What is Big Data?

It’s hard to believe, but up until 2000, only 25% of the world’s stored information was digital. Today, that figure is 99.9% — a staggering increase, and a transformative shift in how we define “information”.

And by information, we mean data.

Now consider the vast amount of information that you create or encounter on a daily basis. It’s all digital, and it’s all data: everything from sales and marketing reports, to quarterly forecasts and customer history, to image and audio files. Your customers (and prospects) are creating data, too. Every click, “like,” purchase, download, and interaction with your brand produces data that can be used to understand your customers behavior, and build better customer experiences. This creates a huge volume of different kinds of data that all need to be stored, analyzed, and actioned.

Welcome to the world of big data.

Big data refers to large, diverse datasets that are so complex that they can’t be managed using traditional data processing methods. Imagine all the interactions, clicks, likes, downloads, and purchases mentioned above, generated daily, on a global scale.

And big data is only getting bigger. In fact, over two-thirds of analytics and IT leaders expect data volumes to increase 22% on average over the next year. As data volumes continue to grow, so do the opportunities to use big data to drive even more business value, and provide the foundation for powerful AI solutions.

Learning the basics of big data is critical for everyone who needs to understand how data and AI can be used to solve business challenges. Whether you’re a data analyst or a business leader, this article will help you get started.

A helpful way to think about big data is to consider its three characteristics: volume, velocity, and variety (known as the “three Vs”).

Volume refers to the sheer amount of data being generated and collected. Online retailers, for example, generate vast amounts of data, ranging from transaction history and website interactions to inventory management and customer service systems.

Velocity refers to the speed at which data is being generated and processed. In the world of finance, stock exchanges process high-velocity data streams to make split-second trading decisions based on real-time market data. Banks and credit card companies analyze transaction data in real-time to identify and prevent fraudulent activities.

Variety refers to the different types and formats of data. For healthcare providers, this can include everything from patient demographics and medical history to lab results, imaging data, and clinical notes.

According to our latest State of Data and Analytics Report, 80% of business leaders say data is critical in decision-making at their organization. But to translate data into actionable insights, you need data analytics. Data analytics refers to the tools and processes that allow you to extract valuable insights from all of this data and make better decisions.

For example, businesses can analyze historical and real-time big datasets to identify trends, patterns, and correlations, and make more confident decisions based on the data. A data-driven approach replaces intuition and guesswork, and also supports more accurate and effective business strategies.

Ninety-four percent of business leaders feel their organization should be getting more value from their data. One way to do this is through platforms that can bring all your internal and external data together, including data from external data lakes and warehouses.

By unifying all your customer data, you can develop a 360-degree view of your customer and use AI to find actionable insights that help you make better decisions, and deliver business results.

AI, including generative artificial intelligence (GAI), relies on big data to train and improve its algorithms. And, the more diverse the data, the better AI performs .

When your data is unified on one platform, you can begin to reap the benefits:

• Analysts can view unified profiles and gain insights about your customers that can be used for personalized marketing, product innovation, better service delivery, and more.
• Developers can create applications, such as health-scoring apps, using unified data. Apps can provide critical information to health-care providers who receive real-time alerts when a patient’s score dips below a certain number.
• Your sales reps need to understand their prospects at a granular level. Are they opening emails? What are they looking at on the website? Based on all prospect data, how likely are they to buy? Unified data can help answer all of these questions.
• E-commerce managers can use data to personalize their website based on a customer’s browsing behavior and current product stock levels, ensuring a relevant and targeted customer experience.

Once you’re able to see the big picture, it’s easier to identify gaps in the market, discover new opportunities, and develop products and services that customers want and need.

The “mosaic” of big data consists of many different kinds of data. Knowing the data types listed below is the first step to understanding how to effectively manage, analyze, and extract valuable insights from your data.

This type of big data is formatted in fields that can be easily sorted and analyzed. Think spreadsheets and lists arranged in columns and rows. Examples include:

• customer information
• point-of-sale data
• inventory records
• financial data, such as transaction records.

Unstructured data includes categories of information that can’t be organized into rows and columns. Think social media posts, emails, customer reviews, and multimedia content like photos and videos. Unstructured data is nearly 80% of all data, but it hasn't always been easy to analyze. Thanks to AI and machine learning, it’s possible to gain valuable insights from this vast category of data.

