The document discusses how to create and delete databases in Oracle. It describes two methods to create a database: using the Database Configuration Assistant (DBCA) or using SQL commands. The DBCA method involves stepping through a wizard that prompts for database details like name, storage, and credentials. It also describes testing a connection to the new database and verifying it contains sample tables. For deleting a database, it similarly outlines using either the DBCA or a SQL DROP DATABASE command.
