Why Learn Big Data Analytics?

Big Data analytics is the process of gathering, managing, and analyzing large sets of data (Big Data) to uncover patterns and other useful information.  These patterns are a minefield of information and analysing them provide several insights that can be used by organizations to make business decisions. This analysis is essential for large organizations like Facebook who manage over a billion users every day, and use the data collected to help provide a better user experience.  

Similarly, LinkedIn provides its users with millions of personalized suggestions on a regular basis. LinkedIn does it with the help of components like HDFS features and MapReduce in Big Data Analytics. Big Data has thus become an indispensable part of technology and our lives; and big data analyses provides solutions that are quick and require reduced effort to generate. It is no wonder then that big data has spread like wild fire and so have the solutions for its analyses.

According to a recent McKinsey report the demand for ‘Big Data’ professionals could outpace the supply by 50 to 60 percent in the coming years, and U.S.-based companies will be looking to hire over 1.5 million managers and big data analysts with expertise on how big data can be applied. Big Data investments have also sky rocketed, with several top profile companies spending their resources on Big Data related research and hiring big data analysts to change their technology landscape.

An IBM listing states that the demand for data science and analytics is expected to grow from 3,64,000 to nearly 27,20,000 by 2020. According to a recent study done by Forrester, companies only analyze about 12% of the data at their disposal. 88% of the data is ignored, mainly due to the lack of analytics and repressive data silos. Imagine the market share of big data if all companies start analysing 100% of the data available to them. Hence the conclusion is that there is no time like now to start investing in a career in big data. It is paramount that developers upskill themselves with analytical skills and get ready to take a share of the big data career pie.


Big data analytics certification is growing in demand and is most relevant in data science today than in other fields. The field of data analytics is new and there are not enough professionals with the right skills. Hence, the credibility of big data analytics certification promises many growth opportunities for organizations as well as individuals in the booming field of data science.

Many big companies like Google, Apple, Adobe, and so on are investing in Big Data. Let’s take a look at the benefits of Big Data that organizations and individuals are experiencing:

  • An individual with Big Data analytics skills can make decisions more effectively
  • Based on the IBM survey, the Big Data analytics job market is expected to grow by 15% in the year 2020
  • According to Glassdoor, Big Data Engineers are earning an average of $116,591 per annum
  • An individual with Big Data skills can earn a better salary, good career growth, and more chances of getting hired by top companies
  • Big Data allows organizations to understand consumer needs and make informed decisions
  • Big data tools can identify efficient ways of doing business through sentiment analysis
  • Businesses can get ahead of the competition by better understanding market conditions
  • With Big Data Analytics, organizations understand ongoing trends and develop products accordingly.

Certification FAQs

Big Data Analytics Course

Big Data refers to large amounts of structured and unstructured data that can be analysed using traditional databases and multiple software techniques to reveal patterns that can be used to meet business objectives. Analyses of such large amounts of unstructured data helps in understanding and predicting human behaviour and solving complex business problems. Big Data is huge and consists of complex data sets that traditional data processing software cannot manage.

Big data contains in it patterns and information which when mined can given an insight into customer behavior and preferences. This leads to new innovations, satisfied customers, smoother operations and higher profits. Let’s see the attributes that are making Big Data so popular today:

  • Reduced Cost:

With the help of Big Data technologies like Hadoop and cloud-based analysis, organizations find out more efficient ways of doing business and bring cost advantages when it comes to storing huge amounts of data.

  • Quick & Improved Decision Making:

With the help of Hadoop and in-memory analytics, organizations can quickly analyze the data and will be able to make decisions based on their learnings.

  •  Latest products and services:

Big Data helps businesses gauge customer requirements and preferences, based on which they can develop new products or improve existing products to meet customer needs.

Tons of data are generated every second from our activities on social networks, the internet, or even from traditional business systems. This data generated from various sources is very complex and unstructured, and requires analysis to make it useful.

Data Analytics technologies provide organizations the means to analyse the data and draw conclusions, which further helps them improve their business models and create a better experience for their customers.  Big Data Analytics is an advanced form of analytics which involves several elements like statistical analysis, what-if, and predictive models. There are a lot of tools and applications that enable analysts and data scientists to analyse different forms of data that cannot be handled by the usual BI applications.

