Evolution-Oriented User-Centric Data Warehouse

Abstract. Data warehouses tend to evolve, because of changes in data sources and business requirements of users. All these kinds of changes must be properly handled, therefore, data warehouse development is never-ending process. In this paper we propose the evolution-oriented user-centric data warehouse design, which on the one hand allows to manage data warehouse evolution automatically or semi-automatically, and on the other hand it provides users with the under-standable, easy and transparent data analysis possibilities. The proposed approach supports versions of data warehouse schemata and data semantics.
