SuccessFactors database

When I work in SAP ERP system, I always checks the values, for example when I create a new report.

This check I do directly in the database, transaction code SE16, to make sure it works OK.

I have seen SAP standard reports that not works as it should, and therefore I'm always a little suspicious.

In SF, is there any way we can reach the database, to make sure nothing is missing, or do we have to belive that everything works as it should?
