If you don't make this assumption, you need to introduce nested transactions at the language level.
如果不做这样的假设，你需要在语言层面上引入内嵌的事务。
There are many Active Record updates in this release including the introduction of nested transactions.
该发布中有很多ActiveRecord更新，包括嵌套事务的引入。
Note that the same TCS can be used by nested transactions, ensuring that if the nested transaction fails, the parent transaction will also fail.
注意到嵌套的事务可以使用同一个TCS，确保如果嵌套事务失败了，那么父事务也将失败。
An arbitrary number of nested TransactionScopes are possible, and internally the System.Transaction namespace maintains the stack of all of the ambient transactions.
可以嵌套任意数量的TransactionScope，在内部，System .Transaction命名空间保留所有环境事务的堆栈。
The transaction coordination diagram is used to show the constituents of a defined transaction, the order of processing (sequential vs. parallel), and nested transactions.
事务协调图用来显示确定的事务的构成、处理顺序（顺序的vs.并行的），及嵌套的事务。
In real business life, there are more details and options and we might have nested business processes or even coordinated transactions within other coordinated transactions.
在真实的业务中，还有更多的细节和选择，我们可能嵌套业务流程，甚至在其它协调的事务中嵌套协调的事务。
The aim of the current SAP programming model is to replace long, nested screen sequences with single-screen transactions.

Moreover, conventional concurrency control and scheduling methods for update transactions are not suitable in that mobile real-time transactions are complicated and nested.
而且，由于移动实时数据库系统中大多数事务都是复杂的嵌套事务，传统调度策略都已不太适用。
