I don't have much experience with numerical simulations. What part of them should not require many loops in your opinion ? Matrix calculations ?

Some differences between network and relational databases are (in my opinion :):
- the network ones seems ad hoc ; the relational ones have a foundation in math right from the start
- the network ones exists ; the relational ones are incomplete and expensive - the network ones are based on sequencial access ; the relational ones are based on random access

The OO ones are supposed to be a cross of network and relational, easyer to use than both of them.
The "semistructured" ones are supposed to cure the flaws in the OO ones. I don't see how they do that given the "fact" that "we" have not been able to implement the relational ones in the first place.
