Detailed explanation-1: -Advanced Compression includes Advanced LOB Compression and Deduplication features that can dramatically reduce the storage footprint of SecureFiles data, while also improving performance. It is extremely common for applications to store exact replicas of files.
Detailed explanation-2: -A common data compression technique removes and replaces repetitive data elements and symbols to reduce the data size. Data compression for graphical data can be lossless compression or lossy compression, where the former saves all replaces but save all repetitive data and the latter deletes all repetitive data.
Detailed explanation-3: -Lossy compression reduces a file by permanently eliminating certain information, especially redundant information. When the file is uncompressed, some of the original information is not there, although the user may not notice it.
