togaf data architecture artifacts

Centraal in de methode staat de Architecture … As a piece of software grows in size, so the complexity and inter-dependencies between different parts of the code increase. A "view" is a representation of a whole system from the perspective of a related set of concerns. We discuss it briefly here because of areas of overlap. The purpose of the Product Lifecycle diagram is to assist in understanding the lifecycles of key entities within the enterprise. solutions. Edgar Codd, then at IBM, developed the relational model in 1973. It is useful in systems upgrade or application consolidation projects. multiple applications are involved in executing a business process. The references to “components, relationships and structure” in both the IEEE and TOGAF definitions are quite formal in their context rather than casual. following to take place: The Data Entity/Business Function matrix shows the following entities and relationships: The purpose of the Application/Data matrix is to depict the relationship between applications (i.e., application Diagrams can also be used as a technique for graphically populating architecture content or for checking the The RM-ODP Reference Model defines a set of distribution transparencies that are applicable to the TOGAF Software Engineering view. presentation layer, a business logic or application layer, and a back-end data store layer. Most OODBMSs incorporate a general-purpose programming language. The notation used is from the Unified Modeling Language (UML) specification. How is data change propagated in a distributed environment? The purpose of this catalog is to identify and maintain a list of all the applications in the enterprise. entity. show the "as deployed" logical view of logical application components in a distributed network computing environment. The purpose of the Data Security diagram is to depict which actor (person, organization, or system) can access which enterprise data. If implemented correctly, there would be no need for application code to "know" about the implementation details of the data. The content fra… The local components relate to assets that are located relatively close together geographically. An architecture viewpoint references one or more model kinds; an architecture view incorporates one or more models. In most cases, regional and metropolitan networks are used to connect local networks. The Project Context diagram links a work package to the organizations, functions, services, processes, applications, data, and technology that will be added, removed, or impacted by the project. The choice of which particular architecture views to develop is one of the key decisions that the architect has to Avancier’s TOGAF quick reference charts ... artefacts Phase C Data Architecture artefacts Phase C Application Architecture artefacts Phase D Technology Architecture artefacts Organization/Actor Catalog Role Catalog Business Service/Function Catalog Driver/Goal/Objective Catalog They building blocks, catalogs, matrices, and diagrams are used. controller sees the system. called an architecture viewpoint, such as an air flight versus an air space model. it is not the intent of the Organization Decomposition diagram to link goal to organization, it should be possible to intuitively Architecture) as listed in 11.4 Outputs . An architecture view will comprise selected parts of one or more models, chosen so as to In general, TOGAF embraces the concepts and definitions presented in ISO/IEC 42010:2007, specifically the concepts that help guide the development of a view and make the view actionable. The data access tier provides a standardized view of certain classes of data, and as such functions as a server to one or more application logic tiers. It is important to note that technology processing can influence and have It has been popular, in terms of commercial use, since the early 1980s. The This means that the required data is available Anytime, Anywhere, by Anyone, who is Authorized, in Any way. In the model, clients are processes that request services, and servers are processes that provide services. Data protection is necessary to prevent unauthorized users from understanding the content of the database. The security context is therefore analogous to a common operating system notion of user process space. Business functions are performed by organizational units. Deliverables; Artifacts; Building Blocks; Artifacts. until disposal within the constraints of the business process. least implicitly, and that defining the architecture viewpoint in a systematic way (as recommended by ISO/IEC/IEEE 42010:2011) will For example, a project to upgrade desktop A "system" is a collection of components organized to accomplish a specific function or set of functions. The Application and User Location diagram shows the geographical distribution of applications. This implies use of commercial common carriers and private common-user communications systems as the CN provider between LSEs. In the current state of the market, different tools normally have to be used to develop and analyze different views throughout the process. It focuses on how the system is implemented from the perspective of security, and how security affects the system properties. The Enterprise Manageability diagram shows how one or more applications interact with application and technology The Data Lifecycle diagram is an essential part of managing business data throughout its lifecycle from conception (HIPAA, Sarbanes-Oxley, etc). Forms of information include data, imagery, voice, and video. perspective. In this course, you will learn about the areas of TOGAF that relate to Content Metamodels, Views, and building an Enterprise Architecture practice. To achieve maximum flexibility, software should utilize a five-tier scheme for software which extends the three-tier paradigm (see Figure 35-6). developed, visualized, communicated, and managed using a tool. business functions within the enterprise. This focus for security protection is based on the open system, distributed computing approach for information systems. Applications will create, read, update, and delete specific data entities that are associated with them. The mapping of the application interactions shows in matrix form the equivalent of the Interface Catalog or an Application Communication diagram. This interconnection is likely because open systems may consist of an unknown number of heterogeneous LSEs. This commercial software is like a backplane onto which capabilities can be plugged. Figure 1. Its purpose is to quickly on-board and align stakeholders for a particular change initiative, so that all This diagram can be elaborated or enhanced as detailed as necessary. kind of interface, whether via a batch file that is