The complete process of extracting useful information from unstructured data, including diverse ideas including statistical analysis, data analytics, machine learning algorithms, data modelling, and data pre-processing, is referred to as data science. If you are here to know What are the use cases of Data Science? Learn Data Science Course in Chennai at FITA Academy with the assistance of Data Science professionals and with career guidance.
Data science is a branch of study in which data is analysed using sophisticated statistical and mathematical principles and machine learning techniques in order to derive insights that can be used to address problem formulations or commercial issues.
Prerequisites for Data Science
To successfully implement data science solutions within an organisation, a number of conditions must be satisfied. The following are some requirements:
Programming Knowledge
Professionals must be familiar with programming languages like Python or R programming in order to perform the statistical analysis and computations necessary for data science procedures. It is simple to create machine learning models from scratch with the help of scripting skills and library support.
Statistics, Probability, And Linear Algebra
If you really want to make a career in data science, you must have a solid understanding of both descriptive statistics and inferential statistics. You can come to several conclusions and understand the information available using statistical analysis. As an illustration, we discussed about determining whether a time sequence is stationary through hypothesis testing.
Understanding complicated machine learning algorithms requires a strong foundation in linear algebra and probabilities. Being aware of these concepts will make it easier for you to understand how different machine-learning algorithms operate.
Why Data Science?
Right now, qualified data scientists are in high demand across all industries. They rank among the IT industry’s highest-paid professionals.
The Internet of Things (IoT) market has experienced rapid expansion in recent years, which has caused 90 percent of today’s data to be generated. With the expansion of IoT, the daily data generation rate has increased to 2.5 quintillion bytes.
How Does Data Science Work?
Following is an explanation of how it functions:
- Raw data that explains the business issue is gathered from many sources.
- Data modelling is done to create optimal solutions that best describe the business problem through different statistical analysis and machine learning methodologies.
- Data science-based insights that can be used to solve business difficulties.
Let’s understand this with an example:
Gathering Raw Data
A business wants to know how people feel about its brand on social media. They choose to gather information through the Twitter API, which offers tweets about their brand.
Data Modeling
Data scientists preprocess and sanitise Twitter data using statistical analysis and machine learning techniques. They take out essential data including user demographics, sentiment scores, and engagement analytics. After that, the data is transformed into a structured format for analysis.
Actionable Insights
To gain insights, data scientists analyse structured data. Within the Twitter data, they find patterns, trends, and correlations. For instance, they might discover that younger populations exhibit more positive sentiments during particular events. The organisation may now use this insight to enhance its brand impression and engagement tactics. Learn Data Science Online Course with placement assistance by industry experts.

Industrial Applications of Data Science
- Internet search: Data science techniques are used by every search engine, including Google, to instantly deliver better results for searched queries.
- Targeted advertising: Due to the targeted nature of digital ads and the usage of data science algorithms, which are based on the user’s prior behaviour, they have higher call-through rates (CTR) than traditional commercials.
- Recommendation systems: Massive internet businesses and other companies eagerly employ recommendation algorithms to market their goods based on the user’s past search results and preferences.
