Database Transactions

A database transaction is a sequence of operations performed as a single unit of work. Think of it like a bank transaction: when you transfer money, the process should either complete fully or not at all, ensuring your balance is updated correctly. If anything goes wrong during the transaction—like a network issue or an error—the entire operation is rolled back, leaving everything as it was. This ensures data integrity and consistency. Transactions follow a set of rules called ACID: Atomicity, Consistency, Isolation, and Durability, which help maintain reliable database operations.
