Distributed Databases

Distributed databases store and process data across multiple networked nodes to improve scalability, availability, or locality.

Architectural Styles

  • Homogeneous: Same DBMS at all nodes.
  • Heterogeneous: Different DBMS implementations across nodes.

Key Issues

  • Data fragmentation and replication
  • Distributed query processing
  • Transaction management and distributed commits
  • Network latency and partial failures

Distributed Transactions

Protocols like Two-Phase Commit (2PC) and Three-Phase Commit (3PC) coordinate commits across nodes, but add latency and complexity.
