Abstract

Recently, the research and practical efforts have intensified in the area of Information Systems (IS) supporting data and application evolution. The need to support IS evolution is caused by a variety of reasons including dynamicity of data sources, changing processing requirements, and using new technologies. In this paper we concentrate on evolution of IS data repositories caused by dynamicity of data sources. Our approach is to capture changes of various data hierarchies and use them as rules to implement evolution of IS data repository. Evolution of hierarchies can be categorized into hierarchy creation, hierarchy deletion, and hierarchy modification.
