Understanding What Is Big Data Analytics? Importance, Type, Scope And More

Big data has become a driving force behind changes in the way many businesses are run. But what is big data analytics and why is it important? As it spreads to small and medium-sized businesses, big data has the potential to change the way business is done. The term “Big Data” has been used since the early 1990s. The majority of people believe that John R. Mashey, who was employed at Silicon Graphics at the time, popularized the term. 

This blog will tell you everything you need to know about big data. For example, we’ll answer questions like, “What is big data and big data analytics? Why is big data important? What are the possibilities of using big data now?” “How Big Data Analytics work” “Why are big corporations using big data analytics?” and also benefits of big data of big data analytics. Let’s begin.

What is big data and big data analytics?

Big data is an organization’s collection of structured, semi structured, and unstructured data. This sets of complex data can be analyzed for information that can be used in projects involving machine learning, predictive modeling, and other uses of advanced analytics. For large amounts of data to be labeled “big data,” it must possess the five Vs: 

  • Volume
  • Velocity 
  • Variety
  • Veracity 
  • Value

It can be used to find new patterns and trends, which is especially helpful for businesses that want to learn more about how their customers and users think and behave. These insights can help businesses find new ways to be creative and give them a strategic advantage by letting them be the first to offer products and services that aren’t widely available yet.

Big data analytics refers to the process of looking at a large amount of data to find valuable information, such as patterns and insights, correlations, market trends, and customer preferences. With this information, businesses can make better choices.

Examples of big data analytics come in many different forms. Several companies are using big data analytics and analyzing large volume of data to make reports, creating dashboards based on their huge amounts of current and historical data, and developing predictive models. There are numerous ways to analyze big data, including predictive analysis, prescriptive analysis, descriptive analysis, and diagnostic analysis. 

What is big data analytics used for?

Big data analytics is used in many different fields, like health care, education, insurance, retail, artificial intelligence, and manufacturing, to figure out what’s working and what’s not, so that processes, systems, decision making and profits can be improved. For example, big data analytics is essential to the modern health care industry or Banking and Securities industry or retail and wholesale trade for predictive analytics and product development.

Big Data analytics is employed for a variety of purposes. These are some of the most important aspects of using big data analytics.

Cost Reduction

When you start analyzing your customer data, the real costs to serve become clearer. Instead of arbitrarily decreasing expenses, data analytics provides the insight to make strategic adjustments; organizations that can quantify gains through data analysis report an annual cost reduction of 10% on average.

Decision Making

Identifying patterns from large amounts of data is one way in which big data and business analytics can enhance decision making. Identifying problems and providing data to back up solutions is advantageous because it allows you to track whether the remedy solves the problem, improves the situation, or has no effect. Big data analytics is also used in data driven artificial intelligence AI developing for decision making.

Product Research

Big data analytics is one of the most effective methods for gathering and analyzing feedback. It enables you to comprehend how consumers see your services and items. As a result, you can make the required adjustments and further develop your products according to market trends. This makes big data analytics important for both startups and large corporations.

Customer Service

Big data makes it easier to reach customers in a data driven way and find market trends. Processing and analyzing big data can show which channels aren’t connected and where customers drop out of the journey most often. It lets businesses give customers a more personalized experience that helps build customer loyalty. It also helps find the right customers and guess what will happen in the future.

Why is big data important?

Today, Big Data analytics power all online activities—all sectors and fields of social and online media platforms. Using Spotify, you can get music. 96 million users use the site daily which creates countless millions of data. By combining this data, the platform automatically suggests music through an intelligent recommendation engine based on likes, shares, searches and more.

What makes Big Data analytics so valuable is its technology, software tools and framework. Spotify users must have noticed its top recommendations section based on your interests, past experiences, and so forth.

As we’ve already mentioned, big data analytics helps businesses in their systems to enhance operations, provide better customer service, create targeted marketing campaigns, supply chain and carry out other tasks that, in the end, can help them boost sales and be successful. Big data has changed the world in ways that no one could have imagined.

History of Big Data Analytics

Data analytics has its roots back to when computers were first employed when businesses began using computers to collect and manage huge amounts of data. But until the late 90’s and early 2000’s, big data analytics started to emerge as organizations increasingly turned to computer software to help understand rapidly growing amounts of data. Using Big Data analysis today is an essential tool for organizations in any industry.

