For example, if the mapping attribute of the DataSource object is not set, the data source might not act as the data source in the container-managed persistence (CMP).
例如，如果未设置DataSource对象的mapping属性，则数据源的行为方式不会与容器管理的持久性(CMP)中的数据源相同。
It appeared to us that a managed persistence solution was not required for our programming model, and we wanted to unleash the power of SQL without hiding it from the developer.
显然，对于我们的编程模型，受管持久性解决方案不是必需的，我们希望释放出SQL的威力，而不是对开发人员隐藏它。
However, this choice can be limited by the deployment tool's limitation to map the bean instance's state to the database, in which case a bean-managed persistence (BMP) entity bean may be used.
但是，这个选择会受到部署工具局限性的限制—部署工具将bean实例的状态映射到数据库，这种情况下可能会使用bean管理的持久性(BMP)实体bean。
Compared with flow-managed persistence in atomic flows, the most significant change happens to the scope of transactions: atomicity applies to each step of the process rather than the entire flow.
与原子流中流管理的持久化相比，事务作用域发生的最大变化时：原子性应用于进程的每一步而不是整个流。
