There are OO databaes. I once worked on one using Java. Forgot the name of it now.
It was easy to program using Java.

http://en.wikipedia.org/wiki/Object_database

"Object databases based on persistent programming acquired a niche
in application areas such as engineering and spatial databases,
telecommunications, and scientific areas such as high energy physics
and molecular biology. They have made little impact on mainstream
commercial data processing, though there is some usage in specialized
areas of financial services.[6] It is also worth noting that object
databases held the record for the World's largest database (being the
first to hold over 1000 terabytes at Stanford Linear Accelerator Center)[7]
and the highest ingest rate ever recorded for a commercial database at over
one Terabyte per hour."
