What is Big Data?

Writer : Angle Marque EG

Big data defined The term "big data" refers to data that is more diverse, larger in volume, and faster in delivery. The three Vs are another name for this.

"Big data" is a term used to describe data sets that are larger and more complex. Traditional data processing software simply cannot handle the sheer volume of these data sets. However, these enormous amounts of data can be used to solve business problems that you couldn't have previously.

The three Vs of big data


The amount of data is important. " You'll have to deal with a lot of low-density, unstructured data when dealing with big data. We're talking about data that has no inherent value, such as data from a sensor-enabled device or a Twitter feed. Several petabytes of data may be involved for some organizations. It could be hundreds of petabytes for others.


The rapidity with which data is received and (possibly) acted upon is referred to as "velocity." As opposed to being written to disk, data typically flows into memory at the fastest possible rate. Real-time or near-real-time operation is a requirement for some internet-enabled smart products.


Variety is a term used to describe the wide range of data that can be accessed. Relational databases favored structured data types because of their ease of use. The rise of big data has resulted in a variety of new, unstructured data types. In order to derive meaning and support metadata, it is necessary to perform additional preprocessing on unstructured and semistructured data types such as text, audio, and video.

The value—and truth—of big data

Value and veracity are new Vs that have emerged in recent years. The value of data cannot be overstated. That value will not be discovered until it is too late. It's also critical to ask: How accurate and dependable is your data?

Big data is now a form of currency. Think of some of the world's most prominent technology companies. They are constantly analyzing their data in order to produce more efficiency and develop new products, which provides a large portion of their value.

The cost of data storage and computation has decreased dramatically in recent years, making it easier and more affordable to store more data than ever before. You can now make more accurate and precise business decisions thanks to an increase in the volume and accessibility of big data.

It's not enough to analyze large amounts of data to derive any value from it (which is a whole other benefit). Analysts, business users, and executives must be able to ask the right questions in order to identify patterns and predict future behavior.

Who knows where this all began.


The history of big data

Although the term "big data" is relatively new, large data sets can be traced back to the 1960s and '70s, when the first data centers and relational databases were being developed.

Facebook, YouTube, and other online services began to generate a lot of data around 2005. That same year, Hadoop (an open-source framework designed to store and analyze large data sets) was developed. At this time, NoSQL also became popular.

This growth in the field of big data could not have occurred without the development of open-source frameworks such as Hadoop (and more recently, Spark). Since then, the amount of big data has increased dramatically. There is still a lot of data being generated by users, but it's not just humans doing it.

More and more objects and devices are being linked to the internet via the Internet of Things (IoT), allowing for the collection of data on customer usage patterns and product performance. More data has been generated due to the rise of machine learning.

Although big data has come a long way, its usefulness is still in its infancy. Big data is now even more accessible thanks to the rise of the cloud. As a result, the cloud provides the ability to quickly spin up ad-hoc clusters to test a small portion of data. It is also becoming increasingly important to use graph databases, which are capable of displaying huge volumes of information quickly and comprehensively.

Big data benefits:

  • Big data allows you to get more accurate answers because you have access to more data points.
  • Complete answers imply a higher level of trust in the data, which necessitates a new strategy for dealing with issues.

Big data use cases

There are a number of business activities that can benefit from using big data, including customer service and analytics. Here are a few examples.

Product development

In order to anticipate customer demand, companies like Netflix and Procter & Gamble rely on big data. In order to build predictive models for new products and services, they classify and model the relationship between key attributes of past and current products or services and the commercial success of the offerings. As a result, P&G uses data and analytics derived from focus groups and social media as well as test markets and early store rollouts to plan, produce, and launch new products.

Predictive maintenance

Unstructured data, such as the millions of log entries, sensors, error messages, and engine temperature, may contain information that can help predict mechanical failures that are not readily apparent in structured data, such as the year, make, and model of the equipment. Organizations can save money and increase equipment and part uptime by analyzing these signs of potential problems before they occur.

Customer experience

There's a battle for customers' attention. Now more than ever, it is possible to get a clearer picture of the customer's experience. Improve the customer experience and maximize the value delivered by analyzing data from social media, web visits, call logs, and other sources using big data Reduce customer churn by delivering personalized offers and taking proactive measures to address problems.

Fraud and compliance

It's a rat-race for customers. A better understanding of the customer experience is now possible than at any time in history. There are many ways in which you can use big data to improve the customer experience and maximize the value that is delivered. Reduce customer churn and deal with problems before they arise by delivering personalized offers and taking proactive measures to resolve them.

Machine learning

There is a lot of interest in machine learning at the moment. Big data, in particular, is a factor in this. Instead of programming machines, we can now teach them. Machine learning models can be trained using large datasets thanks to the availability of big data.

Operational efficiency

Operational efficiency is an area where big data is having the most impact, even if it isn't always in the headlines. As a result of using big data analytics, you can reduce downtime by analyzing and assessing production, customer feedback, and returns, and other factors. Big data can also be used to enhance decision-making in line with current market demands.

