Data Analytics refers to the set of quantitative and qualitative approaches for deriving valuable insights from data. It involves many processes that include extracting data and categorizing it in order to derive various patterns, relations, connections, and other such valuable insights from it. Today, almost every organization has morphed itself into a data-driven organization, and this means that they are deploying an approach to collect more data that is related to their customers, markets, and business processes. This data is then categorized, stored, and analyzed to make sense out of it and derive valuable insights from it.

Understanding Big Data Analytics
The term ‘Data Analytics’ is not a simple one as it appears to be. It is the most complex term, when it comes to big data applications. The three most important attributes of big data include volume, velocity, and variety.
The need for Big Data Analytics springs from all data that is created at breakneck speeds on the Internet. Our digital lives will make big data even bigger, thanks to the ever-increasing penchant of individuals to see their lives ever-connected to the online world. It is estimated that by the end of the next year the cumulative data that is generated every second will amount to 1.7 MB which will be contributed by every individual on the planet.
This shows the amount of data that is generated and hence the need for Big Data Analytics tools to make sense of all that data. It organizes, transforms, and models data based on the requirements for identifying patterns in the data and drawing necessary conclusions.

The larger the size of the data the bigger the problem. So, big data may be defined as the data the size of which itself poses the problem and which needs newer ways of handling it. So, the analysis of data at high volume, velocity, and variety means that the traditional methods of working with data would not apply here.
‘Without Big Data Analytics, companies are blind and deaf, wandering out onto the web like deer on a freeway.’ – Geoffrey Moore
Why Data Analytics is Important?
Data analysis is an internal arrangement done through presenting numbers and figures to management. With data analytics the organizations will be able to make decisions on customer trends, behavior prediction, increasing the business profits, and drive effective decision-making.
Once the organizations adopt data analytics they can analyze the causes of particular events based on the data, understand the objective and directives for the business, and they can have technical insights of the business using an easy-to-understand language. Here are five reasons why businesses should adopt the data analysis method and technology.
- Better Targeting
Using Data Analytics, organizations can determine what forms of advertising reach their customers effectively and make an impact on them. Data enables the organizations to understand what methods of advertising their product have the biggest impact on the target audience and at what scale the organization could adopt such advertising.
- Bounce Rates
The data that concerns any online business is the bounce rate of their website. Lower bounce rates indicate that customers interested in the business are genuine and they wish to learn more about its offerings. On the other hand, higher bounce rates are a clear signal that something is a miss. It means that either Google or any other search engines are not identifying the business website for its relevance.
A business can have that super successful product that has global applications. Yet, if the business website has a high bounce rate it means that there is an urgent need to review the content. That content and manner in which the business and its offerings are presented need an immediate review.
Gathering data about who is buying products and from which location is also important. It helps the understand whether the business is reaching the right target audience or getting requests or sales from the markets it cannot serve. It can indicate the existence of a market which the business is unaware of and can mark an entry.
Analysis of data regarding the demographic reach of a business also helps understand why there is a larger interest from a specific geographic zone.
- New Innovations
Data analytics also gives the businesses a rough idea of the trends in the future in customer behavior that will also enable the businesses to make futuristic inventions and create new innovative services that will them at the top of the industry. With these inventions, businesses can maintain a sharp edge over their competitors. The good thing about these inventions is that the businesses can patent them and reap from them while at the same time raking profits.
- Cut Costs of Operation
Data analytics will do a lot good if the management wants to have a smooth and effectively run business. With a good data analytics system, the management can determine the sectors of the business that are draining the finances unnecessarily and the areas that need more financing.
How Does Big Data Analytics Make Working so Easy?
There are various tools in Data Analytics that can be successfully deployed in order to parse data and derive valuable insights out of it. The computational and data-handling challenges that are faced at scale mean that the tools need to be specifically able to work with such kinds of data.
The advent of big data changed analytics forever, thanks to the inability of the traditional data handling tools like relational database management systems to work with big data in its varied forms. Data warehouses also could not handle data that is of extremely big size.
The era of big data drastically changed the requirements for extracting meaning from business data. In the world of relational databases, administrators easily generated reports on data contents for business use, but these provided little or no broad business intelligence. It was for that, they employed data warehouses. But, data warehouses too generally could not handle the scale of big data, cost-effectively.
While data warehouses are certainly a relevant form of Data Analytics, the term ‘Data Analytics’ is slowly acquiring a specific subtext related to the challenge of analyzing data of massive volume, variety, and velocity.

Types of Data Analytics
- Prescriptive Analytics: This is the type of analytics that talks about an analysis based on the rules and recommendations in order to prescribe a certain analytical path for the organization.
- Predictive Analytics: Predictive analytics ensures that the path is predicted for the future course of action.
- Diagnostic Analytics: This is about looking into the past and determining why a certain thing happened. This type of analytics usually revolves around working on a dashboard.
- Descriptive Analytics: In descriptive analytics, you work based on the incoming data and for the mining of it you deploy analytics and come up with a description based on the data.
Working with Big Data Analytics
The topic of Data Analytics is a vast one and hence the possibilities are also immense. Prescriptive analytics ensures that it sheds light on various aspects of your business and provide you a sharp focus on what you need to do in terms of Data Analytics. Prescriptive analytics adds a lot of value to any organization, thanks to the specificity and conciseness of this domain. You can deploy prescriptive analytics regardless of the industry vertical based on the same rules and regulations.
Predictive analytics can also ensure that the domain of big data can be deployed for predicting the future based on the present data. A good example of predictive analytics is the deployment of analytical aspects to the sales cycle of an enterprise. It starts with the lead source analysis, analyzing the type of communication, the number of communications and the channels of communication, along with sentiment analysis through heightened use of Machine Learning algorithms and more in order to come up with a perfect predictive analysis methodology for any enterprise.
Diagnostic analytics is used for the specific purpose of discovering or determining why a certain course of action happened. For example, one can work with diagnostic analytics to review a certain social media campaign for coming up with the number of mentions for a post, the number of followers, page views, reviews, fans, and such other metrics to diagnose why a certain thing happened.
Descriptive analytics is the least popular which is basically used for coming up with a methodology for uncovering patterns that can add value to an organization. As an example, you can think about the credit risk assessment. It involves predicting how likely a certain customer is to default based on his credit history. It takes into consideration various aspects like the financial performance of the customer, inputs from past financial institutions that the person might have approached and other platforms like social media, and online presence based on the web-based solutions.
Since no organization today can stay without being inundated with data, it is imperative that Data Analytics is an indispensable part of the life cycle of data in any organization . Based on various types of Data Analytics, today’s forward-looking enterprises can actually go ahead and design a very robust path to success with the data they have.
‘If you torture the data long enough, it will confess.’ – Ronald Coase, Economist.

Data Analyst vs Business Analyst
While both the Data Analysts and Business Analysts work with the data, the main difference lies in what do they do with it. Business Analysts use data to help organizations make more effective business decisions but in the contrast, Data Analysts are more interested in gathering and analyzing data for the business to evaluate and use to make decisions on their own.
In the simplest terms, data is a means to the end for business analysts, while data is the end for data analysts.
Companies Using Data Analytics
Today, regardless of the industry type, there is rapid deployment of various analytical tools and technologies. It could be the tools for parsing data or the easy-to-understand visualization tools which are used for making sense of the data.
