This module deals with the new data type structures and explains their performance implications for Oracle8 databases. Prior to the introduction of Oracle8, critics were comparing the added functionality of the new object-oriented databases with the traditional relational database model.
With Oracle8 we see several new object-oriented data structures that promise faster performance. In this module, we will take a closer look at these new features.
By the time you finish this module, you will be able to:

1. List the added functionality of each of the new Oracle8 data structures
2. Create an Abstract Data Type (ADT)
3. Create a nested table
4. Define a table with a VARRAY

The next lesson reviews the new Oracle8 data structures.
