What is the science of data?

In 2013, a pioneering study estimated that 90 percent of the world’s entire data were generated in the past two years. Allow it to sink in. In just two years, nine times the amount of knowledge we gathered and processed as the previous 92,000 years of humanity combined. And it doesn’t slow down. We have already produced 2.7 zettabytes of data, and this number is expected to be astonishing 44 zettabytes by 2020.

What are we doing with all this information? How are we helping ourselves? What are applications in the real world? These issues are the field of data science.

Each organization will say it does a kind of data science, but what does that mean, exactly? The discipline is overgrowing and revolutionizing so many sectors. It is difficult to fence with a systematic concept of its capabilities, but data science is dedicated to extracting clean knowledge from raw data to formulate operational insights.


How do you work in data science?

Data science involves an abundance of disciplines and expertise to provide a holistic, thorough, and refined raw data analysis. Data scientists should be skilled in everything from data engineering, mathematics, statistics, and advanced computing to effectively search through mixed masses of information and communicate only the most essential bits to innovation.

Data scientists also rely heavily on artificial intelligence to establish patterns and make predictions using algorithms and other techniques, particularly its machine and deeper learning subfields.

In general, data science has a five-stage lifecycle of 1:

  1. Capture: acquisition of data, data entry, receipt of the signal, extraction of data
  2. Maintenance: data storage, data cleaning, data staging, data analysis, design of data
  3. Process: mining of data, clustering/classification, data modeling, data synthesis
  4. Communicate: information reporting, visualization of data, intelligence, decision making
  5. Data: quantitative analysis, analysis predictive, regression, mining of text, qualitative analysis.


All five phases involve various strategies, programs, and skills, in some cases.

Uses in data science

Data science helps us achieve some essential objectives that were either not feasible or took a lot more time and energy only a couple of years ago, for example:

What would I use for DATA SCIENCE?

  • Identification of anomalies (fraud, disease, crime, etc.)
  • Automation and decisions • (background checks, creditworthiness, etc.)
  • Classifications (this may mean emails may be “important” or “junk” on an email server)
  • Projection • (sales, revenue, and customer retention)
  • Identification of trends (weather patterns, financial market patterns, etc.)
  • Acknowledgement (facial, voice, text, etc.)
  • Suggestions (based on learned preferences, recommendation engines can refer you to movies, restaurants, and books you may like).

There are also a few examples of how companies use data science for innovation in their industries, the development of new goods, and their environment’s efficiency.

Treatment for health

A massive network of data, ranging from EMRs to clinical databases and personal fitness trackers, has brought many breakthroughs in the healthcare industry. Medical practitioners will now find new means to understand illnesses, practice preventive medicine, diagnose diseases more quickly and discover new therapeutic options.

Auto-driving cars

In their latest generation of autonomous vehicles, Tesla, Ford, and Volkswagen are now introducing predictive analytics, using thousands of tiny cameras and sensors to transmit information in real-time. Machine learning, predictive analytics, and data science enable self-driving automobiles to modify speed limits, avoid risky road changes, and carry passengers along the most rapid path.

The logistics industry

The ORION (On-Road Integrated Optimization and Navigation) tool uses data science-based statistical modeling and algorithms that provide optimum routes to supply pilots based on the weather, traffic, construction, etc. It is estimated that data science will save the logistics company up to 390 times.

An enjoyment

Would you ever wonder how Spotify can recommend the perfect song for which you are in the mood? Or how Netflix knows what shows you want to binge on? Using data science, the music streaming giant will carefully guard lists of songs based on the music genre or band that you currently belong to. Really into cooking lately?

Financial finance

For example, the JP Morgan Contract Intelligence (COiN) platform uses Natural Language Processing (NLP) to process and extract essential data from around 12,000 commercial credit agreements a year. Through data science, it takes approximately 360,000 hours of manual labor to complete


In all industries, data research is valuable, but it may be the largest in cyber-security. Kaspersky uses data science and machine learning to identify more than 360,000 new malware samples every day. Instantly detecting and learning new cyber-crime techniques utilizing data science is crucial for our safety and security in the future.

Data Science Prerequisites

Here are some of the technical terms you need to know before learning about data science.

1. Learning Machine

The foundation of data science is machine learning. In addition to basic statistical skills, data scientists need to have a strong understanding of ML.

2. Models

Mathematical models allow you to calculate and predict what you know about the data quickly. Modeling often forms part of ML and includes identifying the most appropriate algorithm to solve a particular problem and how these models can be trained.

3. Statistical information

Statistics are central to data science. A robust statistical handle can help you gain more insight and more accurate outcomes.

4. Programmable.

Some programming is necessary to perform a data science project effectively. Python and R are the most common languages for programming. Python is especially popular because many Data and ML libraries are easy to learn and support.

5. Bases of Data

A capable data scientist, you need to understand how databases operate, how they are managed, and how data are collected.
