after the data of all the disabled individuals worldwide are compiled, stored and classified, a large, complex but centralized database can then be formed. and this large database is called "big data" which is authored by Victor Mayer-Schonberger.
and the authenticity of the big data can effectively improve the efficiency to help disabled people and achieve precise P2P help in disability assistance. and governments can use the prediction model based on big data analysis to guide their decision making.
