togaf data architecture artifacts

Hardware security mechanisms include protection against tampering, undesired emanations, and cryptography. Data architecture. helps to define the horizontal scope of change initiatives that may impact particular kinds of applications. How do you assess the impact of new hardware on the system, especially network load? enterprise to understand which services contribute to similar aspects of business performance. as listed in 7.4 Outputs . For example, presentation layer deployment unit is grouped based on the following: There are several considerations to determine how application components are grouped together. airport system with two different stakeholders: the pilot and the air traffic controller. The Project Context diagram is also a valuable tool for project portfolio management and project mobilization. show where applications are used by the end user; the distribution of where the host application is executed and/or delivered in represent ownership and realization of process steps. Process Flow diagrams are useful in elaborating the architecture with subject specialists, as they allow the specialist to describe "how the job is done" for a particular function. More specifically, a viewpoint defines: how to construct and use a view (by means of an appropriate schema or template); the information that should appear in the view; the modeling techniques for expressing and analyzing the information; and a rationale for these choices (e.g., by describing the purpose and intended audience of the view). TOGAF 9 offers enterprise architects predefined artifacts that give business and technical stakeholders very flexible views. The unique tools of the pilot are fuel, altitude, speed, and location indicators. The typical progression is from business to technology, using a technique such as An architecture view will comprise selected parts of one or more models, chosen so as to Users typically interact with applications in a variety of ways; for example: An Application Use-Case diagram displays the relationships between consumers and providers of application services. The need for architecture views, and the process of developing them following the ADM, are explained above. Part of this common language is about location The ISO Reference Model for Open Distributed Processing (RM-ODP) offers a meta-standard that is intended to allow more specific standards to emerge. later consider whether a generalized form of the implicit architecture viewpoint should be defined explicitly and saved in a typically interact with the applications. (This is ISO/IEC 42010:2007 recommended practice.) This matrix should be aligned with and complement one or more platform decomposition diagrams. Most information systems today get information both from their own data stores and other information systems. The Value Stream map includes the following metamodel entities: A diagram showing the relationships between the primary entities that make up the enterprise, its partners, and Once a basic Functional Decomposition diagram has been developed, it becomes possible to layer heat maps on top of The following section describe some of the key issues that the architect might consider when constructing business scenarios. For example, the capabilities to be implemented in different phases of a change completeness. Principles are used to evaluate and agree an outcome for architecture decision points. application-agnostic way as well. This allows effective sizing to be carried out and the IT footprint to be refined. The communication between a client and a server may involve a local communication between two independent processes on the same machine. Architecture) as listed in 10.4 Outputs . The Communications Infrastructure consists of the local, regional, and global transport components. Depending upon the organization, this may also include location or business domain-specific standards The Technology Portfolio catalog contains the following metamodel entities: The purpose of this catalog is to identify and maintain a list of all the technology in use across the enterprise, including hardware, infrastructure software, and application software. A Business Use-Case diagram displays the relationships between consumers and providers of business services. A Business Footprint diagram demonstrates only the key facts linking organization unit functions to delivery services and is utilized as a communication platform for senior-level (CxO) stakeholders. participants understand what the architecture engagement is seeking to achieve and how it is expected that a particular solution and access. customer, stakeholder, or end user. This section presents basic concepts required for an understanding of information system security. roles that use them within the enterprise. Servers are typically implemented as a continuous process waiting for service requests (from clients). Within the Information Distribution layer lies the interface to the "outside world". Complete the sentence: In Phase C, when an existing application is to be replaced, the Data Architecture should. An organization map should provide a chain of command of owners and decision-makers in the organization. The purpose of the Application/Function matrix is to depict the relationship between applications and business functions within the enterprise. The TOGAF® 9 Training Course: Level 2 Certified is a 2-day, interactive, classroom-based learning experience. It allows the system to be used in different environments; for example, the same system should be usable with different sources of data, even if the new data store is a different configuration. In order to achieve the goals of completeness and integrity in an architecture, architecture views are usually A specific activity may use several information domains, each with its own distinct information domain security policy. This view should be developed for the operations, administration, and management personnel of the system. Business functions are performed by organizational units. 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 Through this process, each process step can become a more fine-grained function and can then in turn be elaborated as a process. In TOGAF, architecture views are the key artifacts in an architecture description. of the system architecture. In addition to these core services, security management requires event handling, auditing, and recovery. Diagrams are renderings of architectural content in a graphical format to allow stakeholders to retrieve the The term "distributed DBMS" implies homogeneity. Communications services are performed at one or more of these architectural levels within the geographical components. For example, the diagram can via some form of API or web service. This diagram is developed to address the concerns of business stakeholders. Computational completeness: a general-purpose language (such as Ada, C, or C++) is computationally complete. However, there are things that are shared, such as descriptions of the processes that are enabled by the system and/or communications protocols set up for users to communicate problems directly to development. The purpose of the Data Entity/Data Component catalog is to identify and maintain a list of all the data use across It is useful in systems upgrade or application consolidation projects. It does not describe the The purpose of the Application Interaction matrix is to depict communications relationships between The Platform Decomposition diagram depicts the technology platform that supports the operations of the Information Systems Architecture. The data entities in a package/packaged services environment can be classified as master data, reference data, transactional data, content data, and historical data. help in assessing its effectiveness; i.e., does the architecture viewpoint cover the relevant stakeholder