What are database cursors? when might you use them?

A database cursor is a mechanism used to traverse through a set of data retrieved from a database. Cursors are commonly used in programming languages to execute queries that retrieve a large number of rows. Cursors allow for more control over the processing of data and can be used to perform tasks such as updating or deleting records. However, cursors can be resource-intensive and slow down performance, so they should only be used when necessary.

What is the difference between a view and a materialized view?

A view is a virtual table that is based on one or more tables, while a materialized view is a physical copy of a view that is stored on disk. Unlike views, materialized views can be indexed for faster access and can improve query performance in data-intensive environments.
