quality has a unique influence on one particular service category. services are incorporated into the relevant main service categories. typically model elements of an enterprise's domain of activity or business processes. 2.9, provides a reference architecture to organize and orchestrate self-adaptive (i.e., autonomic) systems using autonomic elements, where an autonomic element is basically an implementation of the MAPE-K model. platform and the external environment. Reference Model (Showing Service Categories), Communications Infrastructure Interface (, Patient record management services used in the Medical industry, Inventory management services used in the Retail industry, Geological data modeling services used in the Petroleum industry. Besides the platform service categories delineated by functional category, service qualities affect Information Systems Detailed Technical Reference Model (Showing Service Categories) is only a depiction of the TRM structuring the TOGAF SIB, the database of all industry standards endorsed by The Open Group which is available for populating an architecture. A primary driver in enterprise-wide Technology Architecture in recent years has been the growing awareness of the utility and can contain markedly architect in going from the conceptual Application Platform of the TRM to an enterprise-specific Technology Architecture is to look an enterprise, different systems purchased for similar functions (such as desktop client, print server, etc.) (This typically It is typically modeled at four levels: Business, Application, Data, and Technology. on top of the Application Platform, that is needed to address the enterprise's business requirements. TOGAF stands for The Open Group Architecture Framework.The most recent version is TOGAF 9.1, published in December 2011. You must have JavaScript enabled in your browser to utilize the functionality of this website. In the same way, an organization may prefer to depict the TOGAF taxonomy (or its own taxonomy) using a different form of TRM An important contribution of this reference architecture is the provision of terminology and checklists [Kel11]. In practice, The TRM deals with future developments in the Application Platform in two ways. Technology Architecture come fully equipped with many advanced services, which are often taken for granted by the purchaser. Any differences from the TOGAF TRM taxonomy would need to be catered for when using the TOGAF SIB. application may use platform services such as messaging or transaction processing to implement the flow of work among tasks. service categories in the same way, both providing facilities and needing their co-operation for localization of messages, fonts, A second article will focus on key design ideas for such a reference architecture, followed by a third article to describe its essential capabilities. In this article, I'll share guiding principles for a reference architecture for the Healthcare industry. Usually this means that the software building blocks that implement the functional services In particular, the model emphasizes the importance of focusing on the core set of services that can be guaranteed to be One of the key tasks of the IT The following sections discuss in detail each element of the TRM illustrated in Detailed Technical It addresses security and risk management at a conceptual level, which matches with the way that TOGAF defines architecture. In TOGAF, two reference architectures are provided [11b]. The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture today that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. Templates provided by The Open Group Adoption Strategies Working Group to accompany W102 and W103. influence the application platform. viewpoint of the TOGAF TRM, the Application Platform contains all possible services. beyond the set of real-world platforms already in existence in the enterprise. Implementations are based on infrastructure services. : Analyze existing documents Determine domain specific processes Determine domain specific layers Extension of existing information Create submission document Analyze resulting documents of LEAF Analyze additional documents Generalize and anonymize Request further … valid whatever the choice of specific taxonomy, TRM graphic, or SIB toolset. This section describes the major elements of the TRM. platform must support the API as specified, and the application must use no more than the specified API. Architects executing the Architecture Development Method (ADM) will produce a number of outputs as a result of their efforts, such as process flows, architectural requirements, project plans, project compliance assessments, etc. "security awareness") of software in other parts of the TRM. migration from other architectures. consistent, structured definition of the Application Platform entity and is widely acceptable. environments. The major categories of services defined for the Application Platform are listed below. Detailed Technical Reference Model (Showing Service Categories) captures this concept by depicting the Examples of functional areas which may fall into Application Platform service categories in the future include: A detailed taxonomy of the Application Platform is given in Application Platform - Taxonomy . Avoid lock-in to proprietary solutions b… The ACRA, depicted in Fig. From the Copyright © 1999-2006 The Open Group, All Rights Reserved, Technical Reference Model - High-Level View, Detailed Technical Reference Model (Showing Service Categories), Detailed Technical The Open Groupstates that TOGAF is intended to: 1. Electronic payment and funds transfer services, Management applications, performing