Before you can create a database or user, you must have sufficient privileges granted to you.
To create a database, use the CREATE DATABASE statement. You can specify the name of the database, the amount of storage to allocate, and other attributes.
To create a user, use the CREATE USER statement. The statement authorizes a new user identification (user name) for the database and specifies a password for user authentication. Because the system creates a database for each user, the CREATE USER statement is very similar to the CREATE DATABASE statement.
