abstraction The technique of providing summarized or generalized descriptions of detailed and complex content. Abstraction, as in “level of abstraction,” can also mean providing a focus for analysis that is concerned with a consistent and common level of detail or abstraction. Abstraction in this sense is typically used in architecture to allow a consistent level of definition and understanding to be achieved in each area of the architecture in order to support effective communication and decision making. It is especially useful when dealing with large and complex architectures, as it allows relevant issues to be identified before further detail is attempted.
