Code transformation pattern alignments and induction for ERP legacy systems migration

Abstract

In this paper, we present a system that helps us to analyze legacy system reports and to transform these reports using Report Definition Language (RDL) language. The system is semi-automatic, and transforms legacy system reports using programming language specific patterns. Innovations that help us to solve the problem of semi-automatic report generation include a method of legacy system source code analysis, a semi-automatic source code pattern induction algorithm and the use of natural language processing to refine automatically generated report. The system that we suggest has been tested using different types of reports. This helped us determine the set of patterns required for a particular type of legacy system.
