Big Data Analytics: How It Works and Its Benefits [2024]

Big Data Analytics

Your clients create a lot of data every day. Those technologies collect and analyze the data for your company every time customers read your email, use your mobile app, tag you on social media, come into your store, make an online purchase, speak with a customer service person, or ask a virtual assistant about you. That’s simply your customers. Employees, supply chains, marketing initiatives, finance departments, and others all create a lot of data every day. Big data refers to a massive amount of data and datasets that may be found in a variety of formats and from a variety of sources. Many businesses have realised the benefits of gathering as much data as possible.

But collecting and storing huge data isn’t enough; you also need to put it to use. Organizations can utilize big data analytics to turn terabytes of data into useful insights, thanks to constantly evolving technologies.

What is big data analytics?

The process of identifying trends, patterns, and correlations in large amounts of raw data in order to make data-informed decisions is known as big data analytics. These procedures use well-known statistical analysis approaches, such as clustering and regression, and apply them to larger datasets using modern tools. Since the early 2000s, when software and hardware capabilities enabled businesses to manage massive volumes of unstructured data, big data has been a buzzword. Since then, new technologies have added even more to the massive volumes of data available to businesses, from Amazon to cell phones. Early innovation initiatives like Hadoop, Spark, and NoSQL databases were established to store and handle big data as a result of the explosion of data.

Data experts are still working out how to combine the massive volumes of complicated data generated by sensors, networks, transactions, smart devices, online traffic, and other sources. Even now, new technologies like machine learning are being utilised with big data analytics methodologies to identify and scale more complex insights.

How big data analytics works

How big data analytics works

Big data analytics is the process of gathering, processing, cleaning, and analysing enormous datasets in order to assist businesses to operationalize their data.

1. Collect Data

Every organization’s data collection looks different. Organizations may now collect both structured and unstructured data from a range of sources, ranging from cloud storage to mobile applications to in-store IoT sensors and beyond, thanks to today’s technologies. Some data will be housed in data warehouses, where it will be accessible to business intelligence tools and solutions. A data lake can be used to store unstructured or raw data that is too diverse or complex for a warehouse to handle.

2. Process Data

Once data has been collected and saved, it must be correctly organised in order to yield reliable answers from analytical queries, particularly when the data is huge and unstructured.

Data specialists are brought in after the data has been collected and stored to split and configure the data for analytical queries. In general, there are two methods for processing data:

Batch processing: Batch processing processes large data blocks over time. When a company has enough time between data collection and analysis, the batch method is advantageous.

Steam processing: Steam processing processes a small data batch at once, shortening the delay period between collecting and analyzing data. The Steam method is more complicated and costly than a batch process, and it is typically utilised when management has to make speedy choices.

3. Clean Data

To increase data quality and provide stronger results, all data must be presented appropriately, and any redundant or unnecessary data must be removed or accounted for. Dirty data may obscure and deceive, leading to incorrect conclusions.

4. Analyze Data

It takes time to turn huge data into usable information, and even then, you might need to have a data analytics glossary. Once you have the information, advanced analytics procedures can transform this data into big insights. Some examples of large data analysis approaches are as follows:

Data mining sifts through massive databases to locate patterns and correlations by detecting anomalies and forming data clusters.

Predictive analytics produces future predictions based on historical data, detecting prospective threats and opportunities.

Deep learning, which simulates human learning processes, combines artificial intelligence and machine learning to stack algorithms and identify patterns in the most difficult and abstract data.

Big data analytics tools and technology

Big data analytics tools and technology

Big data analytics is too broad to be summed up in a single tool or technique. Instead, a combination of technologies is used to gather, process, cleanse, and analyse large amounts of data. The following is a list of some of the most important actors in big data ecosystems.

Hadoop: Hadoop is an open-source system for storing and processing large datasets on commodity hardware clusters. This framework is open-source and capable of handling massive volumes of organised and unstructured data, making it an essential component of any big data project.

