[comp.object] **** Query language for object-oriented database ? ****

Is there any query language for object-oriented/frame style organized
database? I know somebody is doing it using SQL.

For example, a database may be organized like this:

             { man: name, age; }
             { john: isa man, name "john", age 21; }
             { bob: isa man, name "robert", age 34; }
             ...

and they can do: SELECT name FROM man WHERE age > 30;

But SQL may not be the best choice for this kind of database.
Is there any kind of survey done on this issue? Has someone implemented
something other than SQL?

Thanks a lot.
