BIG DATA AND ITS IMPORTANCE IN TODAY'S TECHNOLOGICAL LANDSCAPE

In today's digital era, data is generated at an extraordinary rate. Every click, swipe and search input produces a huge amount of data, which can be used to gain useful insights and promote business processes.?

This phenomenon is called big data, and it has transformed the way top organizations function and communicate with their customers.?

In today's article, we will be looking at the importance of big data in today's technological landscape. But before we go into that let us take some time to fully understand the concept of “Big Data”

What Is Big Data??

According to techtarget.com, big data is a combination of structured, semi-structured, and unstructured data that organizations collect, analyze, and mine for information and insight. It can be used in machine learning projects, predictive modeling and other advanced analytics applications.?

The term big data is used to classify data that is too large or complex for local databases, tools and applications to deal with.?

The innovation of new technologies such as artificial intelligence, cloud computing, machine learning, robotics etc. has made big data and important area of study and application

The term “Big Data” has been in existence since the early 1990s. Although, the earliest proof of humans storing and analyzing data can be traced back to 18,000 BCE, where paleolithic tribes people would instill notches into sticks or bones to monitor trading supplies and activities.? After this, in 2400 BCE the first device constructed for performing calculations called the abacus was invented by Ancient Mesopotamians Of Sumeria, which was made by sliding counters along rods or grooves? used to perform mathematical processes.?

In 1937, the first major data protection was established after the social security system act became law, and IBM developed a punched card- reading machine to keep? off contributions.?

It was in 1998 during the IEEE 8th conference on visualization that John Mashey, Chief scientist at SGI, presented a paper titled “Big Data”.... and the wave of infrastress. He got the credit for coming up with the term.?

Since the beginning of the 21st century, the speed at which data is generated has drastically transformed.?

According to data framework.org, the total amount of data in the world was 4.4 zettabytes in 2013, which was estimated to rise to 44 zettabytes by 2020. To make it more simple 44 zettabytes are equal to 44 trillion gigabytes. Even with the modern technologies of today's world it seems very impossible to analyze all this data. The demand to process these increasingly large data is how traditional analysis transformed into Big Data in the last decade.?

The international business management (IBM) established four characteristics of big data, and they are:?

1. Volume: Big Data is vast and is measured high in terabytes or extra bytes.?
2. Variety: Big Data comes in different formats, such as text, images, audio, and video.?
3. Velocity: Big Data is generated at a very high speed in real time?
4. Veracity: Big Data is accurate and reliable.?

Big Data Analytics

Big data analytics is the process of uncovering trends, patterns and correlations in huge amounts of raw data to assist in making data- informed decisions. These processes make use of familiar statistical analysis techniques like clustering and regression and apply them to more extensive datasets with the help of newer tools.?

Types Of Big Data Analytics

1.Descriptive Analytics: This analyzes historical data to understand past events which can be related to the present.?

2.Predictive Analytics: This helps in predicting future events based on historical or past data.?

3. Prescriptive Analytics: This helps in providing recommendations for future actions.?

Processes Of Big Data Analytics

1.Collect Data: The collection of data seems different for every organization with the innovation and efficiency of modern technology, organizations can gather both structured and unstructured data from several sources, from cloud storage to mobile applications to in-store IoT sensors and beyond

2. Process Data: Once data is collected and stored, it must be organized properly to get accurate results on analytical queries, especially when it’s large and unstructured. Available data is growing exponentially, making data processing a challenge for organizations. One processing option is batch processing, which looks at large data blocks over time. Batch processing is useful when there is a longer turnaround time between collecting and analyzing data. Stream processing looks at small batches of data at once, shortening the delay time between collection and analysis for quicker decision-making. Stream processing is more complex and often more expensive.

3. Clean Data: Data big or small requires scrubbing to improve data quality and get stronger results; all data must be formatted correctly, and any duplicative or irrelevant data must be eliminated or accounted for. Dirty data can obscure and mislead, creating flawed insights.

4. Analyze Data: Getting big data into a usable state takes time. Once it’s ready, advanced analytics processes can turn big data into big insights. Some of these big data analysis methods include:

Data mining sorts through large datasets to identify patterns and relationships by identifying anomalies and creating data clusters.

Predictive analytics uses an organization’s historical data to make predictions about the future, identifying upcoming risks and opportunities.

Deep learning imitates human learning patterns by using artificial intelligence and machine learning to layer algorithms and find patterns in the most complex and abstract data. (Source: tableau.com)?

Sources Of Big Data?

Big data can be gotten from many sources including transaction processing systems, customer databases, documents, emails, medical records, Internet clickstream logs, mobile apps and social networks.?

It can also be obtained from machine generated data, such as network and server log files, and sensor data from manufacturing machines, industrial equipment and Internet of things (IoT) devices. (Source: Tech target.com)
