Description: Transaction synchronization is a mechanism that allows actions to be performed before or after a transaction is confirmed. This concept is crucial for ensuring data integrity and consistency in applications that handle multiple database operations. Transaction synchronization ensures that all operations within a transaction are successfully completed before being committed, or that, in case of an error, all actions taken are rolled back, thus maintaining the original state of the database. This approach is fundamental in systems where accuracy and reliability are essential, such as in financial or e-commerce applications. Transaction synchronization frameworks provide tools and annotations, such as @Transactional in some programming environments, that facilitate the implementation of transaction synchronization. This allows developers to focus on business logic without worrying about transaction management details, resulting in cleaner and more maintainable code. Transaction synchronization not only enhances application robustness but also optimizes performance by grouping related operations, thereby reducing the load on the database and improving user experience.
