Just because you use a relational database doesn't mean you have to make relations.

A flat table is simple enough of course it's hugely inefficient and defeats the point of having a relational database in the first place but it works.

If all it is is spreadsheets why not just knock something up that deals with flat files? This eliminating databases all together?

Wondering how to store images that way? Look up datauri stuff. Basically store images as base64 strings. Store the format and the browser (firefox/IE) converts it back to an image.
