A word I have been hearing a lot in GIS presentations lately is schema, and I admit that until recently I only had a slightly vague sense of what it stands for.
One explanation I found here when talking about the “blueprints behind GIS databases’. Well, that makes sense. Time to spend some time thinking about how to improve the schema of my borehole database.
Even better is Chapter 3 of Harmon & Anderson’s The Design and Implementation of Geographic Information Systems.
