Even the most powerful computers have finite processing and storage – eventually a database will exceed those limits. Thus, a distributed database is designed to spread the processing and storage of data across multiple machines. Such distribution introduces challenges for availability, concurrency, and joins when processing queries.

Learning Objectives

  • Compare and contrast centralized and distributed databases
  • Describe the techniques used by a distributed database management system (DBMS) for joins
