From water systems and hospitals to public transport and public relations management, the growth in the volume and importance of data plays a critical role in today's world. Data has long determined the success of businesses, but now it has also come to be a vital element in the smooth running of social, commercial, and government infrastructures.
The IDC predicts that global data volume will grow to 163 zettabytes (or a trillion gigabytes) by 2025. This is ten times more than in 2016 when 16.1 zettabytes of data were generated in 12 months. All this data will open up unique experiences for ordinary users and new opportunities for commerce.
By 2025, the average person around the world will interact with devices nearly 4,800 times a day - about one contact every 18 seconds.
Now imagine that all the information created and transmitted to different systems needs to be stored somewhere and managed intelligently.
Understanding Big Data
Let's start with the definition of data science. This discipline studies the challenges of processing, analyzing, and presenting data in the digital age. The term was coined by Peter Naur, author of 'A Basic Principle of Data Science'. It was in the early 1980s when data became increasingly digital, leading to the development of a new era.
In the past, the increasing amount of data might have been held by just a few big players in the market, or by the government. But after 2007, with the advent of the iPhone, the rise of Google, the advent of Hadoop, and other technologies, coupled with cheaper ways of handling data, the world faced incredible amounts of data.
Undeniably big data streams are called Big Data, thanks to Clifford Lynch, editor of the journal 'Nature'. Yes, this amount of information has existed before, but it has become more prominent nowadays.
Today, big data has several characteristics:
- Volume. Starting at 150GB per day.
- Speed. The speed at which data arrays are accumulated and processed is regular, requiring real-time processing.
- Variety. Big data can be diverse: structured, unstructured, or mixed.
- Veracity. Not only the data itself but also the results of data analysis must be trustworthy.
- Variability. Variability in data can occur due to various factors, making it difficult to analyze.
- Value. Each particular dataset has its own value and complexity.
Big Data Methods and Technologies
Big data require different processing than traditional data. The following methods stand out:
Descriptive analytics uses mathematical functions, and current and 'historical' data analysis results answer questions about what has happened in real-time. The simplest example is a year's revenue data collected in Google Analytics.
Predictive analytics appears to be a way of predicting the possible outcomes of events based on previously collected and analyzed data. In the stock market, for example, predictions are made about the rise or fall of a company's share price.
Prescriptive analytics is similar to predictive analytics in that it can also show possible future scenarios. This allows business owners to see the weaknesses of the project and learn how to avoid them in the future.
Diagnostic analytics analyzes large amounts of data to answer why something has happened. It identifies anomalies or connections between events or other variables.
The tools and technologies required for data analysis also differ from the traditional ones and include data mining (extracting previously unknown data from other datasets), specialized software, neural networks, artificial intelligence, machine learning, visualization of complex data, etc.
