Last time in information systems we looked at sorting databases. Databases are very efficient at searching and sorting large amounts of data. The ways that a database can sort (which we know so far) is either ascending or descending, this means that the data will either be from A-Z (ascending) or Z-A (descending) in numeric this is 1-9 (ascending) or 9-1 (descending). When sorting ONE field this is a simple sort, when sorting TWO OR MORE fields then it is a complex sort.
