Synchronization (computer Science) - Data Synchronization

A distinctly different (but related) concept is that of data synchronization. This refers to the need to keep multiple copies of a set of data coherent with one another.

Examples include:

  • File synchronization, such as syncing a hand-held MP3 player to a desktop computer.
  • Cluster file systems, which are file systems that maintain data or indexes in a coherent fashion across a whole computing cluster.
  • Cache coherency, maintaining multiple copies of data in sync across multiple caches.
  • RAID, where data is written in a redundant fashion across multiple disks, so that the loss of any one disk does not lead to a loss of data.
  • Database replication, where copies of data on a database are kept in sync, despite possible large geographical separation.
  • Journaling, a technique used by many modern file systems to make sure that file metadata are updated on a disk in a coherent, consistent manner.

Famous quotes containing the word data:

    Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.
