but putting it on disk still requires an on-disk format. whether it's the database using a raw partition divided into pages and segments or files mapped out via inodes on disk, a format will still exist. it's the difference between chasing pointers around on disc versus a system where a data structure is queried for addresses and then a lookup (or lookups) are made on disk using those addresses into the on-disk format. again, depending on the characteristics of your data and how you access it, one system will likely be faster than the other. it's pretty obvious which one will take more RAM and disk space ;-) > Microsoft's vested > interest in this would be that they can further increase the strangle-hold > they have on customers with proprietary file formats.
