Are Object oriented databases still in use?

Question

Quite a while ago, I heard about Object databases. Cool concept and all. Now, with the event of ORMs everywhere, does anyone still use any of the Object oriented Databases s

Answer 1

In fact, database systems are one of the areas that fundamental changes are really hard. Billions of dollars are spent on relational database systems and they are working pretty well.

In real life, that's simply not true. A major reason for our problems with databases (I saw a claim 30% of all database rows contain errors) is the use of very primitive typing and validating in SQL. In addition, even though they are named relational, they are very bad at handling relations . The result is denormalized datamodels and resulting update errors.

The reason businesses like relational databases is because they are very predictable. They have to spend a lot of money on them, they need a lot of developers and maintenance doing mostly routine jobs. They fail to see the amount of duplication that could be eliminated as an advantage. The routine work allows developers to absorb the risks of the difficult work. Switching to an OODB would keep the less predictable work.
