PHP UK Conference 2014 - Morgan Tocker - Locking And Concurrency Control

This talk covers the essential features of relational database management systems (RDBMS) that protect data integrity and prevent concurrent data modifications. The speaker discusses key concepts such as table and row locks, multi-version concurrency control (MVCC), deadlocks and lock waits, as well as transactions and isolation levels. Attendees gain insights into common database errors and how applications should effectively handle them. While examples are drawn from MySQL 5.6, the principles discussed are widely applicable across various database systems.
