Discover What Data science Is: Basic Introduction and Its Application

Data science is a research field that combines subject mastery, program inclination, and information on arithmetic and measurement to remove significant experiences from data. Data scientists apply AI computation to numbers, text, photos, videos, sound, and more to provide an artificial intelligence (AI) framework for performing tasks that typically require human knowledge.

In this way, this framework creates an experience where auditors and corporate clients can become significant business honors.

While data science certification is nothing but a calling, it has come a long way over the past 50 years. The stumbling block in the historical background of data science suggests a long and winding road back to 1962 when the mathematician John W. Tucky predicted the impact of current electronic processing on data exploration as an exact science.

However, data science today is far from what Tukey imagined. Tukey’s predictions came long before the explosion of big data and the ability to conduct overwhelming and confusing research. Overall, it was not until the 1964 New York World Fair that the mainframe {Programma 101} was distributed to the average person. All the analyzes that have been carried out are simpler than is currently possible.

In 1981, IBM has shipped its first computer. The Mac didn’t fall far behind, bringing in the GUI mainframe in 1983. As a result, processing seemed to be progressing much faster, so companies could easily gather more data. However, it will still take about twenty years before they start converting these data into data and information.

Why do we need data science?

Until now, the data is still structured and small. These can be analyzed either manually or with the help of simple tools and algorithms. Thanks to technological developments, we are now generating even more data. These are often semi-structured or completely unstructured. For example, it is estimated that more than 80% of company data is unstructured. It will only increase.

To better understand this growing unstructured data mass, we need more sophisticated analysis tools and sophisticated algorithms. Data science is the process of using these powerful tools to make sense of large amounts of unstructured data. As the amount of unstructured data increases, so does data science.

Steps Followed in Data Science

1. Data Collection – The first stage of this process is data accumulation. Usually organized, unstructured, or semi-organized.

2. Modify Data – Once you have the data, this is the ideal opportunity to dump it. “Raw data” is cleaned and changed to a suitable configuration in exchange for most of the incentives. This is perhaps the longest progression. Data researchers report that cleaning data is about 80% of the time throughout the cycle.

3. Data Analysis – Once the data is cleaned, this is the ideal opportunity to explore it through key quantifiable calculations and models.

4. Data visualization – When there is a lot of data to manage, constructing a visualization or chart is the most ideal approach to researching and transferring results.

5. Forecasting – Machine learning calculations help you gain experience and predict future models. Apart from predictions, these advancements can help you create new elements and cycles.

6. Repeat Insights helps give more weight to continuously improve model results and deliver comfortable performance and accurate results.

Data science applications

As is clear at this point, data science is a broad term, as are its applications. Almost every app on your smartphone lives off of data. With that in mind, its ubiquity in essence makes it difficult to calculate all data science applications.

Let’s look at the broad areas where the magic of data science is used:

1. Search the internet

How does Google return * accurate * search results at a glance? Data science!

2. Recommendation system

From “People You May Know” on Facebook or LinkedIn to “People Who Buy This Product Like …” on Amazon, to your daily selected Spotify playlist, and even to “Recommended Videos” on YouTube, all with thus supported by data science.

3. Image / speech / character recognition

This of course. What do you think is the intelligence behind Siri if not data science? How does Facebook recognize your friends if you upload a photo with them? This isn’t magic; That’s data science.

4. Gaming

EA Sports, Sony, Nintendo, Zynga, and other giants in this field have set goals to take your gaming experience to a new level. To be able to upgrade to higher levels, games are developed and refined using machine learning algorithms so that they can be upgraded as you advance to higher levels.

5. Price comparison website

This website is operated with data. The more, the more fun they are. The data is extracted from the respective website via API. PriceGrabber, PriceRunner, Junglee, Shopzilla are some of such websites.

Benefits of data science

The field of science has many advantages. Here are some of the benefits of science:

Data science is fun

Data science is a rare field where you can collaborate on many things like math, coding, research, analysis, etc. If you want to do all of this, it can be a lot of fun work that will never be boring. The only catch, however, is that a developing field requires hard work, study, and no study because anytime in this area the simplest solution to the problem turns out to be good.

Lots of job titles

Due to demand, there are many career opportunities in various fields. Some of them are data scientists, data analysts, research analysts, business analysts, analytics managers, big data engineers, and others.

There is an urgent need for data scientists in the market as there is a significant difference between the demand and skills of data scientists. LinkedIn reports reveal that data scientists are the most promising jobs in America in 2019. It is one of the fastest-growing jobs posted in December 2019. This is the average annual growth rate for data scientist jobs since 2015. is 37% and the industry’s best in this role are information technology and services, financial services, the internet, and computer software. According to the IBM report, the demand for data scientists will increase by 28% in 2020.

Customize products

Data Science helps companies customize their products by better understanding users’ needs to tailor user experience. Businesses can also increase sales and increase sales because data science helps companies decide when and where their products will sell best.

High paying career

As data scientist continues to be the sexiest job, the salary for this position is also high. According to a study on dice salaries, the average annual salary of a data scientist is $ 106,000 per year.

Cost optimization

With the help of data science, costs for companies are optimized very efficiently. It can also help increase individual productivity and use of resources.

AI is the future

When we talk about technology, the world is moving at a good speed. With AI, we try to make machines as smart as humans. AI uses data science to find solutions to complex problems by extracting insights from data. Some of the AI ​​achievements that could have a positive impact on the future are transportation automation (eg driverless cars). Robots play an important role in a very dangerous job.

Disadvantages of data science

Anything that has a lot of advantages has a few disadvantages too. So let’s take a look at some of the drawbacks of data science:

Data security

Data is a key component that can increase the productivity and income of the industry by making game-changing business decisions. However, the information or findings obtained from the data are misused against organizations, groups of people, commissions, etc.


The tools and techniques used for data science can sometimes be costly because some tools are very complex and require expertise or training to use them. It is also very difficult to choose the right tool according to the circumstances because the choice is based on the correct knowledge of the tool and its accuracy in analyzing data and in retrieving information.

The term is misleading

As a data scientist, usually, everyone will think of someone scientifically involved with data, but that’s not the case. Data science is separated from business than science. The term data science can also include data analysis, data preparation, data management, and the like. The term data scientist can be better understood as “statistical inference”, that is, collecting data using statistics.

It doesn’t allow experimentation

The data science field uses many different skills to process data and develops data-driven solutions for businesses. Data scientists need to know a variety of skills such as programming, machine learning, statistics, business strategy, etc., but data science does not allow them to study any particular field.
