然而，有时候可能需要根据外部事件或者从一个非ibm环境中使用自己的调度程序触发规则执行。

However, in some cases it may be necessary to trigger the execution of rules based on external events, or from a non-IBM environment using its own scheduler.

如果您想要使用触发器、聚合函数、外部联接、视图以及其他SQL功能，HSQLB都可以满足您的需要(大部分轻量级关系数据库无法做到这一点)。

If you want triggers, aggregated functions, outer joins, views, and other SQL features, they are all there (something you won't get from most lightweight relational databases).

最后，当资产的外部状态达到一个预定义传输点时，您可以在Asset Manager中使用一个外部触发器来传输一个资产状态。

Finally, you can use an external trigger to transit the states of an asset in asset Manager when the asset's external state reaches a pre-defined transition point.
