Introductory Guide to Data Science

We are living in an era of high competition where information is the key to getting our grip on the market. This information is generated by the massive amount of data collected from applications, websites, and many other sources. So, the data generated by these sources can be structured or unstructured. We need to process this massive amount of data. This can be done by designing algorithms and tools that we can use to draw out meaningful insights from the data and then make productive strategies by understanding the patterns so that we can find new market trends, enhance productivity and efficiency to make a good place among competitors. This is where Data Science comes into play. Data Science is the study of data. It involves developing methods of recording, storing, and analyzing data to effectively extract useful information.

It’s not only about business or markets where Data Science is useful but it can also be used in predictive analytics like in weather forecasting. Data collected from satellites and radars can be used for predicting the weather conditions and occurrence of natural calamities. It will help us save many lives by taking appropriate measures before time.
