Data Dissemination Diagram

Data Dissemination Diagram. Description Main Description The purpose of the Data Dissemination diagram is to show the relationship between data entity business service and application components The diagram shows how the logical entities are to be physically realized by application components This allows effective sizing to be carried out and the IT footprint to be refined.

1 Basic Concepts2 Developing Architecture Views in The Adm3 Views Tools and Languages4 Architecture Views and Architecture Viewpoints5 Conclusions6 Architectural Artifacts by Adm PhaseArchitectural artifacts are created in order to describe a system solution or state of the enterprise The concepts discussedin this section have been adapted from more formal definitions contained in ISO/IEC/IEEE 420102011 and ISO/IEC/IEEE 152882015They are illustrated in Figure 311 The “environment” of a system is the context determining the setting and circumstances of all influences upon a system Theenvironment of a system includes developmental technological business operational organizational political economic legalregulatory ecological and social influences A “system” is a combination of interacting elements organized to achieve one or more stated purposes The “architecture” of a system is the fundamental concepts or properties of a system in its environment embodied in itselements relationships and in the principles of its design and evolution An “Architecture Description” is a work product used to express an architecture a collection of architecture 3121 General Guidelines The choice of which particular architecture views to develop is one of the key decisions that the architect has tomake The architect has a responsibility for ensuring the completeness (fitnessforpurpose) of the architecture interms of adequately addressing all the pertinent concerns of its stakeholders and the integrity of the architecture in terms ofconnecting all the various views to each other satisfactorily reconciling the conflicting concerns of different stakeholders andshowing 3122 Architecture View Creation Process As mentioned above the TOGAF framework encourages but does not mandate the use of ISO/IEC/IEEE 420102011 Thefollowing description therefore covers both the situation where ISO/IEC/IEEE 420102011 has been adopted and where it has not ISO/IEC/IEEE 420102011 itself does not require any specific process for developing architecture viewpoints orcreating views from them Where ISO/IEC/IEEE 420102011 has been adopted and become wellestablished practice within anorganization it will often be The need for architecture views and the process of developing them following the ADM are explained above Thissection describes the relationships between architecture views the tools used to develop and analyze them and a standard languageenabling interoperability between the tools 3141 Example of Architecture Views and Architecture Viewpoints To illustrate the concepts of architecture views and architecture viewpoints consider the example of a very simpleairport system with two different stakeholders the pilot and the air traffic controller One architecture view can be developed from the architecture viewpoint of the pilot which addresses the pilot&#39sconcerns Equally another architecture view can be developed from the architecture viewpoint of the air traffic controllerNeither architecture view completely describes the syste 3142 Architecture Views and Architecture Viewpoints in Enterprise Architecture Now let us map this example to the Enterprise Architecture Consider two stakeholders in a new small computingsystem the users and the developers The users of the system have an architecture viewpoint that reflects their concerns when interacting with thesystem and the developers of the system have a different architecture viewpoint Architecture views that are developed to addresseither of the two architecture viewpoints are unlikely to exhaustively describe the whole system because each 3143 Need for a Common Language and Interoperable Tools for Architecture Description Tools exist for both users and developers Tools such as online help are there specifically for users and attemptto use the language of the user Many different tools exist for different types of developers but they suffer from the lack of acommon language that is required to bring the system together It is difficult if not impossible in the current state of thetools market to have one tool interoperate with another tool Issues relating to the evaluation of tools for architecture work a This section attempts to deal with views in a structured manner but this is by no means a complete treatise onviews In general the TOGAF framework embraces the concepts and definitions presented in ISO/IEC/IEEE 420102011specifically the concepts that help guide the development of an architecture view and make the architecture view actionable Theseconcepts can be summarized as 1 Selecting a key stakeholder 2 Understanding their concerns and generalizing/documenting those concerns 3 Understanding how to model and deal with those concerns The content metamodel is used as a technique to structure architectural information in an ordered way so that itcan be processed to meet the stakeholder needs The majority of architecture stakeholders do not actually need to know what thearchitecture metamodel is and are only concerned with specific issues such as “what functionality does this application support?””which processes will be impacted by this project?” etc In order to meet the needs of these stakeholders the TOGAF concepts ofbuilding blocks catalogs matrices and diagrams are used Building blocks are entities of a particular type within the metamodel (for example a business service called”Purchase Order”) Building blocks carry metadata according to the metamodel which supports query and analysis For examplebusiness services have a metadata attribute for owner which allows a stakeholder to query all business services owned by aparticular organization Building blocks may also include dependent or contained.
