In this protocol, each site manages locks independently while coordinating with other sites to maintain consistency across the distributed system. ==Key Concepts== *'''Global Serializability:''' Ensures that the execution of distributed transactions is equivalent to a serial execution. *'''Distributed Lock Manageme..." 최신 태그: 시각 편집

Transactions must obtain locks from the primary copy of the data item to ensure consistency and serializability across the system. ==Key Concepts== *'''Primary Copy:''' A specific node in the distributed system is designated as the authoritative source for managing locks for a particula..." 최신 태그: 시각 편집

In this approach, one node is designated as the primary site for each data item, and it coordinates the locking and transaction processing to ensure serializability across the system. ==Key Concepts== *'''Primary Site:''' A designated node that manages all lock requests for a specific data item. *'''Global Serializability:''' Ensures that all transacti..." 최신 태그: 시각 편집

Each site can operate independently while participating in a unified database system through communication over a network. ==Key Concepts== *'''Data Distribution:''' Data is distributed across multiple sites based on factors like performance, reliability, and locality. *'''Transparency:''' Users interact with the distributed d..." 최신 태그: 시각 편집

It involves decomposing a high-level query into sub-queries that are executed on different nodes, combining the results, and presenting a unified output to the user. ==Key Concepts== *'''Distributed Database:''' A collection of interconnected databases located on different physical sites. *'''Query Decomposition:''' Breaki..." 최신 태그: 시각 편집
