Oracle Advanced Compression

Advanced Compression, an option introduced in Oracle Database 11g Enterprise Edition, offers a comprehensive set of compression capabilities to help organizations reduce costs, while maintaining or improving performance. It significantly reduces the storage footprint of databases through compression of structured data (numbers, characters) as well as unstructured data (documents, spreadsheets, XML and other files). It provides enhanced compression for database backups and also includes network compression capabilities for faster synchronization of standby databases. It now includes Total Recall for storing and auditing of historical data.
