Esri software

ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri.

ArcView, now referred to as ArcGIS for Desktop Basic, is the entry-level licensing level of ArcGIS Desktop, a geographic information system software product produced by Esri. It is intended by Esri to be the logical migration path from ArcView 3.x.

ArcInfo (formerly ARC/INFO) is a full-featured geographic information system produced by Esri, and is the highest level of licensing (and therefore functionality) in the ArcGIS Desktop product line. It was originally a command-line based system. The command-line processing abilities are now available through the GUI of the ArcGIS Desktop product.
