What are SQL views used for?
Views are virtual tables that can be a great way to optimize your database experience. Not only are views good for defining a table without using extra storage, but they also accelerate data analysis and can provide your data extra security.
What is the benefit of views in SQL Server?
Views can provide advantages over tables: Views can represent a subset of the data contained in a table. Consequently, a view can limit the degree of exposure of the underlying tables to the outer world: a given user may have permission to query the view, while denied access to the rest of the base table.
What is the difference between tables and views?
A table is structured with columns and rows, while a view is a virtual table extracted from a database. The table is an independent data object while views are usually depending on the table. The table is an actual or real table that exists in physical locations.
What are different types of views in SQL Server?
There are three types of System defined views, Information Schema, Catalog View, and Dynamic Management View.
