Access paths are the ways in which data is retrieved from the database, and there are a number of different access paths which can be used for tables and indexes. This course explores the access paths used for tables, such as full table, rowid, and sample table scan. It also examines the access paths used for indexes, such as unique, range, full, fast full, skip, and index join index scans, as well as bitmap indexes and combining bitmap indexes. Additionally, this course discusses B*-tree, bitmap, composite, and invisible indexes and nullable columns when using indexes. Bitmap operations, guidelines for managing indexes, index usage, clusters, sorting operators, join methods, and other n-array operations are also covered.