concerns? This client establishes the look-and-feel of the interface; the server (presentation tier) actually performs the tasks by manipulating the display. The slave computers perform application processing only when directed to by the master computer. Services are associated with the drivers, goals, objectives, and measures that they support, allowing the enterprise to understand which services contribute to similar aspects of business performance. The key purpose of the Logical Data diagram is to show logical views of the relationships between critical data Applications will create, read, update, and delete data within other applications; this will be achieved by some A distributed, heterogeneous database system is a set of independent databases, each with its own DBMS, presented to users as a single database and system. information format or content, but will address protocol and capacity issues. This step requires an update of the status to "deployed" of SBBs, with the system identifier of where the building block was deployed. Some of the functions and services performed by those organizational units will be supported by applications. A "view" is a representation of a whole system from the perspective of a related set of concerns. The interface to the human user of a tool is typically close to the model and language associated with the viewpoint. In our example, one (This is one way of establishing a library of viewpoints initially.). So, in essence, each architecture viewpoint is an abstract model of how all the stakeholders of a particular type - It enables more detailed impact analysis when planning migration stages, and analyzing opportunities and solutions. Part 1: Answers to nine general questions about methods. The diagram shows how the logical entities are to be physically realized by application components. It is typically modeled at four levels: Business, Application, Data, and Technology. diagram addresses the following: The organization and grouping of deployment units depends on separation concerns of the presentation, business (referred to as the baseline in the ADM) and the target environment. This view is concerned primarily with information-intensive systems. specialist to describe "how the job is done" for a particular function. An information domain security policy is the statement of the criteria for membership in the information domain and the required protection of the information objects. where appropriate. Outer boxes = locations; inner boxes = business functions. Standardization of security management functions, data structures, and protocols will enable interoperation of Security Management Application Processes (SMAPs) across many platforms in support of distributed security management. The Application Migration diagram identifies application migration from baseline to target application components. Communication should be logical and In this model the remote procedure calls typically used for communication in the client/server and other distributed processing models are replaced by messages sent to objects. A definitive listing of end-to-end collections of value-adding activities that create an overall result for a The two frameworks. This reveals areas where new technology can contribute to the function or efficiency of the new architecture, and how different types of processing platform can support different parts of the overall system. is documented in a partially specialized language, such as "pilot-speak" versus "controller-speak". level that governance is applied to the functions of an organization. For many architectures, a useful viewpoint is that of business domains, which can be illustrated by an example from The Open Group itself. The transport components correspond to a network management structure in which management and control of network resources are distributed across the different levels. Data protection is necessary to prevent unauthorized users from understanding the content of the database. The concepts discussedin this section have been adapted from more formal definitions contained in ISO/IEC/IEEE 42010:2011 and ISO/IEC/IEEE 15288:2015.They are illustrated in Figure 31-1. The corresponding architecture view of The Open Group (in 2017) is shown in Figure 31-2 demonstrate to a particular stakeholder or group of stakeholders that their concerns are being adequately addressed in the design If you want to become an Enterprise Architect and take part in building an enterprise's strong foundation, then now is the time to start learning some key TOGAF architecture principles. The source system uses this model to convert its information into data to be passed, and the destination system uses this same model to convert the received data into information it can use. Hence, the data in a repository is much more extensive than that in a DD/DS, which generally defines only the data making up a database. requirements. A vertical partitioning puts some fields and the associated data on one platform and some fields and the associated data on another platform. The Examples of this Now let us map this example to the Enterprise Architecture. The course focuses on the practical application of the TOGAF® 9.2 framework, building on the foundational knowledge and comprehension of Level 1, using practical scenarios to enforce concepts. architecture viewpoint. A Project Context diagram shows the scope of a work package to be implemented as a part of a broader transformation of information. The main tool of the commonality, or impact. The purpose of the Product Lifecycle diagram is to assist in understanding the lifecycles of key entities within The Network and Communications diagram will take logical connections between client and server components and In particular, the security management function controls information needed by operating system services within the end system security architecture. In most cases, regional and metropolitan networks are used to connect local networks. typically the start point of the Application Architecture phase. TOGAF ®9.1 in Pictures www.orbussoftware.com ... previous architecture work stored as artifacts and building blocks in a repository, but they can also be pulled from industry standards. concepts can be summarized as: The content metamodel is used as a technique to structure architectural information in an ordered way so that it The architecture viewpoint of the developer is one of productivity and tools, and doesn't include things such as The communications network provides the means by which information is exchanged. — Data Flow Diagram. Further examination in the Business Architecture will discover the “Order” is defined as depicted in Figure 2. This diagram can be elaborated or enhanced as detailed as necessary. Building blocks give the planner a sense of the risk involved; if many ABBs or SBBs exist that match the concept, the risk is lower. The Contract/Measure catalog contains the following metamodel entities: The purpose of this matrix is to depict the relationship interactions between organizations and business functions across the enterprise. The approach requires: This approach does not contrast with client/server or peer-to-peer models but specifies a consistent interface for communicating between co-operating platforms. business functions within the enterprise. Building blocks that are put into production get marked appropriately. Standard interfaces will be provided to connect regional and metropolitan networks and end devices. Architectural artifacts are created in order to describe a system, solution, or state of the enterprise. Global or Wide Area Networks (WANs) are located throughout the world, providing connectivity for regional and metropolitan networks in the fixed and deployed environment. In the current state of the market, different tools normally have to be used to develop and analyze different views ...
