AbstractStrategies for migrating data and data processing capabilities from a VMS environment to a Windows environment were investigated. The document discusses the requirements of a viable data migration strategy; some of the more important ones being a unified architecture that is easily scalable, extendible, maintainable, and facilitates the storage and retrieval of data and interactive and batch processing capabilities. It should also provide a common data interface to access backing stores and to isolate application development from backing store implementation details. The document discusses the relative merits of two-tier and three-tier architectures and proposes an architecture that combines the best features of these two approaches. The article presents a prototype analysis database schema and uses this prototype to highlight key concepts. The prototype was useful in illustrating typical operations a user may perform when analyzing a dataset. It was also useful in identifying both the merits and pitfalls associated with particular approaches to solving a problem. The prototype also presented us with benchmarks pertaining to database access speed. After identifying database access bottlenecks with the prototype we developed solutions that significantly improved database access speed.
