Big Data – what it is, its essence, how it works and why it is needed. Definition & meaning.

Big Data is a term that describes huge amounts of data that are collected, stored, and analyzed in order to obtain useful information and discover new knowledge.

 

What is BIG DATA – concept and definition in simple words.

 

In simple terms, Big Data is simply a large amount of information that is collected from various sources and processed using special tools.

Imagine a huge library with thousands of books, where each page contains some data. Big Data is like a whole library that we analyze to find important knowledge and answers to questions.

The main features of Big Data can be compared to the three Vs: Volume, Variety, and Velocity. Volume is the amount of information collected, variety is the different types of data, and velocity is how fast we can collect and process this data.

Big Data is used in many industries, such as medicine, finance, marketing, and others, to better understand the situation, identify dependencies, and support decision-making. Thanks to Big Data, we can open up new opportunities and improve the quality of our lives.

 

 

Pioneers in the use of Big Data.

Big Data was first applied in some well-known projects that showed the potential of this technology and changed the direction of development of various industries.

The SETI@home project: The Search for Intelligent Life in the Universe.

One of the earliest examples of Big Data usage is the SETI@home project, launched in 1999. Its goal was to analyze huge volumes of radio signals from space to detect possible traces of intelligent life. As part of this project, the data was distributed among hundreds of thousands of computers from private users, which became the prototype of modern cloud solutions for Big Data processing.

Research of the human genome: A revolution in genetics.

In the 2000s, a well-known event in science took place – the human genome decoding project. It required the analysis and storage of a huge amount of genetic information. Thanks to the use of Big Data, databases of genetic sequences were created, which became the basis for numerous scientific studies and the development of personalized medicine.

Google: Innovations in search technology.

Google, the world leader in search engines, has also been using Big Data since its founding in 1998. Thanks to the analysis of huge amounts of information from the Internet, Google was able to improve its search algorithms and create various services such as Google Maps, Google Analytics, and Google Ads, which revolutionized the world of digital marketing, advertising, and analytics.

Netflix: Personalization of recommendations in streaming services.

The video streaming service Netflix has become another pioneer in the use of Big Data. They started analyzing large amounts of data about their users and their viewing habits back in the 2000s. The application of machine learning algorithms allowed Netflix to create personalized recommendations for each user, increasing service satisfaction and ensuring audience loyalty.

These and other early use cases of Big Data inspired other companies and organizations to explore the possibilities of this technology. Over time, Big Data has become a key tool for analyzing data in many industries, from healthcare to finance, and continues to open new horizons in the development of the modern world.

 

 

The origin and popularity of the term Big Data.

To understand how the name “Big Data” came to be and how it has gained popularity in the tech world, let’s dive into the history of this concept.

• The origin of the term Big Data. The term “Big Data” appeared in the late 1990s, but some sources claim that it originated in the 1970s. The first person to use the term was John Musgay, a computer science expert who called “big data” one of the main challenges of modern computer science.
• The term gained popularity. In the early 2000s, with the development of the Internet and the initial implementation of Big Data technologies, the term became increasingly well-known in the technical community. In 2011, an important event took place – the prominent analytical center Gartner recognized Big Data as one of the key strategic technologies, which contributed to the growth of interest in this topic.

Basic Big Data technologies and their ecosystem: Hadoop, Spark, and NoSQL databases.

Big Data uses a variety of technologies to efficiently store, process, and analyze large amounts of information. Some of the most popular technologies used in this field include Hadoop, Spark, and NoSQL databases. Let’s take a look at the role and functionality of these technologies in the process of big data processing.

Hadoop: distributed big data processing.

Hadoop is an open source software that allows you to store and process large data sets on clusters of cheap servers. It is based on the Hadoop Distributed File System (HDFS) model, which allows you to distribute data volumes between cluster nodes. The main components of Hadoop are HDFS and MapReduce, which is responsible for parallel processing of data on different cluster nodes.

Spark: high-speed data processing and analysis.

Spark is another open source big data project that is designed for high-speed, real-time data processing and analysis. It uses its own cluster manager and can also work with Hadoop or Mesos. Spark provides interfaces for various programming languages such as Scala, Java, and Python, and includes libraries for machine learning, graphical analysis, and streaming data processing.

NoSQL databases: flexibility and scalability.

NoSQL databases are a group of databases that differ from traditional relational databases in their flexibility and scalability. They allow you to store and process unstructured and semi-structured data that is common in Big Data. NoSQL databases can be of different types, including key-value, column, document, and graph databases. Famous examples of NoSQL databases include Cassandra, MongoDB, and Couchbase.

Interaction and integration of Big Data technologies.

It’s important to note that these technologies often interact and integrate to create comprehensive Big Data solutions. For example, Hadoop and Spark can work together to process and analyze big data using HDFS as the basis for data storage. NoSQL databases can be used to store and process unstructured data, which can then be analyzed using Spark or Hadoop.

Big Data ecosystem.

The Big Data ecosystem consists of various components that work together to ensure efficient storage, processing, and analysis of big data. This includes not only the aforementioned technologies, but also other tools and solutions, such as ETL tools (Extract, Transform, Load), data management systems, analytical platforms, cloud computing infrastructure and services.

In general, Hadoop, Spark, and NoSQL databases are key technologies that help organizations efficiently store and process big data. Understanding their roles and functionality will help IT professionals better utilize the potential of big data and develop effective solutions for analyzing and processing information.
