Sarah El Shatby Published on 1 Jun 2022 10 min read

Today, organizations increasingly rely on information gathering and insights to further their business growth, make strategic business decisions, and bring in a wider set of audiences. In other words, they need data. But where does it come from? It might seem like the term data science became trendy in the last decade. However, the history of data is much longer than that. In fact, it has been around much longer than we think. Despite being different from what we know now, data did exist. People have been using it for centuries, working hard to innovate new ways to benefit from it.

In this explorative article, we’ll take a time machine back to 19,000 BC when the first evidence of data collection was found. Next, we’ll fast-forward to the 1600s and the first known concept of data. Then, we’ll visit the 1800s and 1900s to track how data evolved over time to provide different services and solutions. Back to the future, we’ll briefly touch upon the modern-day applications of data analysis and data science, and what role they play in the different industries.

What is Data?

The word “data” derives from the Latin word “datum” (singular), which means the “thing given”. If you look at the Merriam-Webster definition, you might find it easier to understand the meaning.

Technically speaking, data is any information that has been translated into different forms to be processed, analyzed, managed, and transferred. The word itself is an enormous umbrella term for many concepts and scientific branches, such as statistics and mathematics. There are different data types according to their classification; information can be numerical and textual, or even in audio, video, and image form. The scope is big and continues to evolve as our environment changes around us.

The History of Data Timeline

The history of data, dating from 19,000BC to the 1990s and beyond.

While data is all around us, it’s important to understand where it comes from. What were its origins and how did it come to be as we know it now?

We might not have access to a working time machine like the Doctor’s Tardis, but we can still take a trip along the data timeline. Allons-y!

History of Data in 19,000 BC: The Great Baboon

The first use of data goes back to 19,000 BC when our Palaeolithic ancestors used a baboon tool called the Ishango bone to perform simple calculations. Back then, there were no calculators, pens, or even paper – as we know, those came much later. Thus, we consider this prehistoric invention as the first evidence of tallying or recording information.

History of Data in the 1640s: The Father of Public Health Statistics

In the 1640s, John Graunt, a hat maker, started collecting information regarding deaths in London. He noted down statistics such as:

  • The number of deaths
  • The mortality rate among age groups
  • The causes of death

In this way, he revolutionized how we use medical data to this day. In fact, Graunt was the first person to use data analysis to understand and solve a problem.

In 1665, he published his book, Natural and Political Observations Mentioned in a Following Index, and made upon the Bills of Mortality, as the collective result of his research. In it, the innovator stored information in tables and even attempted to predict life expectancy.

As a result of Graunt’s publication, the city started issuing a weekly report called “Bills of Mortality”. Knowing the number of deaths and births better prepared people for a possible plague outbreak.

History of Data in the 1880s: The Era of Data Processing

One day back in the 1880s, the German-American statistician Herman Hollerith saw a train conductor punching train tickets for passengers. That’s how the idea of using punch cards in writing and processing data was born. Hollerith started working on the design of the tabulation machine that uses punch cards, based on a previous model invented by the silk weaver Joseph Jacquard in the 1800s.

A punch card is normally a type of stiff paper, onto which a machine would create holes in specific locations. The cards are moved between brass rods so that the data is read electronically. With this great breakthrough, Hollerith helped the American government complete the US census within the same year – after it took them nearly a decade of trial and error.

History of Data in 1928: The Concept of Storage

Pfleumer’s Magnetic Tape

In 1928, the German engineer Fritz Pfleumer patented a magnetic tape that he used to replace wire recording for storing data. Essentially, he coated very thin paper with iron oxide powder and glued it with lacquer. The idea of storing information on magnetic tapes actually inspired the invention of floppy disks and hard-disk drives later on.

Codd’s Relational Model

The computer scientist Edgar Codd was the first one to introduce the idea of a relational database management system, which we know today as a “data table”.

In the 1960s, he started working on a model that can describe data attributes in columns and their values in rows:

History of Data: Edgar Codd’s relational database model otherwise known as a data table.

Structurally speaking, each column has a header with the attribute or feature name, while the rows are full of values. Meanwhile, the entire table is named after the content within it.

Present-Day History of Data: The Internet Era

With the rise of the internet consequently comes the rise of big data. Thanks to Sir Tim Berners Lee, hypertext and hyperlinks made it easy to share information and connect resources.

And with the introduction of Google in 1997, data became even more widely available to everyone with access to a computer or mobile device.

While this is the last stop in our time-traveling journey today, it’s certainly not the final destination on the history of data timeline. With every innovation in technology, data science, machine learning, or AI comes a new way of creating and spreading information.

