The document discusses the ACID properties that transactions should possess: 1. Atomicity - Transactions are atomic units that are fully completed or not completed at all. 2. Consistency - Transactions preserve consistency by ensuring the database only transitions between valid states. 3. Isolation - The execution of one transaction is isolated and not interfered with by other concurrent transactions. 4. Durability - Committed transaction changes persist in the database and survive failures through logging and recovery.
