It may be tailored to the organization's needs and is then employed to manage the execution of architecture planning activities. [18] The process is iterative and cyclic.
External schema is extracted from a federated schema, and is defined for the users/applications of a particular federation. [3] While accurately representing the state of the art in data integration, the Five Level Schema Architecture above does suffer from a major drawback, namely IT imposed look and feel.
ISO/IEC/IEEE 42010:2011 defines requirements on the description of system, software and enterprise architectures.It aims to standardise the practice of architecture description by defining standard terms, presenting a conceptual foundation for expressing, communicating and reviewing architectures and specifying requirements that apply to architecture descriptions, architecture frameworks and ...
Identity federation comes in many flavors, including "user-controlled" or "user-centric" scenarios, as well as enterprise-controlled or business-to-business scenarios. Federation is enabled through the use of open industry standards and/or openly published specifications, such that multiple parties can achieve interoperability for common use-cases.
Enterprise Application Integration is related to middleware technologies such as message-oriented middleware , and data representation technologies such as XML or JSON. Other EAI technologies involve using web services as part of service-oriented architecture as a means of integration. Enterprise Application Integration tends to be data centric.
