SQL is wildly powerful and important, but it's also got clear deficiencies for data traversal and manipulation.
I see it on a spectrum between declerative and imperative data structures, and where I think most people go wrong with it is trying to create a monolithic solution to a broad spectrum of problems. I think you need a graduated approach where each data layer is simplifying and satisfying the next, so you're using Tables, Procs, Views, and in-memory constructs in concert. The database is a powerful tool, and SQL is just part of that bigger puzzle :)
