InnoDB

InnoDB is a storage engine used in MySQL databases that manages how data is stored, retrieved, and maintained. It ensures data integrity, supports transactions for reliable operations, and handles multiple users accessing data simultaneously without conflicts. InnoDB uses techniques like row-level locking for performance and crash recovery to prevent data loss. Think of it as the engine that keeps a database organized, reliable, and efficient, enabling businesses to process and store large amounts of information securely and swiftly.
