Study Notes
Storage Hierarchy
- Databases are typically stored on magnetic disks
- Storage hierarchy consists of:
- Primary storage: CPU main memory and cache memory
- Secondary storage: magnetic disks, flash memory, and solid-state drives
- Tertiary storage: removable media
Memory Hierarchies and Storage Devices
- Cache memory uses static RAM
- DRAM (Dynamic Random Access Memory) is used for main memory
- Mass storage devices include:
- Magnetic disks
- CD-ROM, DVD, and tape drives
- Flash memory, which is nonvolatile
Storage Types and Characteristics
- Storage types can be characterized by:
- Capacity
- Access time
- Max bandwidth (transfer speed)
- Commodity cost
