In fact, the deepest reason for all deadlocks is: resource competition performance 1:A user a accesses Table A (locking table A) and then accesses Table BAnother user B accesses table B (Table B is locked) and then attempts to access TableAt this time, user a has locked table B because user B has to wait for user B to release table B to continue. Well, the old man will have to wait honestly.Similarly, user B has to wait for user a to release Table A to continue.Solution:This deadlock is caused b

Label:Originally intended to write about the transaction control process in the SSIS package, it was found that many of the basic concepts needed to be based on the isolation level of SQL Server transactions and transactions. So it took some time to get a good look at the concepts of transactions in SQL Server database, the ACID principle, the common problems in transactions, the causes of problems, and the level of

Concurrent transaction processing and concurrent Transaction Processing Transaction protection is a must for the software industry. Many financial companies simply fail to handle transactions. As we all know, transactions have four major features: ACID. That is, atomicity, consistency, isolation, and durability. Four features Atomicity A

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

The principle and application of Java transaction in-depth Java transactionFirst, what is a Java transactionThe general idea is that transactions are only relevant to the database.Transactions must be subject to the ACID principles established by ISO/IEC. Acid is an abbreviation for atomicity (atomicity), consistency (consistency), isolation (isolation), and persistence (durability). The atomicity of a transaction
