【问题描述】:
我对@987654323@ 和data integrity 有点困惑。来自Oracle Database Concepts:
data integrity
--------------
Business rules that dictate the standards for acceptable data. These rules
are applied to a database by using integrity constraints and triggers to
prevent invalid data entry.
Consistency
-----------
Consistency states that only valid data will be written to the database.
那么data consistency 和data integrity 有什么区别?
提前致谢。
