The double wave data warehouse hardware architecture for business intelligence implementation

Abstract

South Africa is a developing country, which since 1994 has gone through a process of privatisation of some of its state departments. The Department of Posts and Telecommunications was one of those government departments. During this transition period, BI played a critical role in measuring the performance of the newly formed telecommunications company, against targets set by government. The new telecommunications company had to meet the targets set, whilst also preparing for future competition. This paper discusses the new DWDW lifecycle model that was developed to deal with the challenges faced whilst implementing the BI solution. The new DWDW lifecycle model called for a different hardware architectural design. The aim of this paper is to explain this new architectural design.
