With a GIS and spatial data you can ask spatially related questions:
The spatial distribution of object(s) or theme(s). Example: Where is x? How is x distributed?
The relationship between the spatial distribution of objects or themes. Example: Where is x in relationship to y?
The association of objects or themes in an area. Example: Is there a correlation between the distribution of x and the distribution of y? Could x be causing y?

It is, first and foremost, a powerful analytical tool with a spatial "awareness" that allows you to analyze spatial data and answer complex spatial questions.
