Case studies of system architectures that use COBOL assets

The Common Business Oriented Language (COBOL) was developed as a programming language for business transactions. For a long time, it has been a major programming language for mission-critical systems because of its high reliability and compatibility ensured through international standards. NetCOBOL is a COBOL development environment offered by Fujitsu that supports quick construction and stable operation of mission-critical systems in cooperation with Java and Visual Basic. It achieves this by using existing COBOL assets as well as many supporting tools and standard development styles based on technologies that comprise Fujitsu's Systems Development Architecture & Support facilities (SDAS). In this paper, we introduce case studies of the architectures of three systems that use COBOL assets. The first system, at Seikodo Co., Ltd., is based on a combination of Java and COBOL. The second, at Meitetsucom Co., Ltd., is a NET Framework-based system linked with a combination of Visual Basic and COBOL. The third, at Presidential Life, is a NET Framework-based system built using COBOL.
