Data management is concerned with the distribution of data to users and the protection of that data from loss such as fire, theft, or unauthorized access. Data management includes these areas:

  • Data protection    Protecting data from catastrophic events, theft, or similar problems using archiving, backup, and other techniques. See "Backup and Data Archiving" and "Data Protection."

  • Data availability    Making sure that data is available to users. See "Fault Tolerance and High Availability" and "Data Center Design."

  • Data migration    Similar to archiving, but provides a way for users to quickly access files that have been archived. See "Data Migration" and "Storage Management Systems."

  • Data warehousing    Data warehousing uses data summarization techniques to make large volumes of data available in a form that is easily accessible to data clients. See "Data Warehousing." A related topic is "SANs (Storage Area Networks)."

  • DBMS (database management system)    A database is a file that contains records with information in fields. A DBMS is a complete package that provides a query language and provides access to the data. See "DBMS (Database Management System)."

  • Distributed and replicated data    Distributed data is stored on multiple servers across a network. The data is usually in the form of a database that is automatically replicated (copied) to other locations where it is easily accessible by users at those locations. See "DBMS (Database Management System)," "Replication," and "Web Caching."

  • Redundancy    Redundancy methods are used to protect systems from failure, to protect data from loss and corruption, and to ensure that communication systems stay online and provide appropriate levels of service. See "Redundancy."

  • Security    User access rights, directory rights, and file rights all deal with restricting user access to specific files, directories, and servers. See "Security."
