The present diploma thesis focuses on the subject matter of large data warehouses under the aspect of their sustainable operation and development, seeking to analyze the key factors which influence the operation of data warehouses at large businesses. The thesis is divided into three main sections, preceded by a short theoretical introduction. The first part aims at explaining and illustrating the architecture of data warehouses, with the bulk of this section being devoted to a description of the key components of data warehouse solutions as a whole, and the various available alternatives for their technical implementation. The second section familiarizes the reader with the manner in which data warehouses are managed and operated, discussing the most important operational tasks in individual sub-sections. The final section focuses on working with client tools within the ETL platform of Informatica Powercenter. This work's original contribution lies in the comparison of how the design of individual components expresses itself in the simplicity and quality of routine operations. As a matter of fact, data warehouses can only be operated as conveniently and competently as they were designed and implemented. In this thesis of mine, I primarily draw on my immediate experience and acquired knowledge from data warehouse operations at a large domestic enterprise.
