Since the emergence of commercial applications decades ago, databases have become a major component of software applications. Just as database management systems are critical, they also become very large and occupy a considerable amount of system resources, increasing management complexity. As software applications gradually modularize modules, a new type of database is more suitable than a large and comple

When it comes to business, it must refer to acid, the atomicity, consistency, isolation and permanence of the transaction. For a database, the ACID properties of transactions under normal and exceptional conditions are usually ensured through concurrency control and fault recovery methods. SQLite is no exception, although simple, still has its own concurrency control and recovery mechanism.
