## Lesson 11: Tasks on completion of the tutorial

Congratulations! You have just completed the Oracle Discoverer Administrator tutorial. By now, you should have a solid understanding of the major features of Oracle Discoverer Administrator and how it affects every aspect of an end users view of database information through business areas.

You have learned that you can use Oracle Discoverer Administrator to help end users make much more effective use of database information by creating business areas that reflect their view of data, and simplify their tasks by creating conditions and joins they will need to use in worksheets.

In this tutorial you created your own unique tutorial database user, an EUL, a business area and a summary folder. You can now delete all of these objects from the database.
