ACID, refers to the four characteristics of a transaction in a database management system (DBMS): atomicity (atomicity), consistency (consistency), isolation (isolation, also known as independence), persistence (durability). In a database system, a transaction refers to a complete logical process consisting of a series of database operations. For example, bank transfer, deduction of the amount from the orig

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

Spring provides flexible and convenient transaction management capabilities, but these functions are based on the transaction mechanism of the underlying database itself. To gain insight into the transaction management and configuration of spring, it is necessary to learn the basics of database transactions first.What is a database

There are three types of Java transactions: JDBC Transactions, JTA (Java Transaction API) transactions, container transactions. Common container transactions such as spring transactions, container transactions are mainly provided by the Java Application Server, container transactions are mostly based on JTA completion, which is a jndi based, rather complex API implementation. So this article does not discuss container transactions. This article mainly

About MySQL transaction isolation level and MySQL transaction isolation level This article elaborates four concepts related to databases: transactions, database read phenomena, isolation levels, and lock mechanisms. I. Transactions Let's take a look at Baidu encyclopedia's definition of database transactions: Perform a series of operations as a single logical unit, either completely or completely.

There are four database isolation levels, as described in the high-performance mysql book: Then let's talk about how to modify the transaction isolation level: 1. Modify the global settings, modify the mysql. ini configuration file, and add Copy codeThe Code is as follows:# Optional parameters include: READ-UNCOMMITTED, READ-COMMITTED, REPEATABLE-READ, SERIALIZABLE.[Mysqld]Transaction-isolation = REPEATA

I. Overview of transactions This section is purely for writing and writing, right when the knowledge of the database and familiar with how to write a blog, who let their dishes. ：） Read a lot of other blogs and materials, business two words are fast not to know, then actually the concept of business is very simple, can be understood as one thing, in the computer, it is a sequence of operations. It differs from ordinary things in that it must obey the acid principle specified by ISO/IEC.

I. Understanding of isolation Levels1. Dirty ReadingFirst, it is understood that a transaction has changed the data, although the transaction has not yet been committed, but at this point the data found by the other statements is changed after the transaction.
