The legend implies that the poll asks for estimates of budget and revenue allocations: one imagines the questions were what proportion of your marketing budget is allocated to digital? and what proportion of your revenues is attributed to digital?
CouchDB vs MongoDB: An attempt for a More Informed Comparison « myNoSQL
After posting about Scott Motte’s comparison of MongoDB and CouchDB , I thought there should be some more informative sources out there, so I’ve started to dig.
