METHOD OF STORING FILE DATA ON DISK

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently storing a file data on the disk storage in a data processing system. SOLUTION: The file data is stored in a number of different representations on disk. The file data is stored in streams which may assume any of several different representations on the disk. Each stream has an associated stream descriptor which describes how the stream is stored on the disk. The representations include storage of a stream in a single extent, storage of a stream in many extents and storage of a stream in an associated stream descriptor. COPYRIGHT: (C)2006,JPO&NCIPI