general-purpose system and network management functions for the system administrator, Software engineering tools, providing software development functions for systems development staff, Spreadsheet functions, including the capability to create, manipulate, and present information in tables or charts; this Typically, generic reference architectures provide architecture team with an outline of their organization-specific reference architecture that will be customized for a specific organization Does also incorporate OASIS SOA RM definition TOGAF 9.1 Architecture Repository Reference Library (41.3.1) inclusion as infrastructure services in future versions of an IT architecture. form of graphic, which better captures legacy concepts and proves easier for internal communication purposes. In some cases, a service quality affects each of the service categories in a similar fashion, while in other cases, the service graphic, which better captures legacy concepts and proves easier for internal communication purposes. Provided consistency between TRM and SIB are maintained, the TOGAF ADM is the services and structure of the underlying platform necessary to support the use and re-use of applications (i.e., on application Qualities are specified in detail during the development of a Target Architecture. Besides the set of components making up the TRM, there is a set of attributes or qualities that are applicable across the The objective of the TOGAF TRM is to provide a widely accepted core taxonomy, and an appropriate visual representation of that providing the same service functionality via the same service API. They are dealt with in the following order: The detailed TRM recognizes two categories of Application Software: During development of the Technology Architecture, business applications and infrastructure applications are important sources Its main users are planners, managers, and Enterprise Architects. First developed in 1995, TOGAF was based on the US Department of Defense Technical Architecture Framework for Information Management (TAFIM) It is a model used in the field of Enterprise Architecture and, as such, it provides guidelines, templates, models, … Application Platform across which all services are provided. implementation. intended to emphasize minimum diversity at the interface between the Application Platform and the Communications architectural taxonomies and/or graphics with TOGAF. The current TOGAF TRM is an amended version of the TAFIM TRM, which aims to emphasize the aspect of interoperability as well as However, a consideration to bear in mind in deciding which taxonomy to use, is that the taxonomy of the TOGAF TRM is used in foundation on which to build today's interoperable enterprise computing environments. Other architectural models - taxonomies and/or graphics - not only are possible, but may be preferable for some enterprises. Thus, an application might use a security service to mark a file as Firstly, as interfaces to services become the ADM in the development of specific architectures. Some qualities are easier than others to The service qualities presently identified in the TRM taxonomy are: The TOGAF document set is designed for use with frames. In addition to supporting Application Software through the Application Platform Interface (API), services in the Application All data is a concrete, valuable asset to an enterprise. The TOGAF TRM identifies a generic set of platform services, and provides a taxonomy in which these platform services are entities: it neither implies nor inhibits inter-relationships among them. interfaces (Application Platform Interface and Communications Infrastructure Interface). organization may prefer to perpetuate use of that taxonomy. A detailed description of each of these service categories is given in Object-Oriented Alternatively, an organization may decide that it can derive a more Platform. That is, the The underlying aim in this approach is to ensure that the higher-level building blocks which compromise this ability to substitute. It is a real, measurable … Detailed Technical Reference Model (Showing Service Categories) expands on Technical Reference Model - High-Level View to present the service categories of the Application Platform and the However, the various descriptions are also collected into a In the main Contents frame at the top of the page, click the relevant hyperlink (Part I, Part II, etc.) In particular, it centers on the interfaces between that platform and the supported applications, and between the read-only, but it is the correct implementation of the security quality in the operating system services which prevents write The aim is to provide a core taxonomy that provides a useful, The API specifies a complete interface between an application and one or more services offered by the underlying Application taxonomy. For This is a TOGAF® Series Guide. It deals with the complex world of networks Infrastructure applications are applications that have all, or nearly all, of the following characteristics: Examples of applications in this category include: Infrastructure applications have strong dependencies on lower-level services in the architecture. qualities are not forgotten is to create a quality matrix, describing the relationships between each functional service and the A service quality describes a behavior such as adaptability or manageability. So why should you care about reference architecture? In general a requirement for a given level of a particular service quality requires one or more functional service categories to interoperable, and general-purpose to be potentially useful to a broad range of enterprise IT users. Interoperability is a strong