Everyone is talking about big data analytics these days, making it the hottest buzzword in town. But why is that?

The amount of data generated every day by individuals and organizations throughout the world is enormous, estimated at 2.5 quintillion bytes. Because the world revolves around data, businesses constantly look for new and better ways to leverage it to achieve greater heights. As a result, big data analytics grew in value seemingly overnight.

Big data analytics is the process of analyzing massive amounts of data to find hidden patterns, correlations, and other insights. With today’s technology, it can analyze data and get answers practically instantly — a huge leap forward from more traditional business intelligence solutions that are slower and less efficient.

Here is a comprehensive overview of the science to make data-informed decisions known as big data analytics. These procedures take well-known statistical analysis approaches, such as clustering and regression, and apply them to big datasets using newer tools.

Since the early 2000s, when software and hardware capabilities enabled organizations to handle big amounts of unstructured data, big data has been a buzz. Since then, new technologies have added even more to the big volumes of data corporations can now access.

Data engineers are currently working to find new ways to integrate the large amounts of complex data generated by sensors, networks, transactions, smart devices, web traffic, and other sources. Big data analytics methodologies combine with emerging technologies such as machine learning to uncover and scale more sophisticated insights.

Types of big data analytics

There are four types of big data analytics:

Descriptive analytics

Descriptive analytics is a type of big data analytics in which historical data is gathered, organized, and presented understandably. Descriptive analytics is solely concerned with what has already occurred in a company, and unlike other types of analysis, it does not make assumptions or predictions based on its results.

Moreover, descriptive analytics is a basic starting point for interpreting or preparing big data for later analysis.

Diagnostic analytics

Diagnostic analytics can figure out what created a certain issue in the first place. Drill-down, data mining, and data recovery are just a few of the basics of diagnostic analytics.

Diagnostic analytics is a type of big data analytics used by businesses because they provide a detailed understanding of a problem based on big data.

Predictive analytics

While descriptive analytics is concerned with big historical data, predictive analytics is a type of big data analytics concerned with foreseeing and understanding what may occur in the future.

Analyzing historical data and customer insights to forecast what will happen in the future can help a company set realistic goals, plan effectively, manage performance expectations, and minimize risks.

Prescriptive analytics

Whereas descriptive analytics explores what has happened and predictive analytics forecasts what could happen, prescriptive analytics is a type of big data analytics that explains what should happen.

This methodology is the fourth, last, and most advanced step of the big data analytics process. It motivates firms to take action by assisting executives, managers, and operational staff in making the best decisions possible based on the data at hand.

Big data analytics tools

Big data analytics is too broad to be summed up in a single big data analysis tool or technology. Instead, a combination of tools gets used to collect, process, cleanse, and analyze large amounts of data. The following is a list of some of the most important big data analysis tools:


Hadoop is an open-source system for storing and processing big data on commodity hardware clusters. This free big data and data analytics tool can manage massive amounts of organized and unstructured data, making it an essential component of any big data operation.

NoSQL databases

NoSQL databases are non-relational data management systems that do not require a set schema, making them an excellent choice for large amounts of unstructured data. NoSQL stands for “not only SQL,” These databases can handle a wide range of data models, making them one of the most powerful big data and data analytics tools available.


MapReduce is a big data and data analytics tool, a key component of the Hadoop framework that serves two purposes. The first is mapping, which filters data and distributes it among cluster nodes. The second method is reducing, which organizes and condenses the results from each node to respond to a query.


YARN stands for “Yet Another Resource Negotiator.” YARN is a component of Hadoop’s second generation. This cluster management technology aids job scheduling systems and resource management.


Tableau is a full-featured big data and data analytics tool that lets users prepare, analyze, collaborate, and share big data insights. Tableau is a leader in self-service visual analysis, allowing users to ask new questions about managed big data and quickly share their findings across the company.

Benefits of using big data analytics

The benefits that big data analytics hold are expansive.

Big data analytics allows businesses to evaluate their data in its entirety swiftly, and some even provide real-time analysis. Enterprises that use big data analytics may drive innovation and make the best business decisions using high-performance data mining, predictive analytics, text mining, forecasting, and optimization.

Furthermore, big data analytics allows businesses to focus their big data on the most important information and analyze it to make vital business decisions. This proactive approach to business is transformational because it allows and benefits analysts and decision-makers to go forward with the most up-to-date information and insights, frequently in real-time.

These further benefit companies since they may improve customer retention, develop better goods, and gain a competitive advantage by responding quickly to market changes, indicators of crucial customer shifts, and other business KPIs.

Ultimately, companies that use all of the big data analytics tools, applications, platforms, or solutions available to them get positioned to optimize machine learning and meet their big data demands in novel ways.

Applications of big data analytics

As previously stated, big data analytics is significant because it allows firms to leverage big amounts of data in various forms from many sources to detect possibilities and threats, allowing them to move swiftly and improve their bottom lines.

With that, big data is finding usage in almost all industries today, especially in the healthcare and financial industries.


Big data analytics applications can utilize a patient’s medical history to estimate how likely they will experience health problems. To make good use of data generated during censuses and surveys, health ministries in many nations include and apply big data analytics systems and processes.

More specifically, here are some examples of big data analytics applications in the healthcare sector:

Patient predictions for better staffing systems

One of the most common problems that each shift manager confronts is deciding how many personnel to deploy at any particular time. Big data analytics assists in the solution of this problem by creating a web-based user interface that estimates patient loads and aids in resource allocation planning through the use of online data visualization to enhance overall patient care.

Electronic health records (EHRs)

One of the most important examples of big data analytics applications is creating electronic health records (EHRs).

Every patient has a digital record. These records are shared through secure information systems and are accessible to both public and private sector providers.

Furthermore, each record gets a single modifiable file containing all relevant data, allowing doctors to make changes over time with no paperwork and no risk of data replication.

Real-time alerting

Other examples of advanced data analytics in healthcare have one thing in common: real-time alerts. Big data analytics assists health practitioners in analyzing medical data on the fly and providing recommendations while they make prescriptive decisions based on the available data.