NoSQL: NoSQL databases are non-relational data management systems that don’t require a set schema, making them an excellent choice for large amounts of unstructured data. The term “not only SQL” refers to the fact that these databases can handle a wide range of data models.

MapReduce: MapReduce is a key component of the Hadoop architecture that serves two purposes. The first is data filtering and distribution among cluster nodes, which is called mapping. The second method is reduction, which organises and condenses the results from each node in order to respond to a query.

YARN: YARN stands for “Yet Another Resource Negotiator,” and it is a second-generation Hadoop component. Job scheduling and resource management in the cluster are aided by cluster management technologies.

Spark: Spark is an open-source cluster computing framework that provides an interface for programming whole clusters by utilising implicit data parallelism and fault tolerance. For quick computing, Spark can perform batch and stream processing.

Tableau: Tableau is a full-featured data analytics platform that lets you prepare, analyse, collaborate, and share big data insights. Tableau is a leader in self-service visual analysis, allowing users to ask new questions of managed large data and quickly share their findings throughout the company.

The big benefits of big data analytics

Any corporate organisation may benefit from the capacity to evaluate data more rapidly since it allows them to swiftly answer crucial questions.

Big data analytics is significant because it helps businesses to analyse large amounts of data from diverse sources to find possibilities and threats, allowing them to operate more swiftly and efficiently. The following are some of the advantages of big data analytics:

Cost-efficiency – Assisting businesses in developing more effective and efficient methods to conduct business.

Product Development – Assisting businesses in developing more effective and efficient methods to conduct business deeper goods are developed as a result of a better knowledge of customers’ wants and preferences.

Market knowledge – Observing market trends and client purchasing patterns.

Benefits & Advantages of Big Data Analytics

1. Risk Management

Use Case: Big Data analytics is used by Banco de Oro, a Philippine financial business, to detect fraudulent activity and discrepancies. It is used by the organisation to narrow down a list of suspects or underlying causes of issues.

2. Product Development and Innovations

Use Case: Rolls-Royce, one of the world’s major makers of jet engines for airlines and military forces, use Big Data analytics to determine how efficient engine designs are and whether any upgrades are required.

3. Organizational decision-making that is faster and better

Use Case: Starbucks makes strategic decisions based on Big Data analytics. For example, the company will utilize it to decide whether a given location is suitable for a new store. They’ll consider factors such as population, demographics, geographical accessibility, and more.

4. Improve Customer Experience

Use Case: Big Data analysis is used by Delta Air Lines to improve customer experiences. They keep an eye on Twitter to find out about their clients’ journeys, delays, and other issues. The airline monitors bad tweets and takes appropriate action to rectify the problem. It helps the airline create positive customer relations by publicly addressing these concerns and proposing remedies.

The big challenges of big data

Big data has a lot of advantages, but it also has a lot of drawbacks, such as new privacy and security concerns, accessibility for business users, and selecting the best solutions for your needs. To make the most of incoming data, businesses must handle the following issues:

Making big data accessible – As the volume of data expands, collecting and analysing it gets increasingly complex. Data owners of all skill levels must be able to use data easily and conveniently.

Maintaining quality data – Organizations are spending more time than ever before cleaning for duplication, mistakes, absences, conflicts, and inconsistencies because they have so much data to manage.

Keeping data secure – As the volume of data expands, so do worries about privacy and security. Before making use of big data, businesses must strive for compliance and implement stringent data protocols.

Finding the right tools and platforms – New methods for processing and analysing large amounts of data are constantly being developed. Organizations must discover the correct technology to fit into their existing ecosystems and meet their specific requirements. Often, the best solution is also the most adaptable, allowing for future infrastructure upgrades.


Because information is power in the digital era, it is reasonable to claim that big data analytics today controls the commercial markets. Businesses are using big data analytics to discover the hidden truths under the huge statistics they acquire from various sources. Without big data analytics, thriving in competitive business marketplaces is a pipe dream.