loaded periodically, a direct connection to another application's database, or The Network and Communications diagram will take logical connections between client and server components and architecture views is an iterative process. Each change in state is represented on the diagram which may include the event or rules that trigger that change in state. Many different tools exist for different types of developers, but they suffer from the lack of a In particular, the security management function controls information needed by operating system services within the end system security architecture. It is difficult, if not impossible, in the current state of the tools market to have one tool interoperate with another tool. Building blocks may also include dependent or contained entities as appropriate to the context of the If roles are defined, understood, and aligned across organizations and applications, this allows for a more seamless user experience and generally more secure applications, as administrators do not need to resort to workarounds in order to enable users to carry out their jobs. information. airport system with two different stakeholders: the pilot and the air traffic controller. The users of the system have an architecture viewpoint that reflects their concerns when interacting with the Application services are consumed by actors or other application services and the Application Use-Case diagram provides added richness in describing application functionality by illustrating how and when that functionality is used. C, and D of the ADM, which establishes the elements of the Baseline Architecture to be carried forward and the elements to be The TOGAF document set is designed for use with frames. as listed in 6.4 Outputs . added, removed, or replaced. It is typically the start point of the Application Architecture phase. The Data Entity/Data Component catalog contains the following metamodel entities: The purpose of the Data Entity/Business Function matrix is to depict the relationship between data entities and business functions within the enterprise. In terms of distribution, the master/slave model is one step up from the host-based model. It shows application components and interfaces between components. turn allow stakeholders to be identified and related change initiatives to be aligned or consolidated. The mapping of the Application Component-Application Component entity relationship is an important step as it An "architecture description" is a collection of artifacts that document an architecture. The ORB specifies how objects can transparently make requests and receive responses. exchange to achieve a specific purpose. Now let us map this example to the Enterprise Architecture. The client typically initiates communications with the server. The diagram is useful for the following reasons: The scope of the diagram can be appropriately defined to cover a specific application, business function, or the entire enterprise. Business functions are performed by organizational units. The purpose of the Process Flow diagram is to depict all models and mappings related to the process metamodel entity. stakeholders. common language that is required to bring the system together. The Business Service/Information diagram shows the information needed to support one or more business services. The organization of the components within a tier is flexible and can reflect a number of different architectures based on need. This view should be developed for personnel involved in the acquisition of any components of the subject architecture. How is backup managed while running continuously? As the architecture progresses, the use-case can evolve from the business level to include data, application, and technology details. The Business Service/Information diagram shows an initial representation of the information present within the architecture and therefore forms a basis for elaboration and refinement within Phase C (Data Architecture). TOGAF® 9 Template Artifacts and Deliverables, Set 2 Reference: I093. It is highly desirable that an architecture description be encoded in a standard language, to enable a standard approach to the description of architecture semantics and their re-use among different tools. operating systems will need to identify all locations where desktop operating systems are deployed. or simply could be an informal "eye-chart" providing an overview of the technical environment. Viewpoints are generic, and can be stored in libraries for re-use. ... Data Architecture: Data Entity-Business Function Matrix, System-Data Matrix; The purpose of the Application/Function matrix is to depict the relationship between applications and business Information is multiple tokens of data combined to convey a message. It is important to note that the The artifacts identified in 35.6 Architectural Artifacts by ADM Phase can be used to address specific concerns of the stakeholders, and in some instances the artifacts can be used with the view of the same name; for example, the Software Engineering diagram, Communications Engineering diagram, and Enterprise Manageability diagram. The Communications Engineering diagram will take logical connections between client and server components and identify network boundaries and network infrastructure required to physically implement those connections. the other axis. There must be some kind of physical connectivity between the systems. Process Flow diagrams show sequential flow of control between activities and may utilize swim-lane techniques to business services have a metadata attribute for owner, which allows a stakeholder to query all business services owned by a achievement of a business vision or strategy. This diagram is developed to address the concerns of: The purpose of the Data Dissemination diagram is to show the relationship between data entity, business service, The Business Service/Function catalog contains the following metamodel entities: The Location catalog provides a listing of all locations where an enterprise carries out business operations or houses architecturally relevant assets, such as data centers or end-user computing equipment. Information domains are not necessarily bounded by information systems or even networks of systems. Additionally Access Control Lists (ACLs) and security schema definitions are used to model and implement security. Moreover, each of these progressions has to be made for two distinct environments: the existing environment (referred to as the baseline in the ADM) and the target environment. logic, and data store layers and service-level requirements of the components. With an enterprise architecture tool using the TOGAF 9.1 artifacts The TOGAF 9.1 core metamodel provides a minimum set of architectural content to support traceability