While there’s countless relational databases out there for practice, there’s not much in the way of graph databases. It is my intent to share my graph databases with the world in hopes that it removes the friction associated with your learning.
US Capitals is a popular data set for working with graphs. Nodes identify a state capital. An edge connects a capital in one state with the capital of a neighboring state. Only the lower 48 states are present. While the data is readily available, I was unable to find TSQL scripts to create the graph using SQL Server 2017 graph database. I created those scripts and have made them readily available on GitHub.
I’m interested in the forthcoming post on Dijkstra’s algorithm; I think the last time I saw that was my undergrad days.
