If you're aware of the basics of data science Let's look at the reasons why data science is crucial to the current IT world.

## A good example of Data Science

Here's a quick overview of two of the examples of the versatility of data science.

**law enforcement:** This scenario the use of data science to aid police in Belgium to know what and when to send personnel to stop crimes. With a limited budget and a huge area of coverage, data science employed dashboards and reports that increase the officers' awareness of their surroundings which allows officers dispersed to stay in peace and be aware of the occurrence of criminals.

**Pandemic fighting:** The state of Rhode Island wanted to reopen schools, however, it was prudent, given the current COVID-19 pandemic. The state employed data science to speed up investigation and trace contact information and allowing a small team to manage an overwhelming amount of calls from concerned citizens. This data helped the state to establish the call center and take preventative measures.

**Driverless vehicles:** Lunewave, a manufacturing company for sensors was looking for ways to make their sensors more affordable and precise. They used machine learning and data science for training their sensors to make them safer and more robust, while also making use of information to enhance their 3D printed manufacturing process for sensors.

**The field of entertainment:** data science permits streaming services to track and assess what users are viewing and what they watch, which helps in the development of new television series and movies. Data-driven algorithms also are used to offer personalized suggestions that are based on the viewing history of the user.
Finance: Credit card companies analyze and mine information to identify fraud, manage the risk of financial loss on credit lines and loans, and evaluate client portfolios to discover opportunities for upselling.

**Manufacturing:** Applications of data science in manufacturing are supply chain management, distribution optimization as well as predictive maintenance to predict the likelihood of problems with equipment prior to when they happen.
Healthcare Machine learning models and other components of data science are used by hospitals as well as other healthcare professionals to automate Xray analysis and aid physicians in diagnosing ailments and determining treatment options in light of previous outcomes for patients.

**Retail:** Retailers analyze customer behavior and trends in purchasing in order to give individual product recommendations as well as specific marketing, advertising, and promotions.
