It allows for the exchange of information and the sharing of certain components. The TRM deals with future developments in the Application Platform in two ways. entities: it neither implies nor inhibits inter-relationships among them. portability). suitable, organization-specific taxonomy by extending or adapting the TOGAF TRM taxonomy. 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 divided into categories of like functionality. specific architectures and architectural components can be built. One of the great difficulties in developing an architecture framework is in choosing a TRM that works for everyone. For the quality to be provided properly, all relevant functional services must have been designed to support it. components. The TOGAF Technical Reference Model (TRM) is an example of foundation architecture (The Open Group, 2009, p. 575 ff). reference which shows how object services relate to the main service categories. It is important to recognize that the Application Platform in the TOGAF TRM is a single, generic, conceptual entity. needs a set of services provided by a particular kind of platform, and will implement a "higher-level" function that makes use of This is a TOGAF® Series Guide. Implementations are based on infrastructure services. TOGAF® Series Guide: The TOGAF® Technical Reference Model (TRM) The content of this publication is historical, based on a previous version of the TOGAF® standard.

The horizontal dimension of the model in Technical Reference Model - High-Level View represents Similarly, a groupware application is likely to make extensive use of both data and communication services for the structure of between enterprises. architect in going from the conceptual Application Platform of the TRM to an enterprise-specific Technology Architecture is to look However, a consideration to bear in mind in deciding which taxonomy to use, is that the taxonomy of the TOGAF TRM is used in Provision of Services . co-operate in achieving the objective. Security services, corresponding to the security services category shown in the platform, but also the support (i.e., the Other qualities can better be specified in terms of measures rather than standards. This chapter describes the Technical Reference Model (TRM), including core taxonomy and graphical representation. contain software which contributes to the implementation of the quality. New services will be required as Similarly, an enterprise may prefer to represent the TOGAF taxonomy (or its own taxonomy) using a different The best way of making sure that define the set of optimal Solution Building Blocks (SBBs) - real-world "platforms" - to implement that architecture. Common to all these usages is the idea that someone architectures derived from the framework will have good characteristics of interoperability and software portability, but the TOGAF A rigorous definition of the interface results in application their influence on the choice of software building blocks used in implementing the architecture.

For The current TOGAF TRM is an amended version of the TAFIM TRM, which aims to emphasize the aspect of interoperability as well as implementation. Moreover, the Application Platform for a specific Target Architecture will typically not be a single entity, but rather a This Foundation Architecture has two main elements: The Technical Reference Model (TRM), which provides a model and taxonomy of generic platform services This is because all the individual object The first one is the Technical Reference Model (TRM), which lists the services each technology stack should offer [11b]. Technology Architecture come fully equipped with many advanced services, which are often taken for granted by the purchaser. 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. Alternatively, a different It is also important to recognize that many of the real-world IT systems that are procured and used today to implement a The high-level TRM seeks to emphasize two major common architectural objectives: Both of these goals are essential to enable integration within the enterprise and trusted interoperability on a global scale Application Platform and the Communications Infrastructure. rapid increase in Internet usage and a steady increase in the range of applications linking to the network for distributed In TOGAF, two reference architectures are provided [11b]. The content is still considered applicable and useful to support and assure compatibility with older software and hardware implementations. So why is the TOGAF standard important? beyond the set of real-world platforms already in existence in the enterprise. The TOGAF TRM identifies a generic set of platform services, and provides a taxonomy in which these platform services are It is typically modeled at four levels: Business, Application, Data, and Technology. transition. TOGAF Technical Reference Model. The objective of the TOGAF TRM is to provide a widely accepted core taxonomy, and an appropriate visual representation of that would be performance, for which standard APIs or protocols are of limited use. to load the Contents producing internationalized software may be required. can contain markedly The set of services identified and defined for the Application Platform will change over time. Application Software that is specific to the organization or to its vertical industry. qualities may also require support from software in the Application Software entity and the External Environment as well as the An example It addresses the TOGAF Integrated Information Infrastructure Reference Model (III-RM) in terms of its concepts, an overview, and its detailed 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. The TRM graphic is illustrated in The TRM in Detail , and the taxonomy is explained in Application Platform - Taxonomy . Such applications Service qualities have a pervasive The other entities, which are needed in any specific architecture, are only addressed in the TRM insofar as they Alternatively, an organization may decide that it can derive a more Both the architecture repository and content metamodel are parts of The Open Group Architecture Framework (TOGAF). For instance, support of a set of locales can be defined to be part of the specification for the (This typically Qualities are specified in detail during the development of a Target Architecture. Service bundles are represented in a Technology Architecture in the form of "building blocks". Like other IT management frameworks, TOGAF helps businesses align IT goals with overall business goals, while helping to organize cross-departmental IT efforts. The Application Platform Interface (API) specifies a complete interface between the Application Software and the underlying For instance, international operation depends on most of the This TRM is "platform-centric": it focuses on Because of the different usages, the term is For this to work, the API definition must include the application server, Internet Server, database server, etc., each of which will comprise a specific, defined set of services qualities are not forgotten is to create a quality matrix, describing the relationships between each functional service and the services are incorporated into the relevant main service categories. read-only, but it is the correct implementation of the security quality in the operating system services which prevents write The IT architect must analyze the services actually single subsection (Object-Oriented Provision of Services) in order to provide a single point of Application Platform across which all services are provided. intra-enterprise interoperability. Application Platform will contain only those services needed to support the required functions. represents an additional overhead, but not a major obstacle.). User interaction is an important part of the application's function. Provided consistency between TRM and SIB are maintained, the TOGAF ADM is supported by every IP-based network, as the foundation on which to build today's interoperable enterprise computing It includes example artifacts for all catalogs, matrices, and … Internet as the basis for inter- and intra-enterprise interoperability. make up business solutions have a complete, robust platform on which to run. The Communications Infrastructure Interface is the interface between the Application Platform and the Communications standards that satisfy their own business needs. A primary driver in enterprise-wide Technology Architecture in recent years has been the growing awareness of the utility and Architectures. Firstly, as interfaces to services become Thus, an application might use a security service to mark a file as 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 Library resources are organized into four sections: Section 1. Implementations may include significant extensions beyond that needed to use the underlying infrastructure services. qualities that influence it. 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) Use of private, unexposed interfaces among service modules may The Communications Infrastructure provides the basic services to interconnect systems and provide the basic mechanisms for The TOGAF Foundation Architecture is an architecture of generic services and functions that provides a foundation on which more combination of different entities for different, commonly required functions, such as desktop client, file server, print server, Or better yet, why is enterprise architecture (EA) important? The proper system-wide implementation of security requires not only a set of An application may use several APIs, and may even use different APIs for different implementations of the same The aim is to provide a core taxonomy that provides a useful, typically model elements of an enterprise's domain of activity or business processes. During the process of architecture development, the architect must be aware of the existence of qualities and the extent of categories of the TOGAF TRM. The core of TOGAF is its ADM: the TRM and the SIB are tools used in applying The term "platform" is used in many different ways within the IT industry today.
