    This document is a proposal for building a data warehouse architecture that will consolidate and transform data into useful information for the purpose of decision-making and for establishing a new function that offers a broad array of decision support services to all units at ABC Retail Chain Corporation. Executives and decision-makers often need information to analyze the past, describe current circumstances, and anticipate the future. Presently, decision-makers across the Institute rely on hard copy reports or Excel Sheets to provide information. Typically, any request for information is forwarded to the operational areas of the Organization, which provide hard copy reports reflecting the data gathered in their functional area. To analyze and transform data into useful information, decision-makers and their staff have to manually re-enter the non-integrated data into their own mini-systems. This type of operation hinders the ability of decision making and the executives are either drowning in too much data with no option to analyze it or too little data, which means they are back to square one and must request additional information. Often executives receive multiple, conflicting information or information that is based on incomplete assumptions about the types of analysis required.…

    Data warehousing and on-line analytical processing (OLAP) are essential elements of decision support, which has increasingly become a focus of the database industry. Many commercial products and services are now available, and all of the principal database management system vendors now have offerings in these areas. Decision support places some rather different requirements on database technology compared to traditional on-line transaction processing applications. This paper provides an overview of data warehousing and OLAP technologies, with an emphasis on their new requirements. We describe back end tools for extracting, cleaning and loading data into a data warehouse; multidimensional data models typical of OLAP; front end client tools for querying and data analysis; server extensions for efficient query processing; and tools for metadata management and for managing the warehouse.…