The evolution of Big Data Analytics

Big Data transforms business intelligence functions by using data as actionable information that adds value. Increasing data analysis and data storage has created new challenges for the capture, storing, and retrieval of information across businesses. In the era the big data analysis has increased in size, with accelerated growth in the volume and variety of data, as well as speed in data acquisition and changing.

Advanced methods and tools for mining and analyzing data with complex structures and data sets, such as XML/Json data, text and image data, multidimensional data, graphs, sequences, and streaming data, are referred to as complex data analytics. This new technology will require significant new requirements to store the data and analyze data, creating a challenge for companies.

Sources of Big Data Analytics

Big data is a huge amount of information from many data sources. That means that it comes from more than one place. There are many different kinds of sources. Here, we’ve talked about the data sources where big data comes from and how they work.

Machine data

Machine data consists of the digital information generated by computers, mobile phones, embedded systems, and other networked devices. As technologies like radio frequency identification (RFID) and telematics improved, this kind of data became more common. It indicates that all information is coming from multiple sources, including smart sensors, SIEM logs, medical devices and wearables, road cameras, IoT devices, satellites, desktops, mobile phones, industrial equipment, etc.

Web data

The public web has a lot of information which is easy to access is free to use. Individuals and businesses have widespread access to information on the Web or Internet. In addition to that, numerous wiki websites make it easy and free for everyone to get information in real time. Start-ups and small and medium-sized businesses (SMEs) benefit from the vast amount of data on the web because they don’t have to build their own big data infrastructure and data repositories to use big data.

Cloud data

Recent years have seen a dramatic rise in the popularity of public cloud computing as the go-to environment for big data projects. Cloud computing allows businesses to access resources and services on demand without investing in, or taking responsibility for, underlying infrastructure. As a result, businesses of all sizes may now benefit from big data technology since they can leverage the cloud’s scalability and reduced costs.

IOT Data

One of the technologies that has the most potential is called IOT, which stands for the Internet of Things. It will make it possible for physical items to connect to the internet, which will result in an improvement to the way in which they function by producing data. It has the capacity to store a vast quantity of data. This is how the Internet of Things has evolved into a source of big data.


Businesses use both old and new databases to get information that is useful to them. This system for collecting and storing data creates a hybrid data model that requires low investment and low IT infrastructure costs. The information in these databases can be analyzed or used to gain valuable insights that help companies make more money. This is also a good source of big data.

Types of big data analytics

data analytics companies

Big data analytics come in a variety of forms depending on the process of analyzing. Different types of analytics serve various purposes, such as determining what actions are the most appropriate to take, imagining conceivable scenarios, detecting a problem from the past, and assessing present events. Big data analytics has four main types: predictive, diagnostic, descriptive, and prescriptive.

Predictive Analytics

Predictive analytics makes use of big data to discover relevant patterns in order to forecast future outcomes and assess the attractiveness of various solutions. Businesses use it to analyze any kind of unknown data from the past, present, or future.

Diagnostic Analytics

The most basic type of data analytics is called descriptive analytics, and it involves describing the most important parts of a data set. Typical strategies for diagnostic analytics include data discovery, drill-down, data mining, and correlations.

Descriptive Analytics

The process of looking at both current and past data to find patterns and connections is Descriptive analytics. It’s the simplest way to look at data because it just talks about trends and relationships without going into more detail.

Prescriptive Analytics

Prescriptive analytics is way to process data to figure out what the best next step is. This type of analysis looks at all the important factors and comes up with suggestions for what to do next. Because of this, prescriptive analytics is a valuable tool for making decisions based on data.

What are the 5 vs of big data analytics

The “5 V’s of Big Data” help us understand the most important parts of big data by pointing out five things that big data always implies. Now, we’ll explain what the 5 Vs of “Big Data” 


Velocity is a measure of how fast data is made and how fast it moves. This is important for businesses that need their data to move quickly so they can use it at the right times to make the best business decisions they can.


There must be many of them. Think about how each user’s actions can be tracked across multiple channels and platforms. The amount of information in even one source could be large, but the density is likely to be low. At first glance, it’s not easy to figure out what all this activity means. Moreover, the vast majority of businesses track considerably more structured and unstructured data.


