"The major bottleneck in retrieving data from database is the seek time. XML data can be clustered into one sector on a disk drive to greatly reduce the seek time when searching for individual elements, thus speeding performance times. In a relational database, each of the data elements to be searched will be in different sectors of the disk, thus taking a certain time to access each element, thus increasing time spent seeking the data."
Is this argument Correct? Can someone elaborate how can XML data be clustered into one sector and if it is possible,then why cannot be the relational data clustered into one sector?
Thanks
