A theme is the geographic data you work with. They are composed of points, lines, or polygons that are individually called features . A table is a data file that contains rows of information about geographic features, one row to each feature, where each column represents one attribute .
Attributes contain geographic and non-geographic data.
For instance, geographic data would be a coordinate, while non-geographic would be population. Other tables can be linked or joined to themes. A view is a workspace where you load, arrange, analyze, and edit themes. Themes are overlaid one over the other to create a composite map. In the view you can alter the way the data is displayed, and save these settings and the reference to the source file in your project file.
