Abstract

A distributed system modeler for modeling a distributed system architecture. The distributed system modeler includes logic for receiving interdependency information specifying interdependencies between a plurality of data objects and programs, logic for defining a plurality of modules, wherein each module of the plurality of modules represents a different grouping of a portion of the plurality of data objects and programs, logic for assigning the modules to nodes in a distributed system, and logic for assigning a distributed transfer methodology between modules in the distributed system. The distributed system modeler includes logic for generating impact analysis criteria defining a quality of said distributed system. The impact analysis criteria includes performance metrics, conflict metrics, data object or program availability metrics, and transaction consistency metrics. The distributed transfer methodology includes a distributed transaction methodology, a synchronous replication methodology, an asynchronous replication methodology, and a procedural replication methodology.
