How Big Data is Revolutionizing Industries: Healthcare, Finance, and E-commerce?

In the 21st century, data is the new oil and the most wanted resource, most powerful strategic asset and arguably the unseen force that is changing industries all over the world. Welcome to the Big Data era, an explosion of information defined by the three ‘V’s – Volume (the amount of data), Velocity (the speed of generation and processing), and Variety (in the form of text, images or real-time readings from sensors).

Collecting, storing, processing and analyzing this enormous flowing river of data through Artificial Intelligence (AI) and Machine Learning (ML) is not just a competitive advantage in your market; it will become a requirement for existence. The most remarkable transformation has taken place in three key areas: Healthcare, Finance and E-Commerce.

The evidence in this article will demonstrate how Big Data is transforming each of these areas through new levels of efficiency, personalization and security and why you must complete a rigorous training program in a dedicated Big Data Course to fully partake in this transformation.

1. Healthcare: From Reactive Treatment to Predictive Health

The healthcare sector has long been labeled soloed data, complex bureaucracy, and reactive treatment protocols. Big Data knows no boundaries, and is clearing a path toward proactive, preventative, and customizable care models. Data sources for ground-breaking work in health applications can widely range from Electronic Health Records (EHRs) and genomic sequencing results, to medical imaging, clinical trials, and real-time metrics from wearable technology, just to name a few. The Big Data market for healthcare will continue to grow rapidly, reiterating the critical role of Big Data in the future of medicine.

Personalized Medicine and Genomics

The most exhilarating use of Big Data in medicine is in the rise of personalized medicine. Algorithms can predict how an individual will respond to specific drugs, medication therapy, lifestyle changes, and lifestyle habits, by collecting a patient’s genomic data unique to them along with clinical background, lifestyles, and environmental data.

• Drug Development: Leveraging Big Data, researchers have the opportunity to examine large datasets of compounds and genetics, enabling the rapid identification of new drug candidates which can significantly decrease the time and costs associated with traditional drug discovery.
• Precision Treatment: With chronic diseases and cancers, AI-enabled technologies can analyze the genetic information of a patient’s tumour as well as genetic information from the patient to determine the best treatment options for that patient with the fewest side effects, rather than using a generic ‘one-size-fits-all’ treatment.

Predictive Analytics for Disease Prevention

Big Data allows organizations in the health domain to leverage health data to go beyond merely documenting health information to predicting health outcomes. Predictive models take advantage of past information and trends about the health of groups of patients to spotlight individuals at high risk for chronic conditions such as diabetes and heart disease.

• Proactive Intervention: Workers can then take the information and intervene earlier, encouraging individuals to begin monitoring their weight or even exercise or begin treatment before the chronic disease occurs. This strategy leads to improved health outcomes and, in the long run, can mitigate the severity of care and costs.
• Population Health Management: Public health officials can aggregate datasets of health-related information to identify neighbourhoods with burdens of health status; forecast seasonal flu transmission; and even track emergence and spread of infectious disease in real-time. When public health events take place these models will be helpful and make more efficient use of finite public health resources.

2. Finance: Fortress Security and Algorithmic Intelligence

The financial services sector which includes banking, insurance, and investment, generates and processes some of the largest volumes of transactional data in the world. For the finance sector, Big Data is at the heart of risk management, security, and agility to markets.

Real-Time Fraud Detection and AML

Perhaps the most important role Big Data plays in the finance space is in fighting financial crime. Banks and payment processors consume huge volumes of real-time transaction data to identify potentially fraudulent transactions. Machine Learning models can be built off billions of legitimate transactions to develop an individual ‘normal’ behaviour profile for each customer.

• Anomaly Detection: Should a transaction not conform to expectations, for example a large purchase instantly followed by an international transfer, the system will either flag the transaction for subsequent review or block it altogether within a few seconds. Real-time anomaly detection is critical for identifying more complex schemes such as anti-money laundering compliance (AML) and credit card fraud for a level of security that a human monitoring system simply cannot match.

Algorithmic Trading and Credit Scoring

On the investment front, Big Data leads to algorithmic and high-frequency trading. Advanced systems continuously input and analyze everything from market data to news stories, social media sentiment, and economic indicators to automatically execute trades for investors. These algorithms find and execute trades within milliseconds and help drive efficiency and volatility into the markets.

