System R* Project Commences

Building on the success of System R, IBM researchers began work on System R*, explicitly tackling the challenges of distributed relational databases, focusing on transparent data distribution and transaction management.

Significance

System R* was one of the first comprehensive attempts to build a fully functional distributed relational database system, demonstrating key concepts like distributed query optimization and the two-phase commit protocol. Its papers became foundational texts for the field.
