The Oracle OLAP option is a full-featured on-line analytical processing (OLAP) server embedded within the Oracle Database. The Oracle OLAP option can be used to improve SQL- based business intelligence tools and applications by improving query performance and enriching them with analytic content. As an OLAP solution that is deeply embedded in the Oracle Database, the Oracle OLAP option allows centralized management of data and business rules in a secure, scalable and enterprise-ready platform New in Oracle Database 11g is support for OLAP-based materialized views which can replace the need to replace, perhaps thousands of materialized views into a single, easy-to-manage. | Citation analysis of database publications Erhard Rahm Andreas Thor University of Leipzig Germany rahm thor @informatik.uni-leipzig.de Abstract We analyze citation frequencies for two main database conferences SIGMOD VLDB and three database journals TODS VLDB Journal Sigmod Record over 10 years. The citation data is obtained by integrating and cleaning data from DBLP and Google Scholar. Our analysis considers different comparative metrics per publication venue in particular the total and average number of citations as well as the impact factor which has so far only been considered for journals. We also determine the most cited papers authors author institutions and their countries. 1. Introduction The impact of scientific publications is often estimated by the number of citations they receive i.e. how frequently they are referenced by other publications. Since publications have associated authors originating institutions and publication venues e.g. journals conference proceedings citations have also been used to compare their scientific impact. For instance one commonly considered indicator of the quality of a journal is its impact factor AM00 . The impact factors are published yearly by Thomson ISI in the Journal Citation Report JCR by counting the citations from articles of thousands of journals. However database research results are primarily published in conferences which are not covered by the JCR citation databases. The two major database conferences SIGMOD and VLDB receive and publish many more papers than the two major journals ACM TODS and VLDB Journal VLDBJ . Furthermore these conferences are more than twice as selective as the journals with acceptance rates for research papers of 15-20 vs. 35-45 Be05 . The number of conference submissions has increased significantly in the last five years Be05 underlining the high scientific importance of conferences. The tremendous scope of new scientific archives like Google Scholar makes it possible to freely access .
