Big data technologies.By collect, store, manage, analyse and dig and show the data we can find some useful or interesting rules and conclusion.For example, we can get those records for the pedestrians of the bus every day. So to analyze those records we can know the outgoing rules for those civilized people in Beijing so as to improve the transport situation of the city.But those records data are not easy to get. We need to support those data so as to improve the value of the data by storage and compute.So the most important thing is not about the data technology itself, but we need to realize two standards the first one is about enough quality of data and enough value of the data the second one is about whether or not we find the correct application of the data technology in the affairs.So the technology of big data are and the core values of data and it includes the several steps from collection and transportation storage analysis Application and so on.
