Information technology architecture

Information technology (IT) architecture is the process of development of methodical information technology specifications, models and guidelines, using a variety of information technology notations, for example Unified Modeling Language (UML), within a coherent information technology architecture framework, following formal and informal information technology solution, enterprise, and infrastructure architecture processes. These processes have been developed in the past few decades in response to the requirement for a coherent, consistent approach to delivery of information technology capabilities.
