这个单位已附属于一个大的部门,不再作为一个实体独立存在。
The unit has become part of a larger department and no longer exists as a separate entity.
一个单位可包含多个部门。
或者,我们也可以决定将多个部门组合到一个XML文档中,例如,将属于同一个单位的部门放入一个XML文档中(粗粒度)。
Alternatively, we could have decided to combine multiple or many departments into a single XML document, e.g. all those that belong to one unit (coarse granularity).
