- W2322381282 abstract "This paper focuses on the challenges faced when building a data warehouse dealing primarily with scientific or engineering data. Successfully applying data warehousing concepts to an engineering-specific database poses some challenges which vary from the usual textbook examples. This, coupled with the introduction of a new database technology (data warehouse), into a large organization with a mature set of users raised an interesting set of challenges. Some of these are highlighted and discussed using the E&P data warehouse at Saudi Aramco as a case study. Sophisticated as it may be, it is a relational database and contains normalized data structures to mainly support day to day operations and reporting needs. It does not lend itself easily to analytical processing. Business is constantly changing. New technologies are being applied as to how exploration for oil and gas is conducted, how the wells are drilled, maintained, and produced and how the reservoirs are managed. These changes must also be reflected in the applications supporting these business functions. Over the decades, we have seen many changes in the IT technologies used to implement software systems. This is also true for the underlying database technologies. With business changing rapidly, asset managers were asking increasingly complex questions. The information was becoming harder to obtain from a relational database. Managers wanted their answers quicker, in order to make the right decisions. Support staff was getting busier and finding it impossible to keep pace with the requests." @default.
