A savepoint is a mechanism within a database transaction that allows a user to set a point to which they can later roll back, providing more granular control over transaction management. This feature is particularly useful in complex transactions, enabling partial rollback without affecting the entire transaction, thus enhancing error recovery and data integrity.

Transaction management is a critical component in database systems that ensures transactions are processed reliably and ensures data integrity despite system failures. It encompasses a set of techniques to control concurrent access, maintain consistency, and ensure atomicity, isolation, and durability of transactions.

Error recovery is a critical process in computing and communication systems that involves detecting, diagnosing, and correcting errors to ensure system reliability and data integrity. Effective error recovery mechanisms can minimize downtime and prevent data loss, enhancing overall system performance and user experience.

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle, ensuring that it remains unaltered and trustworthy for decision-making and analysis. It is crucial for maintaining the credibility of databases and information systems, and involves various practices and technologies to prevent unauthorized access or corruption.
