Oracle Release 11.2 offers Advanced Compression, a way to reduce the overall size of your data by compressing commonly occurring values and strings with tokens, mnemonics that can represent much larger strings and values. Two types of compression are offered on systems not using Exadata-type storage: Basic and OLTP. Basic compression is available without the Advanced Compression licensing. A third compression option, Hybrid Columnar Compression (HCC), is available on Exadata systems and non-Exadata systems using Exadata-type storage. This is offered in two basic levels: QUERY and ARCHIVE.
