Explore the module on index types, including beta, bitmap, function based, index organized tables, cluster, and composite indexes, and learn the purpose and advantages of each.
Oracle's bitmap index optimizes queries on low-cardinality columns by converting values into bitmaps of zeros and ones, enabling fast bitwise operations and space-efficient data warehouse performance.
Explore index organized tables stored in a B3 structure where data and index share storage, enabling fast retrieval via the primary key and including non-key columns, with creation constraints.
Explore cluster indexes that cover multiple tables sharing a common column. Create a cluster and a cluster index on the shared department column, and see how it enables efficient queries.
Explore Oracle SQL performance tuning by examining bitmap index, function-based index, index-organized tables, cluster index, and composite index.
Explore how Oracle statistics and histograms influence query optimization, covering cardinality, distinct values, densities, and frequency and height-balanced histograms.
Explore practical Oracle SQL performance tuning with scripts and case studies, covering execution time, cache and disk IO metrics, execution plans, and how to read and reuse past results.
