Understanding Database Transactions and Concurrency Management: Key Concepts for Data Integrity
In the world of modern databases, ensuring data accuracy and consistency while managing multiple users and transactions is crucial. My latest blog delves into the core concepts of database transactions, ACID properties, and concurrency control mechanisms, highlighting how these elements come together to maintain data integrity even under heavy load and concurrent access.
I explore the four ACID properties—Atomicity, Consistency, Isolation, and Durability—that form the backbone of reliable transaction processing, as well as serialisability and locking mechanisms that prevent issues like deadlocks, lost updates, and dirty reads. Additionally, I cover alternative concurrency techniques like optimistic concurrency control (OCC), and discuss when and how deadlocks occur, alongside methods to prevent or recover from them.
