Creating a data structure for your data in a Scratch layer, a GeoPackage, or PostgreSQL using QGIS

In this this video I will Demonstrate how to create a Data structure to store your geospatial data using QGIS. I will demonstrate both the spatial and non-spatial data types available in Temporary scratch layers, a GeoPackage and a PostgreSQL database.
