A method for data re-engineering in structured programs

Abstract

While the problem of restructuring control flow in software is fairly well understood, few methods exist for understanding and restructuring the data flow of software. A method of data re-engineering is proposed that combines the theories of data-usage abstractions for system redesign. The principal results of this re-engineering process are the elimination of data-flow anomalies, the reduction of data scope, and the construction of reusable data objects as common services.<>
