Data science is an interdisciplinary field that extracts knowledge from numerous structural and unshaped data, using scientific methods, machine-learning algorithms, and big data. As we know the Data Science industry is growing, it is still very emerging but very promising. This industry is expected to grow by huge amount in coming time, and data science as a field is still unknown to many of us. In early days the extraction of information from data has been done by the use of statistics. However there are many reasons to consider Data science as a new field. First, the raw material, the data part of Data Science, is increasingly diverse and unstructured text, images, and video, frequently arising from networks with complex connections among its entities. In this research paper we are going to discuss different application of data science.
