On a side note, you can hook a Hadoop cluster up to SQL Server if you're into that kind of thing for storage.
They have different columns because it deals with about 600 different tables and the output is what is relevant to the test. I have decided that in this instance, I want to capture all of the results in a single table so that they are centralized. XML solves this issue for me. I can grab the results in XML, and insert them into a centralized table where they can be reviewed later.
TL;DR XML can solve some data structure issues where you don't always know the final output until it shows up.
Also, I believe that in SQL Server, the old (ANSI 89) style of joining (joining in the where clause) was deprecated and isn't optimized anymore so you'll get crap performance because all of the tables are actually cross joined before the filtering happens. The explicit join forces relationships to be accounted for first which can help keep the amount of memory needed down.
One last thing, how long does it take to adapt a new standard? The explicit join has been the standard since 1992.
