They can be used to provide row- or column-level access to data, to wrap up complex joins, to perform complex aggregate queries, and to otherwise customize the display of data. In this chapter, learn how to define, create, and modify views, and how to perform index analysis and optimize performance in SQL Server. The biggest problem is that just when you get used to accepting a limitation, Microsoft comes up with an amazing, new feature that overcomes it!
