Of course. I agree with the points made here and in sibling threads about schemas and sql databases. But I also think it's hard to dispute the fact that most data lives in files and file systems. And I think developers too often compare various no(t only)sql solutions with rdms' - without really considering "file-based sql" (sqlite) - or simply file system/DAV based storage (webdav, s3 and work-a-likes, local files, nfs etc). And again - I think it can be easy to see some examples where files are great (store the images for an image gallery), or where relational model is great (transaction data). But I think it can be much harder to see where file storage, or file storage augmented with some form of index - is beaten by a nosql dbms.
