我认为第一个。隐藏查询的复杂性。它非常适合于视图。当我们规范化数据库表时如何增加。现在，当表数量增加时，获取数据是非常困难的。所以最好的处理方法是遵循视图。如果我错了，请纠正我。

这并没有确切地回答你的问题，但我认为值得一提的是物化视图。我的经验主要是使用Oracle，但是SQL-Server应该是相当相似的。

We used something similar in our architecture to address XML performance problems. Our systems are designed with a lot of data stored as XML on a row and applications might need to query particular values within it. Handling lots of XMLTypes and running XPaths across large number of rows has a large impact on performance so we use a form of materialized views to extract the desired XML nodes out into a relational table anytime the base table changes. This effectively provides a physical snapshot of the query at a point in time as opposed to standard views which would run their query on demand.

当我想要查看一个表的快照和/或视图(以只读方式)时

下面是如何使用视图以及权限来限制用户可以在表中更新的列。

/* This creates the view, limiting user to only 2 columns from MyTestTable */
CREATE VIEW dbo.myTESTview 
WITH SCHEMABINDING AS
SELECT ID, Quantity FROM dbo.MyTestTable;

/* This uses the view to execute an update on the table MyTestTable */
UPDATE dbo.myTESTview
SET Quantity = 7
WHERE ID = 1

我们创建view来限制或严格访问表中的所有行/列。如果所有者希望只有特定或有限的行/列需要共享，那么他将使用这些列创建一个视图。
