Aggregate navigation describes the functionality that BI systems have to use summary level data instead of detail level data for faster data access and report performance. When using Oracle Business Intelligence 11g and Oracle Database 11g, we can choose which “engine” we want to handle summary management and the navigation between different levels of granularity: the BI Server, or the Oracle Optimizer. Both methods support full summary management functionality, and either one is robust enough for an enterprise data warehouse. So which one should we choose? This presentation will walk the participants through both options, and investigate the different design paradigms that may favor one implementation over the other.
