Architectures For Integrating Legacy Information Systems With Modern Bar Code Technology
This work reviews alternative solutions for retrofitting existing legacy manufacturing information systems with modern bar code tracking hardware and software. Technologies are divided into one-tier architecturs, which include the use of screen scrapers and terminal emulation software; two-tier architectures, which include the use of standard and custom application program interfaces (API); and three-tier architectures, which discuss the application of standards such as CORBA, DCOM, XML messaging, and application protocols for seamless integration with legacy systems. A case study is provided that describes the use of a two-tier API product for implementing a wireless bar code data capture system with a proprietary warehouse management system. Concluding remarks discuss the importance of emerging three-tier architectures and wireless bar code technologies for business-to-business e-commerce applications. The approaches presented here are consonant with the modern view of considering legacy systems as also providing Web services via multiple channels serving multiple categories of clients. © 2004 Society of Manufacturing Engineers.
