Transactions are fundamental units of work in any database system. They represent a series of operations that are executed as a single, indivisible unit. The concept of a transaction ensures that either all the operations within it are executed successfully, or none at all, preserving the integrity of the system. In a transactional context, we focus on the Atomicity, Consistency, Isolation, and Durability (ACID) properties, which govern the behavior of these operations.ACID properties serve as the backbone of robust data management systems. They are crucial in ensuring that transactional operations are reliable and consistent, even in the presence of multiple concurrent operations or system failures. Without ACID guarantees, data systems could become unreliable, leading to data corruption, inconsistencies, and operational inefficiencies.
To understand the foundation of transactional systems, let's break...
