Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Database views are created using the CREATE VIEW statement. "

A block of code is set as follows:

import java.sql.Connection;

Any command-line input or output is written as follows:
