What is big data analytics?

Big data analytics examines and analyzes large and complex data sets known as “big data.”

Through this analysis, you can uncover valuable insights, patterns, and trends to make more informed decisions. It uses several techniques, tools, and technologies to process, manage, and examine meaningful information from massive datasets.

We typically apply big data analytics when data is too large or complicated for traditional data processing methods to handle efficiently. The more information there is, the greater the need for diverse analytical approaches, quicker handling times, and a more extensive data capacity.

How does big data analytics work?

Big data analytics combines several stages and processes to extract insights.

Here’s a quick overview of what this could look like:

  1. Data collection: Gather data from various sources, such as surveys, social media, websites, databases, and transaction records. This data can be structured, unstructured, or semi-structured.
  2. Data storage: Store data in distributed systems or cloud-based solutions. These types of storage can handle a large volume of data and provide fault tolerance.
  3. Data preprocessing: It’s best to clean and preprocess the raw data before performing analysis. This process could involve handling missing values, standardizing formats, addressing outliers, and structuring the data into a more suitable format.
  4. Data integration: Data usually comes from various sources in different formats. Data integration combines the data into a unified format.
  5. Data processing: Most organizations benefit from using distributed frameworks to process big data. These break down the tasks into smaller chunks and distribute them across multiple machines for parallel processing.
  6. Data analysis techniques: Depending on the goal of the analysis, you’ll likely apply several data analysis techniques. These could include descriptive, predictive, and prescriptive analytics using machine learning, text mining, exploratory analysis, and other methods.
  7. Data visualization: After analysis, communicate the results visually, like charts, graphs, dashboards, or other visual tools. Visualization helps you communicate complex insights in an understandable and accessible way.
  8. Interpretation and decision making: Interpret the insights gained from your analysis to draw conclusions and make data-backed decisions. These decisions impact business strategies, processes, and operations.
  9. Feedback and scale: One of the main advantages of big data analytics frameworks is their ability to scale horizontally. This scalability enables you to handle increasing data volumes and maintain performance, so you have a sustainable method for analyzing large datasets.

It’s important to remember that big data analytics isn’t a linear process, but a cycle.

You’ll continually gather new data, analyze it, and refine business strategies based on the results. The whole process is iterative, which means adapting to changes and making adjustments is key.

The importance of big data analytics

Big data analytics has the potential to transform the way you operate, make decisions, and innovate. It’s an ideal solution if you’re dealing with massive datasets and are having difficulty choosing a suitable analytical approach.

By tapping into the finer details of your information, using techniques and specific tools, you can use your data as a strategic asset.

Big data analytics enables you to benefit from:

Types of big data analytics

There are four main types of big data analytics—descriptive, diagnostic, predictive, and prescriptive. Each serves a different purpose and offers varying levels of insight.

Collectively, they enable businesses to comprehensively understand their big data and make decisions to drive improved performance.

Let’s take a closer look at each one.

Descriptive analytics

This type focuses on summarizing historical data to tell youwhat’s happened in the past. It uses aggregation, data mining, and visualization techniques to understand trends, patterns, and key performance indicators (KPIs).

Descriptive analytics helps you understand your current situation and make informed decisions based on historical information.

Diagnostic analytics

Diagnostic analytics goes beyond describing past events and aims to understand why they occurred. It separates data to identify the root causes of specific outcomes or issues.

By analyzing relationships and correlations within the data, diagnostic analytics helps you gain insights into factors influencing your results.

Predictive analytics

This type of analytics uses historical data and statistical algorithms to predict future events. It spots patterns and trends and forecasts what might happen next.

You can use predictive analytics to anticipate customer behavior, product demand, market trends, and more to plan and make strategic decisions proactively.

Prescriptive analytics

Prescriptive analytics builds on predictive analytics by recommending actions to optimize future outcomes. It considers various possible actions and their potential impact on the predicted event or outcome.

Prescriptive analytics help you make data-driven decisions by suggesting the best course of action based on your desired goals and any constraints.

The benefits of big data analytics

Big data analytics has become a clear business game changer by unlocking insights and opportunities.

Below we’ve highlighted some of the tangible benefits of this transformative approach.

Improved risk management

Big data encompasses massive data volumes from diverse sources, including real-time streams. Rapid analysis helps detect anomalies or unusual patterns quickly, preventing risks like fraud or security breaches that can have widespread and immediate consequences.

Example: Banks use big data analytics to spot unusual spending patterns in real-time, helping prevent fraudulent credit card transactions and safeguarding customer accounts.

Cost-efficiency

Big data analytics can process and analyze extensive datasets, including handling large-scale data streams from sources like IoT devices or social media in real time.

This comprehensive analysis enables you to optimize your operations, identify inefficiencies, and reduce costs at a level that might not be achievable with smaller datasets.

Example: Big data analytics optimizes production in manufacturing by analyzing data from sensors on the factory floor, reducing downtime and minimizing maintenance costs.

Better decision making

Applying big data analytics provides deeper insights, as it can analyze diverse and unstructured data types.

You can use it to analyze everything from structured databases to unstructured text and multimedia content. This variety of data sources enables richer insights into customer behavior, market trends, and other critical factors, helping you make more informed and strategic decisions.

Example: An ecommerce platform uses big data analytics to analyze customer browsing behavior and purchase history. This enables personalized recommendations to help improve customer satisfaction and drive sales.

Deeper insights

Big data analytics extracts insights from vast and diverse datasets. This includes structured and unstructured data, making it better at revealing nuanced patterns and hidden relationships.

By delving into massive datasets, big data analytics can uncover insights that have a transformative impact on business strategies and operations.

Example: A healthcare provider uses big data analytics to explore patient data, clinical research, and external sources to find personalized treatment options for complex medical conditions.
