A United Nations reference is worth a thousand words:

UN Comtrade, the trade database of the United Nations, states:
“ABRAMS world trade wiki is the first to introduce a unique business intelligence portal, where UN Comtrade macro-economic data is connected with customs trade data. [...] ABRAMS world trade wiki is used by governments, policymakers, investors, entrepreneurs, researchers, logisticians and consultants as an important resource and instrument to generate knowledge out of big data.”
