If the view is a simple select of a table, then there would not be any benefits. But if it's a join of multiple tables, then we have significant benefits. You can also use Views to restrict the columns of a table or records of a table by adding a filter condition. In these cases you get better access control.

Below are few of the benefits:

  1. Simplify Access: Databricks Views can simplify access to data by providing a simplified view of a more complex dataset. This can make it easier to work with tables without having to remember all the complex joins and transformations. You can simply refer to the view in your code.

  2. Query Optimization: Databricks Views have query optimization built in, which means that the queries executed on the view may run faster than on the original table. This is because the system can optimize the query execution plan based on the view definition.

  3. Security: Databricks Views can be used to control access to data. You can grant access to the view and not the underlying tables. This can be particularly useful when you want to limit the amount of data that users can see or manage sensitive data.
