The likes of Oracle/SQLServer preallocate the files(s) at database 
creation time, so there will be little or no initial fragmentation.

However, they are typically allowed to grow to accommodate extra data - 
this means that fragmentation over time *can* become a problem for these 
guys too - but looks like we can suffer it from day 1.
