Abstract

The decisional analysis is a complex, iterative, and exploratory process based on a sequence of queries issued against the data warehouse. The efficiency of the decisional activity depends on the quality of the stored data in the data warehouse, while its effectiveness is related to the analysis tools. In this paper, we discuss both these aspects in the context of a service company, with the aim of analyzing the trend of railway booking data. In particular, the back-end and front-end software solutions of data warehousing implementation are presented, which permit to met the customer needs while preserving the desired requirements of efficiency and effectiveness.
