I was wondering for a while now, what should be the hierarchy of my GIS knowledge or better to say, learning curve in domain of open source GIS.
Should I start with Geoserver and PostGIS then transition to OpenLayers and finally wrap things up with GeoEXT or other way around?
To be fair, I started with OpenLayers (2.12) using books from Edin Hazzard and Antonio Perez Santiago, but now, as time progress I'm not so sure after all about my learning path, should I picked Geoserver or PostGIS first ?
( I know it's a dumb question but I need some insights about that topic )
Forgot to mention it that I have fair amount of knowledge in desktop softwares such as AutoCAD Map3D and ArcMap 10.x (recently started with QGIS)
