Bank application reengineering and conversion at the Union Bank of Switzerland

摘要

The author describes a large software reengineering project at the Union Bank of Switzerland. Seven bank applications with 203 programs and 432 files were renovated and migrated from a UNIVAC-494 to a UNISYS-1100. The programs were restructured to fit a JSP-DELTA generator. The data were remodeled to fit into a CODASYL database with a data dictionary and a common COPY library.
