通过验证复制中的所有参与方都具有与主控复制定义匹配的表和复制的列属性，确保数据完整性。
Ensures data integrity by verifying that all participants in the replicate have table and replicated column attributes that match the master replicate definition.
除了这些表，我们使用一个视图(图5)简化了获取一个完整服务定义的数据库访问。
In addition to these tables, we are using a view (Figure 5), allowing us to simplify database access for getting a complete service definition.
我们还要实现另外一些任务：让这个表包含完整的结构定义；还要确保这个数组前面没有空项，这样就不会浪费空间。
A little extra work would also allow tables containing full struct definitions; a little more would ensure that space isn't wasted at the front of the array with useless empty entries.
对于第二个策略(每个类层次结构一个表)，您必须用检测约束定义您自己的完整性。
For our second strategy (one table per class hierarchy), you'll have to define your integrity using check constraints.
附录中显示了这些表的完整定义。
The complete definition of these tables is shown in the WIP_HistoryTableDefinitions.txt file contained in the DWC_WIP.zip download.
检验复制的所有参与者是否具有与主复制定义相匹配的表，以及被复制列的属性，确保数据完整性。
Ensure data integrity by verifying that all participants in the replicate have table and replicated column attributes that match the master replicate definition.
在使用完整的自定义(在HATS项目中定义)顺序表之前，HATS先使用这个屏幕顺序表来检查匹配项。
HATS USES this ordered list of screens to check for matches before using the entire list of ordered customizations defined in the HATS project.
例如，当MQT中的两个或多个表定义了引用完整性关系并且联结谓词在它们自己的主键-外键列上时，就会出现这种情况。
For example, this might happen when two ore more of the tables in the MQT have a referential integrity relationship defined and the join predicate is on their primary key - foreign key columns.
嵌套表的定义不完整。
外键约束允许您定义父表和子表之间的引用完整性。
A Foreign key constraint allows you to define referential integrity between a parent and child table.
外键约束允许您定义父表和子表之间的引用完整性。
A Foreign key constraint allows you to define referential integrity between a parent and child table.
