Data Science


Every company and organisation deals with huge amounts of data that they receive on a daily basis. Data Science is a multidisciplinary subject that uses different processes, advanced algorithms, and other complex scientific methods to extract information  and provide insights from structured and unstructured data to any company or organisation. 


In 2008, the term “Data Scientist” was first used when companies first realised that they require professionals to handle huge amounts of data everyday. Data Scientists are able to discover relevant questions, acquire and organise data from different sources, find solutions from the available results, and use them for the betterment of the business.


Today, data science is used in many fields like Healthcare, Targeted Advertising, Gaming, Augmented reality, Finance etc. Before data science was even a well-known industry phrase, financial organisations understood that analytical, inquisitive and solution-oriented experts could argue for statistical analysis, forecasting, and risk analysis over huge volumes of consumer and financial information may be required. 


Finance is one of the most critical fields to handle in the field of Business, as it requires a lot of time, accuracy and effort. Financial data science is required for management, market analytics, risk analytics, fraud detection, customer management etc. There are increasing numbers of transactions presently underway over the Internet and stunning volumes of financial data are created every day.


In this article, some applications of Data Science in the field of finance are described. Let us elaborately discuss those applications below.

  1. Risk Analytics


In every business, the authority needs to make some important and unpredictable decisions,  and hence it is very important to predict and analyse the risks beforehand. It is very important for large companies as one wrong decision can lead to huge loss. Using data science, these risks are analysed and strategic decisions are taken.


Problem solving abilities, mathematics and statistics are required for risk analytics. The data scientist studies all the available unstructured data like financial transactions and customer information, organises them, and identifies and prioritises the risks present in them. Risk Management is one of the most important applications of Data Science.



  1. Customer Data Management


Every business has a set of customer base, with which comes huge amounts of customer databases. Due to the large amount of online and offline transactions and social media, there are both structured and unstructured data that needs to be managed and stored. 


Data Science and Big data are used to process and analyze them. Big Data plays a major role in Business Intelligence and through various machine learning and AI tools like data mining, Natural Language Processing (NLP) and text analytics, it can provide insights of customer behavior and feedback. That way, the company can have a knowledge of market trends and financial markets.