This type of data has some organization but doesn't fit neatly into traditional databases. Semi-structured data often contains tags and labels (metadata) that is used to group data and describe how it is stored. Examples include XML files, JSON data, and log files.

Metadata is information that describes other data. This “data about data” provides details about the characteristics, attributes, and properties of a dataset. The metadata of a video file, for example, may include information about its duration, resolution, and encoding format.

Time-series data is used to analyze trends, patterns, and changes over a specific period. Examples include stock market prices, weather data, sensor readings from IoT devices, and website traffic data.

Geospatial data is related to specific locations. It includes coordinates, addresses, maps, and satellite imagery. Geospatial data is used in applications like GPS navigation, urban planning, and environmental monitoring.

Streaming data comes from sources like social media feeds, sensor networks, and online transactions. Analysis of streaming data provides organizations with information needed to make immediate decisions and respond to events as they happen.

In AI-driven projects, all of these data types can be used together to help your organization gain a well-rounded understanding of your customer. Unstructured data, in particular, holds enormous potential in the age of AI. By applying advanced analytics and machine learning, organizations are able to extract insights from mounds of messy information and deliver targeted customer experiences, product innovations, and more.

Now that you understand the many different types of data, you can begin to see that insights from all of these data types are necessary for gaining deep understanding of your customer, driving innovation, and making better decisions.

Your data is only valuable when it’s properly managed, protected, and available for analysis. Let’s look at a few key concepts about the data life cycle and learn how it all comes together.

How do you get from raw data to actionable insights? Your approach is guided by your data strategy. This strategy is an essential framework that guides your organization's approach to collecting, managing, and using its data. Your strategy should include defining goals, identifying data sources, and establishing processes for data acquisition, storage, and analysis. A solid data strategy aligns data initiatives with business objectives, so the entire organization is on the same page about how data should be used to support the business.

Data governance is an important part of your data strategy. Your data governance framework includes standards for data quality, integrity, and compliance for your business. A good governance framework specifies the policies, procedures, and controls for data management, access, and usage that apply to each team in the organization. Effective data governance helps ensure that data is accurate, consistent, and trustworthy — allowing organizations to make informed decisions and comply with regulatory requirements. In fact, 85% of analytics and IT leaders use data governance as a way to guarantee and validate data quality.

Security and big data are two sides of the same coin. So it’s no surprise that analytics, IT, and business leaders all cite security threats as the top barrier to successful data management. To address this, organizations need comprehensive data security measures to protect data from unauthorized access, breaches, and cyberthreats. This includes using a wide range of security solutions, from encryption and event monitoring to multifactor authentication and employee security training, to ensure the highest standards of confidentiality, integrity, and availability. Strong data security measures build trust with both customers and stakeholders, and help safeguard the organization's reputation.

Data privacy is critical in the era of big data. And safeguarding your customers’ privacy is directly tied to your business success. Organizations should ensure that they always maintain compliance with regulations regarding customer data handling. This includes obtaining consent for data collection, establishing privacy controls, protecting sensitive information and adopting security policies to safeguard sensitive data.

What can you do with big data and big data analytics? Once an organization has analyzed the information, the opportunities are as endless as the data.

Big data is informing the business strategies of some of the world’s largest companies — and delivering substantial value to customers and the bottom line. Here are just a few examples of how data, AI, and customer relationship management (CRM) are changing the game for these big brands:

Big data is powering AI algorithms, and data is required to ensure that AI-powered solutions are trained with the right sources to learn and adapt. Fashion house Gucci put AI at the center of Gucci 9, its global client service network, with Salesforce Platform. Now, AI generates bite-size conversation replies in a "Guccified" brand voice to help advisors assist customers in every interaction.

Multinational food company General Mills wanted a better way to use its data to reach consumers on a more personal level while maintaining privacy. With its wealth of purchase and behavioral data, the company zeros in on data, such as from recipe views and receipt scans, to recommend personalized content to consumers, based on their diet or geography. This helped them triple consumer engagement, increase known site users 170% year over year, and save millions of dollars in paid media.

Specialty retailer Williams-Sonoma Inc. uses data from past purchases to customize the emails and ads it sends to customers, which has tripled engagement. Using Data Cloud, an advanced data platform, the company creates a 360-degree view of each customer and segments the data into niche audiences. “Personalization is table stakes,” said Abby Teisch, SVP of Marketing. “We not only want to show you the product, we want to tell you how to use it, how to cook with it, and what it’ll look like in your home.”