The value of big data is determined by how useful the information collected is for your business. No matter how much data there is, it’s usually not very useful on its own. To be useful, data needs to be turned into insights or information, which is where data processing comes in.


Variety refers to the different kinds of collected information. This may consist of structured data such as a first name or email address. Alternatively, it could be free-form, like a review of a product. In these situations, processing of data comes before analyzing it.


Veracity is a quality of big data that has to do with continuity, precision, reliability, and validity. Data veracity is about how skewed, noisy, or odd the data is. It can also mean that there are errors, outliers, or missing values in the data.

What is the scope of big data analytics?

Big data analytics is in high demand because it has many applications and advantages. As many industries are starting big data analytics programs it is becoming more wide spread everyday.  The access to defined decisions that it provides makes big data analytics important. Here are some uses and examples of big data that different fields are using.

What is the difference between Data Science and Big Data?

Data science is a catch-all term for all the methods and tools that are used during the life cycle of useful data. On the other hand, it usually refers to very large sets of data that are hard to “use” without using specialized and often new technologies and techniques.

Let’s look at the distinctions between Data Science and Analytics

Data ScienceBig Data
Data science is a field.Big Data is a way to gather, store, and process a lot of information.
It has to do with gathering, processing, analyzing, and using data in different ways. It’s more about ideas.It’s about getting important and useful information out of a lot of data.
It is a discipline similar to computer science, applied statistics, and applied mathematics.It is a way to track and find trends in large sets of complicated data.
The goal is to create data-driven products for a business.The goal is to make data more useful and important by using traditional methods to pull out only the most important information from huge amounts of data.

What is the difference between Data Analytics, Data Analysis, Data Mining, Data Science,Machine Learning, and Big Data?

Data analytics, data analysis, data mining, data science,  machine learning, and big data are all interconnected as they are all under the information technology umbrella. Yet they have some core differences among themselves. Data science is a wide field of science that looks at how to make sense of data. 

Data mining is part of the pipeline for data science. It focuses more on understanding methods and tools to find patterns in data that are new and to make data easier to analyze. Mining data works as a mining operation where big data is the mine. businesses mostly use it to enhance customer experience.

Data science and machine learning are two ideas in the field of technology that help us make and improve products, services, infrastructure systems, and other things by using data management. Making raw data untestable and usable requires some kind of cleaning and transformation.

Data science is a technology that pulls useful information out of large amounts of data. Raw data becomes more sophisticated in the process to become processed data. It is a great tool for machine learning and decision-making. It helps predict future outcomes and take better decisions.

What challenges do businesses face when implementing big data analytics?

Big data is hard because it requires figuring out how to handle a huge amount of data, which means storing and analyzing it in many data warehouses. 

The volume of data, finding patterns correlations from data and using it phases like product development and taking informed decisions are some of the basic challenges of big data analytics.

These are the top five challenges for big data analytics:

Lack of skilled professionals 

Companies need skilled data professionals to run all of these new technologies and big data tools. Data scientists, data analysts, and data engineers will be among these professionals. They will use the tools and figure out what the big data sets mean. QuantHub did a survey that showed there will be a shortage of 250,000 data scientists in 2020. Three-fifths of respondents predicted the most difficulty in attracting data science talent.

Poor data quality costs the U.S. economy around $3.1 trillion per year.


Security Issues

Even though better analysis could help companies make better decisions, it also has some downsides, such as security problems that could get companies into trouble when they are working with sensitive information.

Utilizing Data

Businesses struggle with their big data projects because they don’t understand them well enough. Employees can lack important knowledge about big data analytics, such as how to store data and process it, how important it is, or where it comes from.. People who work with data might know what’s going on, but others might not have a comprehensive vision.

Data Growth

One of the most pressing issues in big data is the proper storage of massive amounts of data. The amount of data that companies store in their data centers and databases is growing quickly. As time goes on, these data sets grow in a way that is hard to handle.

Integration Issues

Data in a business originates from a variety of sources, including social media pages, ERP software, customer logs, financial reports, e-mails, presentations, and reports made by staff. Putting this huge amounts of structured data together to make reports is a tough job. Firms often don’t pay enough attention to this. But data integration is important for analysis, reporting, and business intelligence, so it has to be perfect.
