Description: Durability in the context of database systems refers to the ability of a system to maintain data integrity despite failures. This means that even in adverse situations, such as hardware failures, power outages, or software errors, the stored data must remain intact and accessible. Durability is achieved through mechanisms like data replication, where multiple copies of information are stored across different nodes within a cluster. This not only protects against data loss but also ensures that the system can quickly recover from failures. In distributed systems, durability is fundamental as it allows data to be consistent and available at all times, which is crucial for applications requiring high availability and performance. Durability is often measured in terms of the system’s ability to recover data after a failure, and it is a critical aspect in the design of modern database architectures, where data loss can have significant consequences for businesses and end-users.
