the application of big data. Big data can be applied to all walks of life, analyzing and sorting out the huge data collected by people, and realizing the effective use of information. Take this major as an example. For example, looking for major genes related to milk yield at the gene level of dairy cows, we can first scan the whole genome of dairy cows. Although we have obtained all phenotypic information and genetic information, due to the huge amount of data, it is necessary to adopt big data technology to analyze and compare and mine major genes. There are many examples.

the significance and prospect of big data. In general, big data is a large, dynamic and sustainable data, through the use of new systems, new tools, new models of mining, so as to gain insight and new value. In the past, in the face of huge data, we may be blind and visible, so we can't understand the true nature of things, so we can get wrong inferences in scientific work. With the advent of the era of big data, all the truth will be presented to us.
