Distributed databases: How can consistency be maintained in replicated systems? This paper delves into the concurrency control strategy employed by SDD-1, a System for Distributed Databases, designed to guarantee database consistency in the face of data distribution and replication across multiple sites. SDD-1 addresses the challenges posed by data replication by implementing a sophisticated concurrency control mechanism. This approach ensures that even with portions of data replicated throughout a network, the database remains consistent. The authors detail the specific algorithms and protocols used within SDD-1 to manage concurrent access to data and prevent conflicts. As part of a series of companion papers on SDD-1, this research contributes to the understanding and development of distributed database systems. By tackling the complexities of concurrency control, SDD-1 paves the way for more reliable and efficient distributed data management solutions, crucial for modern applications relying on decentralized data.
