The SODA Competition is an open data innovative application competition hosted by Shanghai Municipal Commission of Economy and Informatization, under the guidance of relevant national ministries. City data is like a bottled soda, gentle on the outside but energetic on the inside. When the idea of data opening becomes a consensus, the value of data will gush out like bubbles from an open soda bottle, and produce enormous practical value. SODA is the acronym of Shanghai Open Data Applications, and it is ready to launch, waiting to be discovered by talented data analysts around the globe, and indeed bring benefit to the people.
