+事务是指一个操作，包含一个或多个SQL语句，这些语句的执行要么完全成功，要么完全失败，是一个不可分割的工作单位。
+
+## 显式事务和隐式事务
+
+### 显式事务
+
+显式事务需要用户主动的开启，提交或回滚事务。 在 Doris 中，提供了 2 种显式事务：
+
+1. 本文中介绍的事务写方式，即
+
+```sql
+begin;
+[INSERT, UPDATE, DELETE statement]
+COMMIT; / ROLLBACK;
+```
+
+2. [Stream Load 2PC](load-atomicity.md#stream-load)
+
+### 隐式事务
+
+隐式事务是指用户在所执行的一条或多条SQL语句的前后，没有显式添加开启事务和提交事务的语句。
+
+在 Doris 中，除[Group
Commit](group-commit-manual.md)外，每个导入语句在开始执行时都会开启一个事务，并且在该语句执行完成之后，自动提交该事务；或执行失败后，自动回滚该事务。更多详细信息请参考:
[导入事务与原子性](load-atomicity.md)。
+
+## 事务操作
+
+### 开启事务
+
+```sql
+BEGIN;
+
+BEGIN WITH LABEL {user_label};
+```
+
+如果执行该语句时，当前 Session 正处于一个事务的中间过程，那么 Doris 会忽略该语句，也可以理解为事务是不能嵌套的。
+
+### 提交事务
+
+```sql
+COMMIT;
+```
+
+用于提交在当前事务中进行的所有修改。
+
+### 回滚事务
+
+```sql
+ROLLBACK;
+```
+
+用于撤销当前事务的所有修改。
+
+事务是 Session 级别的，如果 Session 中止或关闭，也会自动回滚该事务。
+
+## 事务写入
+
+目前 Doris 中支持 2 种方式的事务写入。
+
+### 单表多次`INSERT INTO VALUES`写入
+
+假如表的结构为：
+
+```sql
+CREATE TABLE `dt` (
+ `id` int(11) NOT NULL,
+ `name` varchar(50) NULL,
+ `score` int(11) NULL
+) ENGINE=OLAP
+UNIQUE KEY(`id`)
+DISTRIBUTED BY HASH(`id`) BUCKETS 1
+PROPERTIES (
+ "replication_num" = "1"
+);
+```
+
+写入：
+
+```sql
+mysql> BEGIN;
+Query OK, 0 rows affected (0.01 sec)
+{'label':'txn_insert_b55db21aad7451b-b5b6c339704920c5', 'status':'PREPARE',
'txnId':''}
+
+mysql> INSERT INTO dt (id, name, score) VALUES (1, "Emily", 25), (2,
"Benjamin", 35), (3, "Olivia", 28), (4, "Alexander", 60), (5, "Ava", 17);
+Query OK, 5 rows affected (0.08 sec)
+{'label':'txn_insert_b55db21aad7451b-b5b6c339704920c5', 'status':'PREPARE',
'txnId':'10013'}
+
+mysql> INSERT INTO dt VALUES (6, "William", 69), (7, "Sophia", 32), (8,
"James", 64), (9, "Emma", 37), (10, "Liam", 64);
+Query OK, 5 rows affected (0.00 sec)
+{'label':'txn_insert_b55db21aad7451b-b5b6c339704920c5', 'status':'PREPARE',
'txnId':'10013'}
+
+mysql> COMMIT;
+Query OK, 0 rows affected (1.02 sec)
+{'label':'txn_insert_b55db21aad7451b-b5b6c339704920c5', 'status':'VISIBLE',
'txnId':'10013'}
+```
+
+这种写入方式不仅可以实现写入的原子性，而且在 Doris 中，能提升 `INSERT INTO VALUES` 的写入性能。
