LEGACY EXTERNALIZATION: CAUTION AT INTERSECTIONS
With the aggressive "externalization" of legacy applications to exploit e-business opportunities, users are encountering a major integrity challenge (quality and code/logic) between the front end (new code) and the (legacy) back end. While Mercury and Compuware address testing for each part, multiplatform application logic flows are often not well integrated into the testing process and problem resolution toolkit; this can result in risky, untested gaps. We believe that erstwhile Y2K providers (e.g., Data Integrity, Relativity Technologies) will, during the next 6-12 months, address this requirement by extending multilanguage legacy logic analysis and integrating Java, C, C++, etc., as well as testing. Bottom Line: Externalization efforts that merge new and old code need cross-language testing and analysis tools to provide the reliability and service typical of traditional operations.
