The document discusses John Zachman's Enterprise Information Architecture (EIA) framework. The framework is modeled after the planning process used to design buildings, with different perspectives (scope, business model, system model, etc.) representing different stages of planning and implementation. It structures EIA around 6 perspectives and 6 aspects, forming a matrix with cells describing elements of the enterprise from different viewpoints. The framework helps ensure all relevant considerations are addressed from the business goals to the technical implementation.
