service categories which are considered to be generic in its own vertical market segment. "security awareness") of software in other parts of the TRM. The major categories of services defined for the Application Platform are listed below. Application Platform will contain only those services needed to support the required functions. 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. 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… Human actors within these organizations include: users, customers, owners, … often qualified; for example, "application platform", "standardized" and "proprietary platforms", "client" and "server In building an architecture, users of TOGAF should assess their own requirements and select the services, interfaces, and interoperable, and general-purpose to be potentially useful to a broad range of enterprise IT users. portability, provided that both platform and application conform to it. TOGAF helps businesses define and organize requirements before a project starts, keeping the process moving quickly with few errors. service categories in the same way, both providing facilities and needing their co-operation for localization of messages, fonts, The content is still considered applicable and useful to support and assure compatibility with older software and hardware implementations. Business applications are applications that are specific to a particular enterprise or vertical industry. For the quality to be provided properly, all relevant functional services must have been designed to support it. on top of the Application Platform, that is needed to address the enterprise's business requirements. The ACRA, depicted in Fig. ), product suppliers, system integrators, and regulators (typically government departments or government-sponsored organizations). those services. One of the key tasks of the IT viewpoint of the TOGAF TRM, the Application Platform contains all possible services. TOGAF Reference Architectures. include: Over time, particular business applications may become infrastructure applications, if they become sufficiently ubiquitous, 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. Moreover, the Application Platform for a specific Target Architecture will typically not be a single entity, but rather a diversity, and the shape of the model is intended to emphasize the importance of minimum diversity at the interface between the typically model elements of an enterprise's domain of activity or business processes. This enables the integration of both processes in the architecture. So why is the TOGAF standard important? So why should you care about reference architecture? Private interfaces represent a risk that should be highlighted to facilitate future In the same way, an organization may prefer to depict the TOGAF taxonomy (or its own taxonomy) using a different form of TRM transition. This section describes the role of the TRM, the components of the TRM, and using other TRMs. may over time come to be regarded as infrastructure applications, so infrastructure applications are normally candidates for Preliminary Phase Phase A: Architecture Vision artefacts Phase E Opportunities and Solutions Artefacts Principles Catlaog Stakeholder Map Matrix Value Chain Diagram Solution Concept Diagram The service qualities presently identified in the TRM taxonomy are: The TOGAF document set is designed for use with frames. new technology appears and as application needs change. This is causing a Application Software that is specific to the organization or to its vertical industry. capability should include fourth generation language-like capabilities that enable the use of programming logic within It allows for the exchange of information and the sharing of certain components. TOGAF® helps practitioners avoid being locked into proprietary methods, utilize resources more efficiently and effectively, and realize a greater return on investment. platform must support the API as specified, and the application must use no more than the specified API. List for that Part of the TOGAF document into the Secondary Index frame in the left margin. Templates provided by The Open Group Adoption Strategies Working Group to accompany W102 and W103. Service qualities have a pervasive Platform. supported by every IP-based network, as the foundation on which to build today's interoperable enterprise computing User interaction is an important part of the application's function. It is important to recognize that the Application Platform in the TOGAF TRM is a single, generic, conceptual entity. This chapter describes the Technical Reference Model (TRM), including core taxonomy and graphical representation. An application may use several APIs, and may even use different APIs for different implementations of the same architect in going from the conceptual Application Platform of the TRM to an enterprise-specific Technology Architecture is to look enterprise adopting a different taxonomy will need to reflect its taxonomy in its own SIB), there is no problem with using other many architectures will not include all of the services discussed here, and many will include additional services to support of requirements for Technology Architecture services, and the selection of standards for the Application Platform will be 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 For example, a workflow opaque transfer of data. The TOGAF Enterprise Continuum is a 'virtual repository' of all the architecture assets - models, Patterns, architecture descriptions and other artifacts - that exist both within the enterprise and in the IT industry at large, and that the enterprise considers itself to have available for … qualities that influence it. No claims are made that the chosen categorization is the only one possible, or that it represents the optimal choice. For example, a different taxonomy may be embodied in the legacy of previous architectural work by an organization, and the ACRA was proposed as the foundation for realizing the Autonomic Computing vision [28].In this vision, ACRA-based autonomic systems are defined as a … services are incorporated into the relevant main service categories. Reference Model (Showing Service Categories) . TOGAF is a high-level approach to design. The underlying aim in this approach is to ensure that the higher-level building blocks which rapid increase in Internet usage and a steady increase in the range of applications linking to the network for distributed A primary driver in enterprise-wide Technology Architecture in recent years has been the growing awareness of the utility and This is a TOGAF® Series Guide. organization wishing to use TOGAF entirely for internal purposes (for example, to develop an information system architecture for standardized, functionality which previously formed part of the Application Software entity migrates to become part of the A rigorous definition of the interface results in application This TRM is "platform-centric": it focuses on ... TOGAF ® Reference Models Level 1; During the process of architecture development, the architect must be aware of the existence of qualities and the extent of An important contribution of this reference architecture is the provision of terminology and checklists [Kel11]. 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 that of portability. Usually this means that the software building blocks that implement the functional services The other entities, which are needed in any specific architecture, are only addressed in the TRM insofar as they qualities are not forgotten is to create a quality matrix, describing the relationships between each functional service and the In practice, A particular organization may need to augment this set with additional services or 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®. The license is free to any Technical Reference Model - High-Level View seeks to reflect the increasingly important role of the syntax and semantics of not just the programmatic interface, but also all necessary protocol and data structure definitions. graphic, which better captures legacy concepts and proves easier for internal communication purposes. represents an additional overhead, but not a major obstacle.).

TOGAF® 9 Template Artifacts and Deliverables, Set 2. In particular, the model emphasizes the importance of focusing on the core set of services that can be guaranteed to be The content fra… It may be used freely by any organization wishing to develop enterprise architecture for use within that organization. TOGAF Architecture Development Method (ADM) This section describes, for each phase of the TOGAF ADM, what the architect should consider particularly when looking to apply the principle of service-orientation, and how this affects the outputs of the phase. It describes the TOGAF Technical Reference Model (TRM), including the core taxonomy, graphical representation, and the detailed platform taxonomy. 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 influence the application platform. It is a real, measurable … 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. Such applications and the physical Communications Infrastructure, including switches, service providers, and the physical transmission media. This section describes the TRM in detail, including platform service categories and external environment sub-entities. The TOGAF TRM identifies a generic set of platform services, and provides a taxonomy in which these platform services are A key goal of architecture development is for service modules to be capable of replacement by other modules The diagram says nothing about the detailed relationships between the entities; only that they exist.
