I have no interest in becoming an expert on them but as I am messing about with the cs-cart lark I sometimes come up against this dark area of knowledge which I would like to be able to see into a bit - even if just to put cs-cart into context.
For example people sometimes say “run this query”.
So allowing for the fact that it is only to bring some enlightenment and to sit with using cs-cart can anyone recommend a book or online resource that would fit the bill without being top heavy.
