I have been using databases for years and have used QGIS since 1.8 for general mapping. I know it can use additional data attached to the geographic data via a union query to display lots of different things. I have map areas where population density would be nice to display using different background fill colors bases on that density. I just need a bit of a boost getting the idea as to how to start and which way to go.
I have been using the program with SpatiaLite database. Do I need to go tto the PostGis db? Most of my other data is currently in MySQL. Thanks for amy advice / guidance!! Chuck
