Abstract

Organizations today are facing increasingly complex challenges in terms of management and problem solving in order to achieve their operational goals. This situation compels people in those organizations to utilize analysis tools that can better support their decisions. Business intelligence comprises a collection of methodologies, processes, architectures, and technologies that transform raw data into meaningful and useful information for decision making. Business intelligence and decision-support systems provide assistance to managers at various organizational levels for analyzing strategic information. These systems collect vast amounts of data and reduce them to a form that can be used to analyze organizational behavior. This data transformation comprises a set of tasks that take the data from the sources and, through extraction, transformation, integration, and cleansing processes, store the data in a common repository called a data warehouse . Data warehouses have been developed and deployed as an integral part of decision-support systems to provide an infrastructure that enables users to obtain efficient and accurate responses to complex queries.