across artifacts. As mentioned above, at the present time TOGAF encourages but does not mandate the use of ISO/IEC 42010:2007. This chapter discusses the concepts surrounding architecture artifacts and then describes the artifacts that are recommended to be created for each phase within the Architecture Development Method (ADM). The mapping of the Application Component-Organization Unit relationship is In this step the procurer looks at the viability of the concept. A Project Context diagram shows the scope of a work package to be implemented as a part of a broader transformation Description can be shared among tools. It enhances the Application Communication diagram by augmenting it with any sequencing constraints, and hand-off The Business Service/Information diagram shows the information needed to support one or more business services. This diagram should also show the existence and location of different deployment environments, including Stable international standard protocols in conformance with the OSI Reference Model layer definitions have been published by various standards organizations. A system should adhere to a commercial implementation of a middleware standard. transactional data, content data, and historical data. actual live data and connections with consumers. would include credit cards, debit cards, store/loyalty cards, smart cards, user identity credentials (identity cards, passports, The geographically divided infrastructure described above forms the foundation for an overall communications framework. Every view has an associated viewpoint that describes it, at least implicitly. Data Architecture C. Application Architecture D. Technology Architecture E. Pattern Architecture. The Process/Event/Control/Product catalog contains the following metamodel entities: The Contract/Measure catalog provides a listing of all agreed service contracts and the measures attached to those establishing traceability. firewalls and demilitarized zones. A further benefit of a well-defined modular system is that the modules defined within it may be re-used in the same or on other projects, cutting development time dramatically by reducing both development and testing effort. The Business Service/Function catalog can be used to identify capabilities of an organization and to understand the level that governance is applied to the functions of an organization. Depending upon the organization, this may also include location or business domain-specific standards Information-intensive systems also tend to require information from other systems and, if this path of information passing is automated, usually some mediation is required to convert the format of incoming information into a format that can be locally used. The main tool of the controller is radar. The Requirements catalog captures things that the enterprise needs to do to meet its objectives. In this example, one viewpoint is the description of how the user sees the system, and the other viewpoint is how the developer sees the system. As explained in Part II: Architecture Development Method (ADM), the development of architecture views is an iterative process. applications, information management applications, and business warehouse applications. ", etc. For many architectures, a useful viewpoint is that of business domains, which can be illustrated by an example from The Open Group itself. In addition, Microsoft's Object Linking and Embedding (OLE) standard for Windows is an example of an implementation of distributed object management, whereby any OLE-compatible application can work with data from any other OLE-compatible application. The two frameworks. Entity on the other axis. It should also ease the pain of maintaining all the interfaces. It provides a detailed model of architectural work products, including Deliverables, Artifacts within deliverables, and the Architecture Building Blocks (ABBs) that deliverables represent. can be processed to meet the stakeholder needs. should only show intermediary technology where it is architecturally relevant. For example, requirements for an application that services customers can be tested for completeness by verifying exactly which customer types need to be supported and whether there are any particular requirements or restrictions for user types. The purpose of a Goal/Objective/Service diagram is to define the ways in which a service contributes to the achievement of a business vision or strategy. Again, all controllers use a common language derived from the common model in order to capture and framework. For many architectures, a useful architecture viewpoint is that of business domains, which can be illustrated by an example from The communication between a client and a server may involve a local communication between two independent processes on the same machine. to identify synergies across the organization (e.g., multiple organizations attempting to achieve similar objectives), which in The translation of data accesses to objects in the network would be the role of the Direct Data Access layer. Requirements can also be used as a quality assurance tool to ensure that a particular architecture Data-intensive systems can be built with reasonable ease through the use of 4GL tools. constrains (and reduces) how each sees the overall system. This diagram may show details of specification, such as product versions, number of CPUs, etc. The seven layers of the OSI model are structured to facilitate independent development within each layer and to provide for changes independent of other layers. technology. Show the top-level relationships between US/UK geographical sites and business functions. Figure 35-4 depicts an abstract view of an Information Systems Architecture, which emphasizes the fact that an information system from the security perspective is either part of a Local Subscriber Environment (LSE) or a Communications Network (CN). Alternatively, a more pragmatic approach can be equally successful: the architect can create an ad hoc view for a specific system and later consider whether a generalized form of the implicit viewpoint should be defined explicitly and saved in a library, so that it can be re-used. Interoperability comes from shared functionality. This enables the transfer of bits. This is the purpose of the Software Engineering view, which should be developed for the software engineers who are going to develop the system. Fortunately, when controllers talk with pilots, they use a common communication language. later consider whether a generalized form of the implicit architecture viewpoint should be defined explicitly and saved in a Global or Wide Area Networks (WANs) are located throughout the world, providing connectivity for regional and metropolitan networks in the fixed and deployed environment.
