The document discusses partitioning in Oracle data warehouses. It covers key concepts like different partitioning methods, benefits of partitioning like partition pruning and partition-wise joins, and choosing the right partition key. It also discusses handling large dimension tables using hash or list partitioning and automating partition maintenance using features in Oracle 11g like interval partitioning and incremental global statistics. The overall message is that partitioning is a powerful Oracle feature for data warehouses but implementing it effectively can be complex.
