Computer Science

Database

  • Collection of data stored to a computer
  • Data is organized in records
  • Fundamental features of databases:
    • Must be persistent
    • Can be shared
    • Must be kept accurate
    • Can be very large
    • Must be usable

Types

Replication

  • Duplicating data from one database server to others
  • Use cases
    • Increase redundancy of your system and tolerate regional failures
    • Move data closer to clients
      • Decreases latency for accessing data
