This lecture covers the Decomposition Storage Model (DSM) focusing on column-oriented storage. It explains the advantages of DSM, such as memory efficiency and faster queries. The lecture delves into columnar storage examples, bit-vector encoding, dictionary encoding, and compression techniques like run-length encoding. It also discusses write-optimized storage, per-page dictionaries, and operators over compressed data.
