Data is an integral part of the modern IT industry, often referred to as the "new oil" for its valuable role in driving business growth. Companies collect vast amounts of data every day from their customers and users, but what is the purpose of all this data?
Data science is the field of study that deals with the extraction of meaning from large amounts of data. A Data Scientist is the professional who applies this science to data. In this article, we will cover:
Now that you have an understanding of what data science is, let's dive deeper and explore its significance through a case study.
Data science is no longer just a future trend, it is already a dominant force in the industry. Companies collect vast amounts of data, and data scientists use advanced techniques to extract valuable insights from it. These insights are used by companies to make important business decisions. To further illustrate the power of data science, let's take a closer look at a real-world case study.
A milk farm located in the city was experiencing steady annual growth in revenue. The owner was dedicated to understanding customer feedback and collected monthly ratings from customers. This was successful for several years, but the owner noticed a sudden decline in the average rating. With a large customer base, it was not feasible to survey every consumer, so the owner asked nearby customers for their input. They reported that they did not have any issues with the milk.
To find the root cause of the problem, the owner sought the help of a Data Scientist. The data scientist analyzed the monthly rating data provided by the owner and noticed that the ratings were significantly lower in July, August, and September. By plotting the data and extracting weather data for the city, the data scientist discovered that the problem was related to the rainy season. However, as the owner had mentioned, nearby customers were satisfied, so the problem was with distant customers.
The data scientist, being an expert in his field, hypothesized that the problem could be related to the containers used to deliver the milk to distant customers. The more the container was exposed to rain, the more likely it was that water would mix with the milk. The owner was able to use this information to make changes to their delivery process, which solved the problem and improved customer satisfaction.
The owner of the milk farm conducted an investigation and found that the data scientist's hypothesis was correct. He made the decision to change the position of the container's opening from the top to the bottom, and sealed it to prevent water from entering. This decision proved to be successful and helped the owner retain thousands of customers.
This case study highlights the importance of data in making strategic decisions. It emphasizes the value of data science, the field of extracting meaning from data, and its growing significance in today's world. Companies worldwide collect various forms of data available online, analyzing and tracking online behavior to provide personalized recommendations.
Companies collect various types of data on our online movements, both with and without our consent. This data can be classified into three categories: structured, unstructured, and semi-structured data.
Understanding the different types of data and how to effectively analyze them is crucial for businesses to extract meaningful insights and make informed decisions.

Data science plays a vital role in helping businesses, regardless of size, extract valuable insights from data and make informed decisions. Examples of this can be seen in everyday experiences such as search engines like Google suggesting what we will search for before we even finish typing our query, which improves user engagement and retention. This is made possible through the application of data science to the large amount of data that Google has collected. Similarly, food delivery service Zomato aims to deliver food within 10 minutes by analyzing data on past orders and pre-stocking nearby locations with the most popular items.
The benefits of data science can be grouped into three categories:
Data Science is a process of extracting insights and making informed decisions from large and complex data sets. The various stages of this process include:
Data Science and Machine Learning are closely related fields that work together to extract insights from large amounts of data. Data Science encompasses all aspects of analyzing and visualizing data, while Machine Learning specifically focuses on developing predictive models. Machine Learning Engineers focus on the technical side of creating and implementing these models, while Data Scientists use these models to perform predictive analysis and make strategic business decisions. Both are essential for understanding and utilizing the vast amounts of data that companies collect today.
Data Analysis and Data Science are two distinct but related fields in the technology industry. Data analysts primarily focus on analyzing and interpreting existing data through techniques such as data visualization and statistical analysis. They provide insights and reports on the collected data. Meanwhile, Data Scientists take a more strategic approach by determining how data should be analyzed, stored, and manipulated in order to solve specific business problems. They also create advanced methods and models for data analysis, manipulation, and prediction using techniques such as machine learning and statistical modeling.
Data science plays a crucial role in the IT industry, where business analysts collect and provide data to data scientists to solve specific business problems. Data scientists analyze the data and use machine learning techniques to build models that can provide valuable insights and predictions. These insights are then translated into actionable plans by business analysts, who present them to the stakeholders in a clear and easy-to-understand format. This process of data collection, analysis, and implementation helps companies make data-driven decisions that can optimize their operations and increase revenue.
Data Engineering and Data Science are two distinct but related fields within the IT industry. Data Engineers focus on the infrastructure and systems that support the storage, collection, and manipulation of large data sets. This includes tasks such as designing and maintaining databases, creating data pipelines, and implementing data storage solutions in the cloud. On the other hand, Data Scientists use this infrastructure to analyze and extract insights from the data.
