Snippet from Wikipedia: Enterprise architecture

Enterprise Architecture (EA) is a discipline that: i) defines, organises, standardizes, and documents the whole architecture and all important elements of the respective organisation, covering relevant domains such as business, digital, physical, or organisational; and ii) the relations and interactions between elements that belong to those domains, such as processes, functions, applications, events, data, or technologies.
