Just to avoid a few misunderstandings here. The fact that DAPLEX is essentially (i.e. can be with some minor syntactical changes thought of as) a declarative language is a well-known and widely accepted fact in the field of database theory. One would actually have to pretty ignorant on the literature on this to think otherwise ,and I haven't met any reputable researcher that disagrees with this. Not that I believe you should accept this on an 'argument by authority', you can check the literature yourself, but it's always useful to know what the consensus in the scientific community is.
