Most of you guys are aware of one or two GIS systems. But what about the functionalities of others? How can you compare these? @Dragons8mycat has done some great work in providing a way to huge excel sheet where he compares nearly all of the available GIS systems.
As we are running several projects besides this blog we ran across CartoDB. CartoDB is more or less a nice GUI that serves you either a table of your data or a map that refers to this data. As a user you register yourself and you are able to use the service for free if one can waive the feeling of privacy.
