Navigating objects

Dr. Stonebraker has also provided a way for classifying DBMSs based on performance on complex data. He mentioned this during a question and answer session at the Object/Relational Summit in Boston in August, 1997. He said, "My point of view is that if you want to navigate your objects in C++, object databases do that blindingly fast -- way faster than a relational or an object-relational engine." (This was before Java became popular.) Listen to Dr. Stonebraker: Stonebraker.wav (178KB).

Let's look at what it means to navigate objects. The following figure shows a few instance objects that are part of a database of parents, children, and addresses. The arrows show the relationships among the instance objects. Moving from one instance to another along the arrows is navigation. Languages such as C++ and Java provide ways to navigate among objects. The speed of this navigation is what Dr. Stonebraker describes as the strength of ODBMSs.

Navigating objects

Querying object structures such as this requires navigation. See the query navigation page and then we will create a better DBMS Matrix.
