Then, we examined supporting business processes to determine the foundation of the overall architecture and develop a logical data model. Using this information, we constructed a three-tier architecture model that facilitates delivery of source data, supports the data warehouse and data marts, and accommodates presentation tools that simplify user access. The next step was to choose presentation facilities to give Cat Logistics and HMEP quick response to business questions. Finally, since most users are located in Europe, we adopted a web-enabled integration approach that allows worldwide access to the system. It provides a consistent, clean, single source of information that facilitates delivery to all user-access and presentation tools.
Users can access summary information across all data hierarchy levels.
Users have access to information that previously was unavailable-including data on profit and cost drivers that directly impacts the business. Because all users are working with the same information, they can focus on using it to increase productivity and make strategic decisions-not on writing and maintaining complex reporting processes that deliver inconsistent and inaccurate results. Quick, easy access. Information that used to take hours or days to report is available at users' fingertips-literally. They don't have to trudge through volumes of data, which boosts productivity.
