SQL Transactions

SQL Transactions A deep-dive walkthrough of database transactions — covering the ACID properties as precise, individually meaningful guarantees, BEGIN/COMMIT/ROLLBACK mechanics and savepoints, isolation levels and the specific concurrency anomalies (dirty reads, non-repeatable reads, phantom reads) each one prevents or permits, locking and how it underlies isolation, deadlocks and how to reduce them, the write-ahead transaction log as the mechanism behind durability, the real costs of long-running transactions, and how all of this maps onto EF Core's SaveChanges and explicit transaction APIs.
