Slicing functional components from data-intensive business programs

Abstract

Functional components are program components which provide a set of tightly-coupled program functionalities. As functionalities embody domain knowledge, these components provide a basis for the recovery of reusable program components. We augment general program slicing to handle the interaction among input/output statements operating on a database. With the use of augmented program slicing, an approach, called functional slicing, is proposed for computing the functional components of a program.
