Data migration scoping 数据迁移范围界定
This module-level scoping provides a degree of abstraction (data hiding) that lets you restrict visibility of the database to a specific module.
此模块级范围提供了一个抽象级别(数据隐藏)，允许您限制数据库对特定模块的可见性。
Such segregation is important in a project context such as an SOA effort as it allows scoping down to the data sources that are important for analysis.
在诸如 SOA 之类的项目上下文中，这样的分离是很重要的，因为它允许将分析的范围缩小到对分析比较重要的数据源上。
As part of the scoping, the analyst may determine that additional review of how data can be aligned and harmonized (particularly in a composite or complex service) is required.
作为范围界定的一部分，该分析可能确定需要进行额外的检查，检查如何校准和协调数据(尤其是在复合或复杂的服务中)。
