A GIS integrates common database operations such as query and statistical analysis with the ability to see how data relates in space and time, "on Hall's Hall (1999)" stresses the point that "GIS are much more than simply computer mapping system and can do much more than merely out putting improved digital versions of static paper based map, GIS blend map production, image presentation and statistical analysis capabilities into a powerful analytical tool that can be applied to a variety of Problems."
