Database solution can have many relations, scripts, layouts. There can be missing field, missing script,... and it is very hard to find those errors.
FileMaker Advanced could have a special report with all errors detailed (missing and wrong parts in each table, script, layout....). I know that some functionality can be reached with external utilities, but I think that all users of FileMaker Advanced deserve some basic errors report. In other database platforms, errors are clearly reported, in FileMaker, they are hidden and you have to find it out.
