Why need to drop the DB to see the changes made inside views?

I have changed some value/label in view then I refresh or also restart the server but my page display still get the old data.

Do you have any tip to make it fast reload or any relevant solution and see the change during the development mode?

If I want to see some changes were made then I need to drop database and run it again, it is very inconvenience? any solutions by not dropping database to see the change made?

Hello,

If the development was done in the sources and then the application was compiled and deployed, it is then necessary to reload the views to see the changes.
