This article reviews graph databases, as a storage technology similar to relational databases like Postgres and document stores like MongoDB. We review the basic concepts of graph DBs, some example engines, use cases in which treating data as a graph can be useful. We explore a project that uses a graph DB to store data about cloud systems, and we use a graph DB to model a router+firewall’s configuration file, including queries over the stored data, which we also compare to a similar Postgr...| blog.jreyesr.com

Here are some graphs: All graphs made with graphviz (source) Graphs are ubiquitous in software engineering: Package dependencies form directed graphs, as do module imports. The internet is a graph of links between webpages. Model checkers analyze software by exploring the “state space” of all possible configurations.| Hillel Wayne
