Let's explore basic aggregation and composition aggregation further.
让我们更进一步探讨基本聚合和组合聚合。
So I have some question about the association, aggregation and composition in UML diagram.
所以我有一些问题关于关联、聚合和组成在UML图。
Aggregation and composition relationships generally represent "has a" relationships, where one class is subordinate to another.
聚合和复合关系通常表示“拥有”关系，其中一个类隶属于另一个类。
For e. g. though association, aggregation and composition are different types of relationships, all THREE have distinct notations to show them.
例如，虽然关联，聚合和组成不同类型的关系，这三个国家都向他们展示不同的符号。
With aggregation and composition, anything you do to the whole in the database you almost always need to do to the parts, whereas with association that is not the case.
对于聚合和组合，在数据库中对整体所做的操作通常需要同时对部分进行操作，而关联就不是这样。
The difference between aggregation and composition is that objects owned as composites can't be created without their owner, so usually they are created by their owner.
聚合和组合的区别是，拥有作为复合材料不能创建对象没有主人，所以通常是由他们的所有者。
There are four types of relationships that an object can be involved with: inheritance, association, aggregation, and composition.
对象之间有四种类型的关系：继承、关联、聚合和组成。
Mapping associations, aggregation, and composition.
映射关联、聚合和组成。
The Aggregation property is important for complex types: it has to be set to Composition for attributes of a class type and Shared for attributes of metaclass or stereotype.
聚合属性对于复合属性集非常重要：它必须要为类的属性设置成Composition并且为元类的原型类型设置为 Shared 。
Service composition is highly complex and often includes transactions, unit-of-work boundaries, error handling, security and propagation of credentials, and aggregation of business logic.
服务合成(service composition)是相当复杂的，而且常常涉及到事务、工作单元边界、错误处理、安全性与证书分发、以及业务逻辑聚合等方面的问题。
These include one-to-one and one-to-many composition associations and many-to-one and many-to-many aggregation associations.
这些包括一对一和一对多构成关联，以及多对一和多对多的聚合关联。
The composition model allows discovery of services having the desired interfaces and infrastructure (QoS) policies and their aggregation into new services, modules, and solutions.
使用组合模型，可以发现具有所需的接口和所需的基础设施(QoS)策略的服务，并且将这些服务聚合到新的服务、模块和解决方案中。