Data has changed the way we look at the world and continues to shape it in different ways. Nowadays, industries like finance, astronomy, and many more, benefit from employing analytical techniques to improve their operations.

Understanding Data Analysis

Now that we’ve gone through the history of big data, it’s time to learn how to use it to its fullest potential today. As a starting point, we’re going to cover data analysis. The term, as defined by the Cambridge Dictionary, is “the process of examining information, especially using a computer, in order to find something out, or to help with decision making”.

In our context, data analysis is the full process of collecting, exploring, preprocessing, and analyzing data in order to draw insights that can be used by companies in almost every industry, from commerce to healthcare and transportation.

How to Conduct Data Analysis?

Step 1: Identify the Objective

The first step for any task is to question why it’s necessary in the first place. Why do you need to do this analysis? Perhaps you need to find which of your company’s products has sold the most, or why a specific production line has the biggest losses. You might even want to find out why a hospital’s patients spend too much time in the waiting room. The important thing is to have a clear objective in mind before you begin.

Step 2: Collect the Necessary Information

Now it’s time to gather your samples. There are multiple ways to collect data according to the analysis purpose. Based on the industry and available time to solve the problem, collection methods include but are not limited to:

  • Surveys and questionnaires
  • Online tracking
  • Online and offline interviews
  • Documents and historical records

Step 3: Clean the Data

It’s widely known in the data community that professionals spend 80 to 90% of their time cleaning data before analyzing it. Since the real world is rather messy and disorganized, you must get your hands dirty first.

This step can be broken into a few smaller ones, including:

  • Inspecting the integrity and structure of your data
  • Searching for outliers
  • Checking for missing and duplicate values

Step 4: Start the Analysis

After cleaning, comes a quite significant step – the actual analysis process. This can be done in several ways depending on the purpose and data type, including but not limited to:

Each type serves a different purpose. You need to know beforehand which analysis method will be best suited for the results you want to obtain.

Step 5: Communicate the Findings

Now, the most important step is to communicate your findings, which eventually explain the answer to your question.

In this step, it’s critical to keep everything neat and simple. The best way to achieve this is through a dashboard of visualizations and a summary report that illustrates the insights drawn from the analysis step.

Understanding Data Science

According to IMB, “data science combines the scientific method, math, statistics, specialized programming, advanced analytics, AI, and even storytelling to uncover and explain the business insights hidden in data.”

This explains why studying it takes a much longer time than studying data analysis. The reason for this is that the latter is considered a phase in the data science process. To be a successful data scientist, you need to understand analysis first. On top of that, you have to have basic knowledge of programming, statistics, and machine learning.

Real-life Data Use Cases

There are countless applications of data in real life. As we’ve already mentioned, any industry that comes into your mind in fact employs different techniques within the organizational workflow.

Two decades ago, people were unfamiliar with the concept of data even though it has been used for a really long time in different ways. Today, we’re much more aware and know how to manipulate it to extract meaningful insights.

In this part of the article, we’ll delve into some real-life applications of data that many companies rely on to leverage their potential and improve results.

Web Traffic Forecasting

Five years ago, Google hosted a competition on Kaggle to predict future values of web traffic to help improve the infrastructure and solve issues like sudden outages. They offered a $25,000 prize to the user with the best predictive model. More than 1000 participating teams had to work on a set of 145,000 Wikipedia articles.

To do a similar project, you must first understand time series analysis. To get started, you can check out 365 Data Science’s Time Series Analysis with Python course. And while the prize is no longer up for grabs, you still can head over to the competition page on Kaggle and practice your newfound skills.

Fake News Detection

Data scientist Johnny Wales built an AI tool that can analyze a news article’s URL to predict whether the information is real or fake based on the words written in the article. He added the tool to the Unslanted website so that anyone can use it.

Amazon’s Use of Big Data

While we know Amazon as a multinational American company founded by Jeff Bezos in 1994, its humble origins started as a marketplace for books. Later, it expanded to offer the wide variety of categories we see now. Millions of customers purchase items from the website every day. How did they succeed in such a global outreach? Well, the company is a perfect case study of how data is used to transform businesses.

Amazon uses the power of big data and business analytics to analyze consumer behavior. Having millions of users from all over the world enables the data teams to sort through vast amounts of information, including:

  • Purchase preferences
  • Browsing habits
  • Demographics

Using data science, they can easily carry out customer segmentation and tailor their marketing approaches to reach their target clusters.
