还有一些系统参与者，它们是与您的系统进行交互的外部系统，在数据仓库项目的例子中，将是您要从中提取数据的遗留数据源。
There are also system actors, external systems that your system interacts with, which in the case of data warehouse projects, would be the legacy data sources that you extract data from.
第二种选择，如果数据源是遗留系统，可能就必须使用适配器或JCA。
Second, if the data sources are legacy systems, you might have to use adapters or JCA.
尽管数据整合模式无法单独处理应用程序迁移，但它是一个非常重要的组件，可以将数据从遗留系统移动到未来的平台。
Although the data consolidation pattern cannot solely address application migration, it is an important component in that it can move the data from the legacy system to the future platform.
