Oracle provides a lot of XML functionality in the database. This entry will cover the different tools Oracle provides and future entries will get into the details of each.

The three primary XML tools that oracle provides are: XML Developers Kit (XDK), XML DB and SQL Extensions for XML (SQLX and XMLType). Below is a definition of each.

XDK

The XDK is a complete XML development toolkit that was introduced for 8i. I think the first version was labeled XDK9i but the toolkit actually was available for 8i. I remember using the beta product.

This is a continuation of Object Orientation in Oracle. I guess I should have called it the Sorcerer of OOO. This is a technical entry.

Anyway, in part 1 I covered the basics of creating an Oracle object type and showing how it compared to a Java class. Today I’m going to cover the concepts of comparing objects and Inheritance. In part 3, I will cover type evolution and Polymorphism and in part 4 I will cover Object Views and Object Tables.

Comparing Objects

Many times, you will be working with multiple instances of the same object.

I could have called this OO In Oracle: A Techie’s View. But the Sorcerer of OO is a much cooler title. You have to pronounce OO as ooh! as in Ooh and Aah!

What is OO? OO stands for Object Oriented. OOD is OO Design, OOA is OO Analysis and OOP is Object Oriented Programming. Oracle is an ORDBMS, an Object Relational Database Management System. In this article, I am going to present a sample java class and show how you would implement the same class in Oracle. This is a technical article comparing Oracle objects with Java.
