This report describes an architectural references model that can be used to decompose distributed data sharing systems into component parts. The purpose is to formalize interfaces so as to facilitate the placement of components on different nodes of a distributed system. It does this by describing data access functionality in terms of two dimensions a data abstraction dimension that involves a step by step transformation between the physical stored view of data and the end user displayed logical view of data, and a spatial dimension that involves the interaction between transactions and between pieces of data on different nodes.
