Processes in computer systems are often intimately involved with various data abstractions that occur in the systems. The specification of such processes should state the nature of this involvement. This note focuses on a special kind of process, called a realization process, and its specification because it appears to capture the interplay between concurrency and abstraction in a natural way. A realization process has two important properties: it is transparent to the abstract space and it is serializable with processes at the abstract level. Transparency and serializability are the main specifications of realization processes. These concepts are illustrated by an example of the kind of realization processes found in actual computer systems which serves to motivate the discussion.
