【数据架构】TOGAF建模:数据迁移图
数据迁移图的目的是显示从源应用程序到目标应用程序的数据流。该图将提供源/目标分布的可视化表示,并作为数据审核和建立可追溯性的工具。该图可以根据需要进行细化或增强。例如,该图可以只包含迁移环境的总体布局,也可以包含单个应用程序元数据元素的详细信息。
可以在概念级或物理级表达迁移。应用程序通信图也可以用来表示数据迁移。“迁移”依赖关系是正式化迁移的关键元素。
UML/BPMN EAP Profile

 Business Entity: Describes the semantics of the entities in the business, independently of any IS consideration (e.g. storage, technology, etc).

 Business Entity (developed form): This also presents here one attribute, in other words, one property that the entity may have.

 Migrates link: Migration of elements between two versions of the IS. Generally used between business entities or application components.

迁移依赖项可以在业务实体之间进行,也可以在“属性”级别更精确地定义。
在这个例子中,我们看到前一个数据模型中的几个属性在新的数据模型中被提升为“实体”。
这些图很快就会被链接弄得乱七八糟,它们应该集中在源或目标业务实体上。表格也可在下表中使用:
| Origin | Migrates in | ||
| Element | Nature | Element | Nature | 
| transportation | Class | Travel | Class | 
| Hotel | Class | ||
| Flight | Class | ||
| Travel | Class | Travel | Class | 
| Travel.destination | Attribute | Destination | Class | 
| Travel.hotel | Attribute | Hotel | Class | 
| Reservation | Class | Roomreservation | Class | 
| Hotem | Class | ||
我们看到,新模型的结构更好了,因为它对以前分散的信息进行了分组。它是标准化的。
