Description: TransactionDefinition is an interface in the context of the Spring framework that defines the properties of a transaction, including isolation level and propagation behavior. In simple terms, a transaction is a unit of work that is executed atomically, meaning it either completes in its entirety or does not occur at all. This is crucial in applications that require consistency and reliability, especially in systems handling critical data. The TransactionDefinition interface allows developers to specify how transactions should behave in different scenarios, such as whether they should be isolated from other transactions or whether they should propagate across different contexts. Defined properties include the isolation level, which determines how concurrent reads and writes are managed, and the propagation behavior, which indicates how nested transactions should be handled. This flexibility is essential for building robust and scalable applications, as it allows developers to tailor transaction management to the specific needs of their applications, thereby ensuring data integrity and the correct execution of operations.