Drive innovation

Using big data, you can discover new ways to use your insights by analyzing the interdependencies between people, institutions, entities, and processes. Improve financial and planning decisions using data insights. Determine what customers want in terms of new products and services by looking at trends and market data. Put in place dynamic pricing. There is no limit to what can be done.


Big data challenges

Big data has a lot of potential, but it also has some drawbacks.

First and foremost, big data is, well, big. Although new data storage technologies have been developed, data volumes are doubling every two years approximately. Organizations are still unable to keep up with the rapid growth of data and devise efficient methods for archiving it.

However, merely archiving the information is insufficient. In order to be valuable, data must be used, and curation plays a key role in this. Much effort goes into ensuring that data is relevant to the customer and organized in such a way that it can be analyzed meaningfully. More than half of their time is spent preparing and organizing data before it can be put to use.

Finally, big data technology is evolving quickly. Apache Hadoop was a popular tool for dealing with large amounts of data a few years ago. Afterwards, in 2014, Apache Spark was made publicly available for use. Today, it appears that the best strategy is to combine the two frameworks. As big data technology continues to advance, it's difficult to keep up.

How big data works

Insights gleaned from large data sets can pave the way for entirely new business models and revenue streams. In order to get started, there are three main steps:

1.  Integrate

The term "big data" refers to the aggregation of information gleaned from numerous sources and applications. Extract, transform, and load (ETL) isn't up to the task of integrating large amounts of data. New approaches and technologies are needed to analyze large data sets at terabyte or even petabyte scale.

In order for your business analysts to get started, you need to bring in the data, process it, and make sure it is available in a format they can use.

2.  Manage

Large amounts of data necessitate a variety of storage options. Storage can be on-premises, in the cloud, or a combination of both. It's up to you how you want to store your data and how you want to bring your desired processing requirements and necessary process engines to those data sets. It's common for people to choose a storage solution depending on where their current data is located. You can use the cloud to meet your current computing needs, and you can quickly spin up additional resources as needed.

3.  Analyze

Analyzing and acting on your data will pay off your big data investment. Visually analyzing your various data sets can help you see things more clearly. Make new discoveries by examining the data further. Educate others about what you've learned. Using machine learning and artificial intelligence, create data models for your organization. Put your information to use.

Big data best practices

We've compiled a list of best practices to keep in mind as you embark on your big data journey. The following are our recommendations for laying a solid foundation for big data.

Connect big data to your company's strategic objectives.

You can make new discoveries with larger datasets. A strong business-driven context must be established for any new investments in skills, organization, or infrastructure in order to ensure that future project investments and funding are secured. Check to see if your top business and IT priorities are being supported and facilitated by the use of big data. There are many examples of this, such as understanding the importance of filtering web logs to understand ecommerce behavior, deriving sentiment from customer support interactions via social media and analyzing statistical correlation methods.

By implementing standards and governance, you can help alleviate the shortage of skilled workers.

In order to reap the rewards of your big data investment, you'll need to fill a skills gap. Adding big data technologies, considerations, and decisions to your IT governance program can help reduce this risk. You'll be able to keep costs down and maximize resources if you standardize your approach. Organizations implementing big data solutions and strategies should regularly assess their skill requirements and identify any potential gaps in their staff's abilities. Training and cross-training current employees, hiring new employees, and enlisting the help of consulting firms are all ways to address these issues.

With a center of excellence, maximize knowledge transfer

Share information, keep an eye on things, and keep the lines of communication open with a center of excellence approach. Soft and hard costs can be shared across the enterprise whether it is a new or expanding investment in big data technology. Using this method, you can more systematically and systematically improve your big data capabilities and the maturity of your information architecture.

Aligning unstructured and structured data yields the greatest return on investment.

Analyzing large amounts of data on its own has its advantages. However, by integrating low-density big data with the structured data you already have, you can gain even more business insights.

You want to add more relevant data points to your core master and analytical summaries so that you can draw better conclusions, whether you're capturing customer, product, equipment or environmental big data. There is a difference, for example, between identifying the sentiment of all customers and identifying the sentiment of only your best customers. For this reason and others, big data is seen as an extension of existing business intelligence, data warehousing platforms, and information architectures.

It's important to remember that the methods and models used to analyze large amounts of data can be based on either human or machine labor. Big data analytics include statistical, spatial, semantic, interactive, and visualization capabilities. It is possible to make meaningful connections and correlations by using analytical models.


You must plan the performance of your discovery lab.

Making sense of data isn't always an easy task. Most of the time, we have no idea where to begin our search. That's to be expected, unfortunately. It is imperative that IT and management work together to address this "lack of direction."

Analysts and data scientists must also work closely with the business to identify and fill knowledge gaps and requirements. There must be high-performance workstations to accommodate interactive data exploration and experimentation with statistical algorithms Ensure that sandbox environments have the resources they require, and that they are properly governed.


Assemble a cloud-based operating system

Many resources are needed by both the big data processes and users in order to carry out iterative experiments and run production jobs. Transactions, master data, reference data, and summarized data are all part of a big data solution. Sandboxes should be created as and when necessary. Controlling all aspects of the data flow, from collection to analysis, is impossible without effective resource management. A well-thought-out provisioning and security strategy for both private and public clouds is critical to keeping pace with these ever-evolving demands.
