What Is Data Science and How Does It Work?

Data science is a field of study that works with large amounts of facts and uses cutting-edge tools and techniques to uncover hidden patterns, extract useful data, and make business decisions. To create prediction models, data scientists use complicated machine learning algorithms. Here, in this blog we will discuss about what is data science and to know more about why data science, join Data Science Course in Chennai at FITA Academy.

Data Science Prerequisites

Here are some technical terms you should be familiar with before diving into the world of data science.

1. Artificial Intelligence:

The backbone of data science is machine learning. Data scientists must have a strong understanding of machine learning (ML) as well as a fundamental understanding of statistics.

2. Creating models:

Based on what you already know about the data, mathematical models allow you to make quick calculations and predictions. Modeling is a subset of Machine Learning that entails determining which algorithm is best for solving a particular problem and how to train these models.

3. Information about statistics:

The foundation of data science is statistics. With a firm grasp on statistics, you can extract more intelligence and produce more relevant results.

4. Computer programming:

A successful data science project necessitates some level of programming. Python and R are the most widely used programming languages. Python is particularly popular because it is simple to learn and supports a variety of data science and machine learning libraries.

5. Databases: 

A good data scientist should be able to explain how databases function, how to manage them, and how to extract information from them.

What Position Do You Hold in Data Science?

Data science allows you to focus on and specialise in a certain part of the discipline. Here are some examples of how you can get involved in this interesting, fast-growing profession.

Data Scientist

• Determine the problem, the questions that need to be answered, and where the data may be found. Also, they mine, sanitise, and show the important data.
• Programming skills (SAS, R, Python), storytelling and data visualisation, statistical and mathematical skills, Hadoop, SQL, and Machine Learning knowledge are all required.

Data Analyst

• Analysts are responsible for bridging the gap between data scientists and business analysts by organising and evaluating data to answer the organization’s questions. They convert the technical analyses into qualitative action items.
• Statistical and mathematical skills, programming skills (SAS, R, Python), and data wrangling and data visualisation experience are all required.

Data Engineer:

• Data engineers are responsible for building, installing, managing, and optimising the company’s data infrastructure and data pipelines. Engineers assist data scientists by assisting with data transport and transformation in preparation for queries.
• NoSQL databases (e.g., MongoDB, Cassandra DB), programming languages like Java and Scala, and frameworks are all required (Apache Hadoop).

Applications of Data Science

Data science is now being used in practically every business.

1. Healthcare

Data science is being used by healthcare companies to develop advanced medical tools that can identify and cure ailments.

2. Gaming

Data science is currently being used to build video and computer games, which has elevated the gaming experience to new heights.

3. Image Recognition

One of the most prominent data science applications is detecting objects in photos and identifying patterns in them.

4. Recommendation Systems

Netflix and Amazon make movie and product suggestions based on your viewing, purchasing, and browsing habits on their platforms.

5. Logistics

Logistics organisations employ data science to optimise routes in order to assure faster product delivery and increase operational efficiency.

6. Fraud Detection

Data science and related algorithms are used by banking and financial institutions to detect fraudulent activities.
