Ask HN: Why are relational DBs are the standard instead of graph-based DBs?

One downside of both hierarchical and network (graph) models that is not mentioned either in the post or parent comment is, "access path dependence". Network model allows multiple paths but basically just forestalls the issue.

As to sibling comment question about how to keep up on this stuff, the preceding info was in the "tar pit" paper that has been discussed a lot here on HN. So I'd say, your already doing it. Continuing education is part of any profession and this is probably a better way than some.

Yes. I think that this access path independence is an essential part of the relational query approach, (of which SQL is one example), being high-level. And once you have such a language, query optimization becomes essential.

Did you mean Mosley and Marks' "Out of the Tar Pit" http://curtclifton.net/papers/MoseleyMarks06a.pdf?
