To that end, it is often the simplest (most readily available, best documented) tool for the job.

Not to forget the things DBs do beyond pure persistance. I mean sql might very well be easier/quicker in building reports compared to querying all that data from various genservers. Also rolling your own data indexing might not be your thing.
