Before moving ahead in this Data Science vs Machine Learning blog, we will have a glance at the agenda:
How is Data Science used in the real world?
Data Science is simply a proper study of raw data through analyzing and visualizing it. It helps extract necessary business information from the data. Now, instead of talking too much about the theoretical aspects of Data Science, let us understand how Data Science is used in the real world. We will discuss the use case of Zomato that uses Data Science to boost its revenues.
Today, every transaction made by us is recorded and tracked by banks. But, the question is, what is the benefit of doing so? How are banks and merchants able to generate business with the help of the recorded data?
Merchants such as Zomato use software, employing Data Science, to create a data product from the recorded data. The software includes functionalities such as data filtration, customer segmentation, transaction tracking, and many more. It tracks every transaction made by a customer and filters it according to certain parameters. Also, it creates segments for payments made to other merchants as well, such as Swiggy, Dominos, and more. With the help of Data Science, the software can efficiently analyze the data. The visualizations of the customer’s data help understand the patterns of transactions through various modes of payment. By using the methodology of Data Science, merchants segregate customers according to partner banks. Then, this data is provided to banks. This enables banks to provide offers to customers on paying through debit\credit cards. By this strategy, both the banks and the merchants generate mutual profits.

How is Machine Learning used in the real word?
In the previous section of this blog on Data Science vs Machine Learning, we saw how merchants and banks make mutual profits by using the transaction data. Now, we will understand how merchants and banks use Machine Learning for giving a personalized experience to customers and increase their profits.
As Data Science helps analyze and visualize data efficiently, Machine Learning helps in the prediction of events. Various merchants such as Paytm, Swiggy, Zomato, Flipkart, Amazon, and more use ML-based software that helps them generate huge profits. You must have observed how your preferred food-ordering application sends you notifications to buy food at the time you are likely to have your lunch or dinner. The application notifies you to buy dishes from your favorite restaurants. When you click on the notification, it takes you to the app and shows you the following:
1. List of your favorite restaurants
2. Previous orders
3. Time of orders
4. Frequent orders
5. Payment gateway used
6. Ratings you have given for food items and restaurants
7. Amount spent on various orders
8. Restaurants and dishes you may like
9. Best selling delicious dishes with their pictures
10. The best possible time required to deliver the food
In such scenarios, people clicking on these notifications may turn into potential customers if the food item is available at a reasonable price. For providing the food item at a reasonable price, merchants give multiple options, such as a ‘Promo Code’ consisting of offers that the customers can apply and get discounts. These promo codes are given by various payment merchants for their promotion. This is a type of marketing that uses Machine Learning to allow businesses to generate huge profits.
Therefore, the topic ‘Data Science vs Machine Learning’ has increased relevance in the market.
Relation Between Data Science and Machine Learning
We use a combination of both Data Science and Machine Learning for building smart applications that provide techniques for business enhancement. To understand the relationship between Data Science and Machine Learning, let us first look at the mechanism of Data Science for mobile applications and websites with the help of the below diagram:
1. Collecting business requirements
2. Data retrieval: User ratings, comments, and cart history
3. Data processing: Missing values, fake reviews, and unnecessary data
4. Data exploration: Understanding patterns and retrieving useful insights
Now, the next part that comes is Machine Learning.
After the data is prepared using the techniques of Data Science, we create Machine Learning models for using the prepared data. Let us look at the below diagram to understand the mechanism of Machine Learning:
1. Gather the prepared data
2. Create a Machine Learning model using various algorithms that best suit the condition
3. Provide data to the Machine Learning model
4. Train the Machine Learning model with the help of a variety of data
5. Test the Machine Learning model with new data and improve its efficiency
Data Science and Machine Learning are separate fields that coordinate with each other to build systems that add value to a business. They improve and automate the internal working of business processes and their software.
Moving further in this ‘Data Science vs Machine Learning’ blog, let us look at the difference between Data Science and Machine Learning.