On the lending side, Big Data is revolutionizing credit scoring and underwriting. Financial institutions are moving beyond FICO scores, to include a vast, rich dataset of information payment history, behaviour online, and professional networking profiles, for example. This allows:

• Improved Risk Assessment: More accurate prediction of loan default risk.
• Financial Inclusion: Providing more equitable access to credit for thin-file or marginalized populations.

Hyper-Personalization in Banking

The customer experience defines modern banking. By analyzing each interaction customers have with the banks whether through mobile, online, or in-branch Big Data analytics gives financial institutions a 360-degree view of every customer. The complete customer profile allows banks to create personalized banking solutions, for example:

• Tailored Products: An issuing a specialized savings account or specific mortgage rate at the time a customer expresses intent to purchase a home.
• Churn Reduction: Predicting the likelihood that a customer may leave and proactively reaching out to them with tailored offers to improve their loyalty.

3. E-commerce: The Age of Personalized Shopping

The retail and ecommerce market is a nonstop battle for consumer mindshare. Big Data drives the competitive advantage, allowing businesses to create a shopping experience so personalized and seamless that it seems to flow seamlessly, as intended. Ecommerce leaders analyze clickstreams, search queries, purchase histories, product reviews, and product availability in a continuous feedback loop.

Dynamic Pricing and Optimized Logistics

The price you see on the website is often not the same price someone else sees, referred to as dynamic pricing. Ecommerce platforms utilizes Big Data to determine to change product prices, in real-time with a complex algorithm that takes into account:

• Competitor Pricing: Ensuring the site remains competitive.
• Inventory Levels: Lowering prices to clear excess stock.
• Customer Demand: Raising prices for items with rapidly increasing search volume.

Big Data serves as the backbone of contemporary logistics and supply chain management. Predictive demand forecasting reviews prior sales, degree of seasonality, social media trends, and even local weather conditions to determine with accuracy what products will be needed, where it should be warehoused and the minimum shipping time and costs. Achieving this level of operational efficiency is made possible specifically because the data has been mastered.

Hyper-Personalized Recommendations and Experience

A recommendation engine represents the basis for the contemporary online shopping experience. Algorithms use collaborative filtering and other sophisticated techniques to provide highly accurate product recommendations, which is a level of hyper-personalization that goes beyond simple product recommendations:

• Website Layouts: The site’s content and navigation can shift based on your inferred preferences.
• Targeted Marketing: Analyzing purchasing data helps segment customers for laser-focused marketing campaigns, ensuring customers receive promotions that are highly relevant to their interests.

Big Data is used to similarly optimize sites. E-commerce teams engage in A/B testing to optimize website design, button placement, checkout flow, etc., through continuous analysis of user clickstreams and behaviors, etc. They are constantly identifying and removing user friction points to maximize conversion rates.

Final Thoughts: Securing Your Future with a Big Data Course

It is beyond dispute that Big Data is driving the transformation of industries in countries across the globe. It provides for precision healing, secures financial systems, and predicts consumer intentions.

For each of these three industries that I have mentioned (hospital networks, the surge of FinTech-startups, and global ecommerce), this technology-boosted data revolution has caused a huge skills gap. Companies are clamouring to find people who can traverse from raw data to business value. This has included positions like Data Scientist, Data Engineer, and Business Intelligence Analyst, which remain some of the most coveted and highly paid jobs in the world.

If you want to position yourself further in your area of practice to be able to withstand the future, you would find that a course dedicated to Big Data will at the very least provide you with a toolkit that will include fluency in statistical modeling, understanding and use of data processing platforms (like Hadoop, Spark), programming in languages like Python and R, and basic understanding of machine learning concepts.

Participating in a Big Data Course is not merely about acquiring a technical skill, but also about securing a passport into the future of industry. It allows you to become the PageMaker who will take the overwhelming, untamed stream of data and create the thoughtful, strategic decisions to lead the next generation of healthcare, finance, and e-commerce. The data-driven future is present, and the need for someone to lead it has never been greater.
