Understanding of Big Data and It's Usage

Understanding of Big Data and It's Usage

Big Data is exactly what it sounds like - a huge amount of data. It is a game-changer in the digital age, describing large volumes of structured and unstructured data that power modern organizations on a daily basis. The ability to harness, analyze, and leverage this wealth of information has transformed industries and redefined the way businesses operate.

Understanding Big Data

There's nothing new about the notion of big data, which has been around since at least 2001. The term 'Big Data' is usually refer to massive, rapidly expanding, varied, often unstructured and complex datasets of digitized data that are difficult to maintain using traditional methods. It encompasses three main dimensions:

  • Volume: The sheer amount of data generated from various sources.
  • Velocity: The speed at which data is generated and processed in real-time.
  • Variety: The diversity of data types, including structured, unstructured, and semi-structured data

We've generated lots of data by making online purchases and participating in social media and other online activities. According to Berkeley researchers, we are now producing roughly 5 quintillion bytes (or around 4.3 exabytes) of data every two days. Big data can include digitized documents, photographs, videos, audio files, tweets and other social networking posts, e-mails, text messages, phone records, search engine queries, RFID tag and barcode scans and financial transaction records.

Besides home computers and retailers' point-of-sale systems, we have Internet connected smartphones, WiFi-enabled scales that tweet our weight, fitness sensors that track and sometimes share health related data, cameras that can automatically post photos and videos online and global positioning satellite (GPS) devices that can pinpoint our location on the globe, to name a few.

Applications of Big Data

1. Business Analytics

Big Data analytics provides valuable insights for businesses, enabling better decision-making, identifying trends, and predicting customer behavior.

2. Healthcare

Big Data aids in disease prevention, patient diagnosis, personalized medicine, and health management systems.

3. Finance and Banking

It helps in fraud detection, risk analysis, algorithmic trading, and customer behavior analysis.

4. Retail and E-commerce

Big Data drives targeted marketing, inventory management, sales forecasting, and personalized customer experiences.

5. Smart Cities

Utilizing data for urban planning, traffic management, waste management, and energy optimization.

How does Big Data help to solve our day to day problems?

Big data have to be collected, managed, linked together and interpreted for any use to anyone. Companies and other entities need to filter the vast amount of available data to get what's most relevant to them. Modern hardware and software are processed, store and analyze huge amounts of information and find the best solution. Some of the softwares are becoming more intelligent so that it doesn't necessarily take a team of programmers and data scientists to wrangle the data.

Interpretation of Big Data can bring about insights which might not be immediately visible or which would be impossible to find using traditional methods. This process focuses on finding hidden threads, trends, or patterns which may be invisible to the naked eye.

Much of this big data processing and analysis is aimed at finding patterns and correlations that provide insights that can be exploited or used to make decisions. Businesses can now mine massive amounts of data for information about consumer habits, their products' popularity or more efficient ways to do business. Big data analytics can be used to target ads, products and services for the customers that are more relevant for them. Companies are now even starting to do things like sending real-time ads and coupons to people via their smartphones, when they are near to the locations where they have recently used their credit cards.

In essence, big data allows entities to use nearly real-time data to inform decisions, rather than relying mostly on old information as in the past. But this ability to see what's going on with us in the present, and even sometimes to predict our future behavior, can be a bit creepy.

Challenges and Considerations

1. Privacy and Security

Handling massive amounts of data raises concerns about privacy, data breaches, and security threats. We give more information than we realize to the companies with whom we do business, especially if we use loyalty cards or pay with credit or debit cards. Someone can learn a lot about you just from analyzing your purchases. People can tell lots about you from this data, including your age, gender, sexual orientation, marital status, income level, health status, tastes, hobbies, habits and a whole host of other things that you may or may not want to be public knowledge. They only need to have the means and the will to gather and analyze it. And whether they mean well or ill, it can have unintended consequences.

2. Data Quality

Ensuring data accuracy and reliability is crucial for meaningful insights.

3. Scalability and Infrastructure

Managing, storing, and processing large-scale data requires robust infrastructure and scalable technologies.

Tools and Technologies

  • Hadoop: A widely used open-source framework for distributed storage and processing of Big Data.
  • Apache Spark: A powerful data processing engine for faster analytics on large datasets.
  • NoSQL Databases: These databases cater to unstructured and semi-structured data, offering flexible schemas and scalability.

Future Prospects

As technology evolves, the impact of Big Data continues to grow. Emerging technologies like Artificial Intelligence (AI), Machine Learning (ML), and the Internet of Things (IoT) further augment the potential of Big Data analytics, promising new insights and opportunities across industries.


Big Data is not just about the size of data; it's about unlocking the latent value within it. Embracing Big Data analytics empowers organizations to innovate, optimize processes, and gain competitive advantages, ultimately shaping a data-driven future.
