One Spring transaction is widely used by transactions. One transaction method should not call another transaction method. Otherwise, two transactions will be generated. As a result, developers are tied up when designing transaction methods for fear of stepping on the mines accidentally.In fact, this is a misunderstandi

, and the state change must also be undone. This may involve invoking the service again and performing another reversal of the effect of the action. Solution SolutionsImplement a compensating transaction. The steps in a compensating transaction must undo the effects of the steps in the original operation. A compensating transaction might not being able to simply

Four features of database transactions, transaction isolation level, and transaction isolation level This article describes the four major features of transactions in the database (ACID), and details the isolation level of transactions. If a database claims to support transaction operations, the database must have the following four features:(1) Atomicity) Atomic

Database transaction isolation mechanism and transaction isolation mechanism Transaction isolation level: the degree of isolation between one transaction's modification to the database and another transaction in parallel. When two concurrent transactions access the same row in the database table at the same time, these

Common errors to be aware of when implementing transactions on the Java platform Transactions are often used in applications to maintain high data integrity and consistency. If you do not care about data quality, you do not need to use transactions. After all, transaction support on the Java platform reduces performance, causes locking and database concurrency problems, and increases application complexity.About this series Transactions improve data q

Label:A transaction executes a sequence of operations as a unit, either succeeds or fails, and rolls back to its original state. In transactional terminology, a transaction is either committed or aborted. To commit a transaction, all participants must ensure that any changes to the data are permanent. Regardless of the system crash or other unforeseen events, the

I. ACID properties of database transactions Atomicity (Atomic) (Atomicity) A transaction must be an atomic unit of work. modifications to its data must either be performed in all or not. Generally, operations associated with a transaction share a common goal and are mutually dependent. If the system executes only one subset of these operations, the overall goal of the
