Theories of concurrency

Theories of concurrency explore how multiple processes or actions happen at the same time in systems like databases or computer programs. They aim to ensure these actions occur efficiently without conflicts, such as data corruption or errors. Key ideas include managing access to shared resources, maintaining data consistency, and ensuring transactions are completed correctly even when done simultaneously. Techniques like locking, timestamps, and protocols help coordinate concurrent operations, balancing speed and accuracy. Overall, these theories provide the foundation for designing reliable systems that handle many processes happening simultaneously.
