All pilots use this model, and the model has a specific language that is used to capture information and populate the model. An integrated set of specification artifacts " Data Architecture is part of a complete enterprise architecture " What would be in a comprehensive enterprise architecture?! Implementing the necessary security protection in the end system occurs in three system service areas of TOGAF. Its purpose is to quickly on-board and align stakeholders for a particular change initiative, so that all participants understand what the architecture engagement is seeking to achieve and how it is expected that a particular solution approach will meet the needs of the enterprise. or simply could be an informal "eye-chart" providing an overview of the technical environment. So in essence each viewpoint is an abstract model of how all the stakeholders of a particular type - all pilots, or all controllers - view the airport system. The separation of data from process allows common data requirements to be identified which enables resource sharing to be achieved more effectively. Data is the tokens that are stored in databases or other data stores. The relationships depicted by this matrix include: The purpose of the Application Communication diagram is to depict all models and mappings related to communication between applications in the metamodel entity. The tight coupling of the user interface and business logic ensure that they will work well together, for this problem in this domain. These systems can be called "data-intensive". The mapping of the Application Component-Function relationship is an important step as it enables the following to take place: The Application/Function matrix is a two-dimensional table with Logical Application Component on one axis and Function on the other axis. Usually presented in layers, the enterprise data model defines subject areas, business entities, and business relationships. This diagram is really a filter on the Application Communication diagram, specifically for enterprise management class software. Due to the potentially sensitive nature of stakeholder mapping information and the fact that the Architecture Vision phase is intended to be conducted using informal modeling techniques, no specific metamodel entities will be used to generate a stakeholder map. In general these stakeholders are concerned with ensuring that the appropriate communications and networking services are developed and deployed within the system in an optimal manner. The communications network provides the means by which information is exchanged. 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. Once a basic Functional Decomposition diagram has been developed, it becomes possible to layer heat-maps on top of this diagram to show scope and decisions. Communications networks are constructed of end devices (e.g., printers), processing nodes, communication nodes (switching elements), and the linking media that connect them. The diagram covers all aspects of the infrastructure platform and provides an overview of the enterprise's technology platform. While both data architecture and data modeling seek to bridge the gap between business goals and technology, data architecture is about the macro view that seeks to understand and support the relationships between an organization's functions, technology, and data types. Comment goes here. It does not describe the information format or content, but will address protocol and capacity issues. A book is also available (in hardcopy and pdf) from The Open Group Bookstore as document G116. In TOGAF, architecture views are the key artifacts in an architecture description. Gap Analysis. (In other words, the models representing their individual viewpoints partially intersect.) This model could be considered a special case of the client/server model, in which all platforms are both servers and clients. The LSEs by definition are under the control of the using organization. The database can be based on any of the data models discussed above (except the flat file). IBM InfoSphere® Data Architect is a collaborative enterprise data modeling and design solution that can simplify and accelerate integration design for business intelligence, master data management and service-oriented architecture initiatives. There is a single schema (description of the data in a database in terms of a data model; e.g., relational) for a distributed database. Similarly, it might make sense to use the same functionality but with users who need a different user interface. Another approach is to build "mediators" between the systems. TOGAF 9 Artifacts Preliminary Phase Phase A, Architecture Vision • Principles catalog Requirements Management Phase D, Technology Architecture • Technology Standards catalog • Technology Portfolio catalog • System/Technology matrix • Environments and Locations diagram •Platform Decomposition diagram • Processing diagram •Networked This enables a clear view of how the software is hosted, but also enables managed operations staff to understand how that application software is maintained once installed. The following paragraphs describe some of the key issues that the architect might consider when constructing business scenarios. When stakeholders use common tools, such as the radio contact between pilot and controller, a common language is essential. If more than one commercial standard is used (e.g., COM and CORBA), then the system should allow for interoperability between implementations of these standards via the use of commercial bridging software.8 Wherever practical, the interfaces should be specified in the appropriate Interface Description Language (IDL). This step requires access to re-usable SBBs. Extensibility: e.g., a user may define new objects. Example artifacts are as follows: Catalogs: Application Architecture: Applications Portfolio Catalog, Interface Catalog; Business Architecture: Contract-Measure Catalog, Driver-Goal-Objective Catalog, Location Catalog, Organization-Actor Catalog, Process-Event-Control-Product Catalog, Role Catalog, Service-Function Catalog In the peer-to-peer model there are co-ordinating processes. Maintaining all these ICDs is also a challenge. In particular, the security management function controls information needed by operating system services within the end system security architecture. Applications that operate on the data entities include transactional applications, information management applications, and business warehouse applications. The security context is therefore analogous to a common operating system notion of user process space. Stakeholder Management). Most OODBMSs incorporate a general-purpose programming language. It interfaces to the user interface typically through callbacks. If a given system must share information with n other systems, there is the potential need for n2 ICDs. A viewpoint is where you are looking from - the vantage point or perspective that determines what you see. Common sources of data flaws include hardware or software errors, conditions such as electromagnetic interference and flawed designs such as an algorithm prone to miscalculations.
