Database Management Systems: Chapter 1 - Disk Storage, Basic File Structures, and Hashing includes Disk Storage Devices, Files of Records, Operations on Files, Unordered Files, Ordered Files, Hashed Files, RAID Technology. | Chapter 1 Disk Storage, Basic File Structures, and Hashing. Adapted from the slides of “Fundamentals of Database Systems” (Elmasri et al., 2003) Chapter Outline Disk Storage Devices Files of Records Operations on Files Unordered Files Ordered Files Hashed Files Dynamic and Extendible Hashing Techniques RAID Technology Disk Storage Devices Preferred secondary storage device for high storage capacity and low cost. Data stored as magnetized areas on magnetic disk surfaces. A disk pack contains several magnetic disks connected to a rotating spindle. Disks are divided into concentric circular tracks on each disk surface . Track capacities vary typically from 4 to 50 Kbytes. Disk Storage Devices (cont.) Because a track usually contains a large amount of information, it is divided into smaller blocks or sectors . The division of a track into sectors is hard-coded on the disk surface and cannot be changed. One type of sector organization calls a portion of a track that subtends a .