requirement. Businesses thrive off change to deliver new products and services to earn revenue and stay relevant. categories of the TOGAF TRM. The Application Platform Interface (API) specifies a complete interface between the Application Software and the underlying Architectures. The content fra… TOGAF® helps practitioners avoid being locked into proprietary methods, utilize resources more efficiently and effectively, and realize a greater return on investment. Service bundles are represented in a Technology Architecture in the form of "building blocks". Provision of Services . The TOGAF TRM focuses on the Application Platform, and the "higher-level function" is the set of Application Software, running This section describes in detail the taxonomy of the TOGAF TRM. The core of TOGAF is its ADM: the TRM and the SIB are tools used in applying the TOGAF TRM taxonomy. For example, a workflow of a Technology Architecture to guide the procurement process, this is invariably what happens. documents, as well as the mechanics of storing and accessing them. Other qualities can better be specified in terms of measures rather than standards. Portability depends on the symmetry of conformance of both applications and the platform to the architected API. The other entities, which are needed in any specific architecture, are only addressed in the TRM insofar as they intra-enterprise interoperability. shows three major entities (Application Software, Application Platform, and Communications Infrastructure) connected by two This is considered further in Communications Infrastructure Interface . would be performance, for which standard APIs or protocols are of limited use. TOGAF Reference Architectures. No claims are made that the chosen categorization is the only one possible, or that it represents the optimal choice. co-operate in achieving the objective. A hardcopy book is also available from The Open Group Bookstore as document G063. The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more qualities may also require support from software in the Application Software entity and the External Environment as well as the TOGAF is a high-level approach to design. One of the great difficulties in developing an architecture framework is in choosing a TRM that works for everyone. The TOGAF Library is a reference library containing guidelines, templates, patterns, and other forms of reference material to accelerate the creation of new architectures for the enterprise. Apart from the need to recognize that the structure embodied in the taxonomy is reflected in the structure of the SIB (so any describe in terms of standards. For this to work, the API definition must include the Infrastructure. The TOGAF Technical Reference Model (TRM) is an example of foundation architecture (The Open Group, 2009, p. 575 ff). example, a typical desktop computer system today comes with software that implements services from most if not all of the service The best way of making sure that Preliminary Phase Phase A: Architecture Vision artefacts Phase E Opportunities and Solutions Artefacts Principles Catlaog Stakeholder Map Matrix Value Chain Diagram Solution Concept Diagram Infrastructure. supported by every IP-based network, as the foundation on which to build today's interoperable enterprise computing The proper system-wide implementation of security requires not only a set of architectures derived from the framework will have good characteristics of interoperability and software portability, but the TOGAF international operation quality. reference which shows how object services relate to the main service categories. Technical Reference Model - High-Level View seeks to reflect the increasingly important role of the It includes example artifacts for all catalogs, matrices, and … Application Platform. This in turn means focusing on the core set of services that can be guaranteed to be supported by every IP-based network, as the between enterprises. Data as an Asset. Common system architectures are one step more specific and typically specify building blocks for particular aspects—for instance, security, system management, or … This is a TOGAF® Series Guide. The IT4IT vision is a vendor-neutral Reference Architecture for managing the business of IT and underpins the important work done with IT frameworks such as TOGAF® 9, COBIT® and ITIL®. service. make up business solutions have a complete, robust platform on which to run. Like other IT management frameworks, TOGAF helps businesses align IT goals with overall business goals, while helping to organize cross-departmental IT efforts. The Open Group Architecture Framework (TOGAF) is a framework - a detailed method and a set of supporting tools for planning, developing, maintaining and gaining value from an Enterprise Architecture. example, such an enterprise-specific model could be derived by extension or adaptation of the TOGAF TRM. Moreover, the Application Platform for a specific Target Architecture will typically not be a single entity, but rather a This chapter describes the Technical Reference Model (TRM), including core taxonomy and graphical representation. two categories of Application Software. The designs below are implemented using the ArchiMate modeling language. The TRM graphic is illustrated in The TRM in Detail , and the taxonomy is explained in Application Platform - Taxonomy . TOGAF helps businesses define and organize requirements before a project starts, keeping the process moving quickly with few errors. The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more specific architectures and architectural components can be built. represents an additional overhead, but not a major obstacle.). This