A survey of data warehouse architectures — Preliminary results

In this abridged version, which is a summary of the authors' study, we present some of our findings for consideration. The principal objective of the study was to investigate empirically the architectures of data warehouse (DW), or more specifically, the types of the architectures and a number of factors, which are believed to influence their selection, were explored. A questionnaire survey, which targeted the information systems managers, was used to collect data from 150 Polish companies about the respondents' firms, the architecture they use, and the factors which influence the selection of the architecture. The findings of the study give us practical insights into DW's field in Poland.
