I have never used GIS software before, but have recently got mapinfo professional 8. I have a database of customer data, including postcodes, in London. I would like to map this data, but have no idea how to even begin. Do I need to create a map? If so how? How will the software map the data, can it use postcodes? Please help, as you can see I have no idea how GIS software works, so I dont really know what to do.
