Oracle Database 12c introduced two new histograms – Top Frequency and Hybrid – that can dramatically improve the accuracy of cardinality estimates, construction of better execution plans, and speedier access to skewed data sources.  This presentation will offer real-world examples of how best to deploy these features, including actual metrics that illustrate the improvement in…

The join is probably the most fundamental operation to be applies to relational database data. This presentation takes a step back from the techniques that are familiar to many, and looks at different types of joins and the implications behind their use. A discussion of the traditional Oracle syntax versus ANSI syntax will be conducted…
