8 benefits of using big data for businesses

1. Better customer insight

Businesses can use the following data sources in big data systems to better understand their customers, both individually and in groups:

• Website behavior logs.
• Mobile app interactions.
• Purchase histories and customer interaction data.
• Social media activity.
• Internal and external survey results.
• Financial records and credit reports.

Clickstream analysis of e-commerce activity is especially useful in an increasingly digital marketplace. It shows how customers navigate through webpages and menus. In addition to tracking product purchases, companies can see which items shoppers remove from their carts or transactions they abandon. This provides valuable clues on what customers are interested in, even if they don't buy the products at that time.

Big data analytics also helps retailers track customer behavior in brick-and-mortar locations. Analyzing in-store videos shows how shoppers navigate through stores and where they spend the most time, enabling companies to optimize layouts and product placement.

2. Increased market intelligence

Big data helps businesses gain a deeper understanding not only of their own customers, but also of market trends and dynamics. The market intelligence generated by big data applications informs competitive analysis, product development and marketing strategies. For example, a company can prioritize specific product features to match consumer preferences.

Social media data is a key source of market intelligence. People share their experiences with all types of products and services on social networks. It's invaluable information for marketers tracking and analyzing trends in their industry. Other useful data sources include surveys, focus groups, industry reports and rival websites.

3. Agile supply chain management

Wars, expanded tariffs, the COVID-19 pandemic and other global events have made it clear that modern supply chains are complex and distressingly fragile. But big data enables predictive analytics, often in near real time, to help businesses avoid major disruptions and keep their supply chains working smoothly.

Big data systems integrate sales, customer demand and production planning data with real-time inventory and pricing data from suppliers, as well as external shipping and weather data in some organizations. All this information provides a level of detail not previously available, supporting more agile supply chain management processes.

It's not just large enterprises with global supply chain networks that benefit from these insights. Smaller companies can also use them to optimize supply chain decisions and reduce related business risks.

4. Improved business operations

Big data applications improve a wide range of business activities, including the following:

• Optimized business processes that lower costs, boost productivity and increase customer satisfaction.
• More effective hiring and workforce management.
• Better fraud detection, risk management and cybersecurity planning to help reduce financial losses and avoid potential business threats.

Companies can also optimize predictive maintenance on critical equipment and systems, reducing costly repairs and downtime. At a basic level, this involves analyzing sensor data, service records and warranties. However, the use of manufacturing machines and HVAC systems is affected by production and staffing schedules, which are influenced by sales cycles, customer behavior and supply chain logistics. Well-designed big data systems integrate all this information for analysis.

5. Data-driven innovation

Innovation doesn't just require inspiration. It takes a lot of hard work to identify promising new business initiatives, conduct proof-of-concept experiments and put validated ideas into production. Organizations can use various big data tools and technologies to analyze opportunities and drive R&D efforts, boosting the development of new products and services.

Organizations have typically deployed separate systems for different analytics purposes. Traditional data warehouses support structured BI querying, while data lakes store raw unstructured data for machine learning and other data science applications. Now, a unified architecture combining elements of those two platforms is available: the data lakehouse. A data lakehouse stores both structured and unstructured data; it's flexible and scalable like data lakes, while providing the data integrity and query performance of data warehouses.

This consolidation accelerates business innovation in practical ways. When data scientists, other analysts and business domain experts can access the full breadth of an organization's data in a single, well-governed platform, they can more easily identify data patterns and investigate hypotheses as part of innovation efforts than in a fragmented environment.

6. More effective AI models and agents

Enterprise AI applications now extend well beyond chatbots and content generation. Notably, companies are increasingly deploying agentic AI systems that operate autonomously in analytics and business workflows. AI agents make decisions, take actions and coordinate with other agents. Big data platforms provide both the training data for these systems and the operational infrastructure on which they run.

Big data also empowers businesses to continuously update and refine AI models. For example, by collecting and analyzing data on how users interact with generative AI applications, companies can pinpoint areas for improvement, fine-tune the models that underpin the applications and create a more engaging UX.

7. Support for real-time data streaming and event-driven decisions

Traditional analytics is based on batch processing. Data processing often happens overnight, so refreshed reports and dashboards are ready the next morning. In other cases, data is updated weekly or monthly. However, such cadences don't match the pace of business in many companies. Streaming data platforms process events as they occur, enabling users to detect business opportunities and issues in real time and respond to them immediately.

Big data is at the heart of real-time analytics applications in industries such as logistics, retail, financial services and manufacturing. These applications depend on architectures designed for continuous data flows, with message queues, stream processing systems and event-driven microservices. The streaming infrastructure can also connect to a data lakehouse. Doing so provides both the immediacy of real-time responses and historical context that helps ensure they're effective.

8. Smarter recommendation engines

Recommendation engines have evolved significantly since the advent of big data systems. Initially, predictive analytics in recommendation engines was quite simple: Association rules found common items in online shopping carts. Though that's still a common website feature, newer recommendation systems driven by big data are much smarter.

They build on the sophisticated customer insights generated by big data applications, making them more attuned to customer behavior and demographics. These engines aren't limited to e-commerce, either. A waiter's dinner recommendations might be data-driven, prompted by a restaurant chain's point-of-sale system evaluating inventory levels, popular meal combos, high-profit items and social media trends.

Streaming content providers use even more sophisticated techniques. They might not bother asking what customers want to watch next. When a movie, TV program or video finishes, the recommended next selection often begins immediately. It's a practice aimed at keeping viewers engaged by combining their preferences with broader big data analytics results.
