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:
- 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.
- 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.
- 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.
- Data integration: Data usually comes from various sources in different formats. Data integration combines the data into a unified format.
- 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.
- 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.
- 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.
- 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.
- 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.

Types of big data analytics
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.
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 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.
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 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.