is because all the individual object needed in order to implement an IT infrastructure that meets the enterprise's business requirements in the optimal manner, and The license is free to any suitable, organization-specific taxonomy by extending or adapting the TOGAF TRM taxonomy. For each of the Federal Enterprise Architecture Framework common approach (CA) domains, the template is a guide to the relevant interoperability requirements and artifacts to be incorporated for interoperability. A rigorous definition of the interface results in application Security services, corresponding to the security services category shown in the platform, but also the support (i.e., the needs a set of services provided by a particular kind of platform, and will implement a "higher-level" function that makes use of Application Software that is specific to the organization or to its vertical industry. necessary to support the specific function concerned. For clearing TOGAF certification, there are two key topics. Private interfaces represent a risk that should be highlighted to facilitate future combination of different entities for different, commonly required functions, such as desktop client, file server, print server, User interaction is an important part of the application's function. Common to all these usages is the idea that someone Business applications are applications that are specific to a particular enterprise or vertical industry. Infrastructure applications by definition are applications that are considered sufficiently ubiquitous, interoperable, and Enterprises concerned with the IoT include: vertical area enterprises (manufacturers, municipalities, etc. The horizontal dimension of the model in Technical Reference Model - High-Level View represents diversity, and the shape of the model is specifically contain software which contributes to the implementation of the quality. The Technical Reference Model creates a Navigation diagram, packages, elements and other diagrams that support modeling with the TOGAF Technical Reference Model (TRM) and the Standards Information Base (SIB). capability should include fourth generation language-like capabilities that enable the use of programming logic within operation. In building an architecture, users of TOGAF should assess their own requirements and select the services, interfaces, and IT architectures derived from TOGAF may differ greatly depending on the requirements of the information system. Alternatively, a different It may be used freely by any organization wishing to develop enterprise architecture for use within that organization. This section describes the TRM in detail, including platform service categories and external environment sub-entities. define the set of optimal Solution Building Blocks (SBBs) - real-world "platforms" - to implement that architecture. Indeed, it is important to emphasize that the use of TOGAF, and in particular the TOGAF ADM, is in no way dependent on use of But throughout a business’s lifetime, new systems are created, mergers require system integration or consolidation, new technologies are adopted for a competitive edge, and more systems need integration to share information. Secondly, the TRM may be extended with new service categories as new technology appears. ACRA was proposed as the foundation for realizing the Autonomic Computing vision [28].In this vision, ACRA-based autonomic systems are defined as a … single subsection (Object-Oriented Provision of Services) in order to provide a single point of TRM components sitting on a backplane of qualities. spreadsheets, Decision support functions, including tools that support the planning, administration, and management of projects, Calculation functions, including the capability to perform routine and complex arithmetic calculations, Calendar functions, including the capability to manage projects and co-ordinate schedules via an automated calendar, Document generic data typing and conversion services, Information presentation and distribution functions, Database Management System (DBMS) services, Object-Oriented Database Management System (OODBMS) services, Character sets and data representation services, Remote print spooling and output distribution services, File and directory synchronization services, Computer-aided software engineering (CASE) environment and tools services, Graphical user interface (GUI) building services, Computer-based training and online help services, Identification and authentication services, Availability and fault management services, The ability to offer access to services in new paradigms such as object-orientation. A well-defined and governed EA practice is critically important at an organizationa… The coarsest breakdown of the TRM is shown in Technical Reference Model - High-Level View , which Reference architecture goes one step further by accelerating the process for a particular architecture type, helping to identify which architectural approaches will satisfy particular requirements, and figuring out what a minimally acceptable set of architectural artifacts are needed to meet the “best practices” requirements for a particular architecture. For example, for the management service to be effective, manageability must be a pervasive quality of all platform their influence on the choice of software building blocks used in implementing the architecture. TOGAF Technical Reference Model. Because of the different usages, the term is During the process of architecture development, the architect must be aware of the existence of qualities and the extent of It is important to recognize that the Application Platform in the TOGAF TRM is a single, generic, conceptual entity.
