A client application can call on the stored procedure to perform a series of native operations in one trip to the database, rather than involving multiple trips to the database server.

客户端应用程序通过调用存储过程只需要访问数据库一次就可以执行一系列本地操作，而不用多次访问数据库服务器。

youdao

For example, an update of an employee object that requires updating several database tables that make up the object could be done in a single trip to the database rather than multiple trips.

例如，要更新雇员对象，就需要更新组成该对象的若干数据库表，这可在一个(而非多个)数据库往返行程中完成。

youdao

Like the traversal container session, a vulnerability probe session might contain multiple containers, each of which consists of only one request-response pair needed to complete a round trip.

与传送容器会话相似，漏洞探测会话可以包含多个容器，其中每一个容器仅由一对完成往返过程的请求响应组成。

youdao

Second, many use multiple sites to purchase different elements of their trip.
