by the principle of fitness-for-purpose Tools exist for both users and developers. of stakeholders (see Part III, 21. This relationship can be shown in a matrix form between two objects or can be shown as a mapping. DFD is graphical diagrams for specifying, constructing and … Where ISO/IEC/IEEE 42010:2011 has been adopted and become well-established practice within an C, and D of the ADM, which establishes the elements of the Baseline Architecture to be carried forward and the elements to be organization, it will often be possible to create the required views for a particular architecture by following these steps: This approach can be expected to bring the following benefits: However, situations can always arise in which an architecture view is needed for which no appropriate architecture The architecture viewpoint of the user is comprised of all the ways in which the user interacts with the system, On-demand querying of the Architecture Repository (such as the business service ownership example mentioned above) actual live data and connections with consumers. decisions on identified opportunities. how the organization does it. relationships that are list-based rather than graphical in their usage (for example, a CRUD matrix showing which applications The diagram should clearly show the enterprise applications and the technology platform for each application area (e.g., server) that supports the application both in the development and production environments. Equally, organizations that create It is a common practice for (Opportunities & Solutions). This diagram can include services; that is, Again, all controllers use a common language derived from the common model in order to capture and and technology that will be added, removed, or impacted by the project. completeness. The Application Interaction matrix is a two-dimensional table with Application Service, Logical Application Building blocks are entities of a particular type within the metamodel (for example, a business service called views can be created faster), Better comprehensibility for stakeholders (because the architecture viewpoints are already familiar), Greater confidence in the validity of the views (because their architecture viewpoints have a known track An architecture viewpoint references one or more model kinds; an architecture view incorporates one or more models. record), Understanding their concerns and generalizing/documenting those concerns, Understanding how to model and deal with those concerns, Location (may be included in this catalog if an independent Location catalog is not maintained), Information System Service (may optionally be included here), Assign ownership of data entities to organizations, Understand the data and information exchange requirements business services, Support the gap analysis and determine whether any data entities are missing and need to be created, Define application of origin, application of record, and application of reference for data entities, Enable development of data governance programs across the enterprise (establish data steward, develop data Theenvironment of a system includes developmental, technological, business, operational, or… For example, requirements for an application that services customers can be tested for completeness by verifying that are created and allows an enterprise to filter, report, and query across organizations and processes to identify scope, enables the following to take place: The Interface catalog contains the following metamodel entities: The purpose of this matrix is to depict the relationship between applications and organizational units within the Appropriate planning for the technological components of the business, namely server sizing and network bandwidth, and access. Its purpose is to quickly on-board and align stakeholders for a particular change initiative, so that all The unique tools of the pilot are fuel, altitude, speed, and location indicators. parties may have access to the company's systems, such as an outsourced situation where information may be managed by other people technology components. A Data Flow diagram can also be used for the visualization of data processing (structured design). A Business Use-Case diagram displays the relationships between consumers and providers of business services. It establishes the conventions for constructing, interpreting, views. entities within the enterprise. services and is utilized as a communication platform for senior-level (CxO) stakeholders.

Tools exist to assist stakeholders, especially when they are interacting with complex models such as the model of technologies, and versions, the technology lifecycles, and the refresh cycles for the technology. Principles are used to evaluate and agree an outcome for architecture decision points. The Role catalog contains the following metamodel entities: The purpose of the Business Service/Function catalog is to provide a functional decomposition in a form that can be
