In addition to the points made by Carl...
I am suggesting that in an ideal OODB, there exists a basic object. When this object is put together with other instances of the basic object, one should be able to represent any imaginable data.
In a relational database, the fundamental unit of storage might be the table, possibly a table with one row and one field.
A oodb represents data starting at a very granular level, the object, which gives it flexibililty especially with complex/variable data structures.
A rdb represents data starting at a higher level, the table, which gives it efficiency with data that is mostly uniform.

I believe oodbs, such as XDb, will eventually provide similar querying
abilities and perform them in less time.

An oodb, such as XDb, will provide mass updates in the near future and
perform them in less time.
