Sorting also can streamline processing. comScore sorts URL data to minimize Web site taxonomy lookups. Instead of loading the 40 URLs for Web site pages in the order they were visited during a session, sorting might reveal that 20 of those pages were on Facebook, 12 were on GMail and the balance were at NYTimes.com.

It’s possible to sort data with SQL statements, and custom scripts, but sorting is also a common feature in data-integration software from IBM, Informatica, Oracle, SAP, SAS, Syncsort, and others. At truly large scale, Hadoop is an option for sorting and other processing steps.
