There is no shame in not being able to do particular things as well as the best candidates. That's life.

What actually happened was that right across telecoms, for these particular systems, the stock RDBMS were suffering horrendously (Oracle, Ingres, Informix etc) .

It just so happened that OODBs emerged at that particular time, and solved this one particular problem very well indeed.

If the time-line had been in the late 1980s (as it was for the first similar type of system I worked on that RDBs were having grief) , something else would have been devised (OS "flat file" structure/persistence etc - which notably was/is used for these systems but on resource-constrained embedded envs) .