The difference between Big Data and Big Data analytics is that the former is a dataset that is not refined and is unstructured and is collected from various sources. Big Data Analytics, on the other hand, is clean and clear data that is easier to access and more concise.

To elaborate, Data Analytics is more accurate and focused than Big Data because instead of gathering dumps of unstructured data, analysts have a specified goal and sort through data to look for solutions to specific problems. Whereas Big Data is just a collection of a huge volume of data that requires a lot of filtering to derive any sort of usage or insight from it.  Additionally, another notable difference between them is that Big Data employs more complex tech tools to handle data, but Analytics uses statistics and predictive modelling with simpler tools.

Big Data Analytics tools include:

  1. Tableau Public
  2. OpenRefine
  3. KNIME
  4. RapidMiner
  5. Google Fusion Tables
  6. NodeXL
  7. Wolfram Alpha
  8. Google Search Operators
  9. Solver
  10. Dataiku DSS

There are 7 widely used Big data techniques:

  1. Association rule learning
  2. Classification tree analysis
  3. Genetic algorithms
  4. Machine learning
  5. Regression analysis
  6. Sentiment analysis
  7. Social network analysis

There are several techniques that are used for Big Data analysis. Some of them are:

  1. A/B Testing: It is a technique in which a control group is compared with a variety of test groups in order to determine what treatments (i.e., changes) will improve a given objective variable, such as say, marketing response rate. This technique is also known as split testing or bucket testing.
  2. Association rule learning: This is a set of techniques for discovering interesting relationships, i.e., “association rules,” among variables in large databases. These techniques consist of a variety of algorithms to generate and test possible rules. One application is market basket analysis, in which a retailer can determine which products are frequently bought together and use this information for marketing purposes (a commonly cited example is the discovery that many supermarket shoppers who buy diapers also tend to buy beer).
  3. Classification: A set of techniques to identify the categories to which new data points belong, based on a training set containing data points that have already been categorized. One application is the prediction of segment-specific customer behaviour (e.g., buying decisions, churn rate, consumption rate) where there is a clear hypothesis or objective outcome.
  4. Cluster analysis: A statistical method for classifying objects that split a diverse group into smaller groups of similar objects, whose characteristics of similarity are not known in advance. An example of cluster analysis is segmenting consumers into self-similar groups for targeted marketing.
  5. Crowdsourcing: A technique for collecting data submitted by a large group of people or community (i.e., the “crowd”) through an open call, usually through networked media such as the Web.
  6. Data fusion and data integration: A set of techniques that integrate and analyze data from multiple sources in order to develop insights in ways that are more efficient and potentially more accurate than if they were developed by analyzing a single source of data.
  7. Data mining: A set of techniques to extract patterns from large datasets by combining methods from statistics and machine learning with database management. These techniques include association rule learning, cluster analysis, classification, and regression.

Big Data comprises of specific attributes in the form of 4 V’s. They are:

  1. Volume
  2. Variety
  3. Velocity
  4. Veracity

Big data is present in 3 forms:

  • Structured

Structured data is the data that can be processed, stored, and retrieved in a preset form. 

  • Unstructured

Unstructured data is the data that lacks any specific structure.

  • Semi-structured

Semi-structured data is the data that is the combination of both the formats i.e. structured and semi-structured.

Data is basically the quantities, characters, or symbols on which operations are performed by a computer, which may be stored, transmitted or recorded. Big Data is also data but with a large size. Big Data is a term used to describe a collection of data that is large in size and may grow exponentially with time. Big data sets are so large and complex that none of the traditional data management tools are able to store or process it efficiently. Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process the data within a tolerable elapsed time.

Data Warehousing is extracting data from one or more homogeneous or heterogeneous data sources, transforming the data and loading that into a data repository to do data analysis which further helps in taking better decisions to improve one’s performance and in reporting.

Big data refers to volume, variety, and velocity of the data. How big the data is, the speed at which it is coming and the variety of data, determine the so-called “Big Data”.  The 3 V’s of big data was articulated by industry analyst Doug Laney in the early 2000s.

Organizations want a big data solution because in many corporations there are many operations associated with a large amount of data. And in those corporations, if data contains much valuable information then it can lead to better decisions, which subsequently leads to more revenue, more profit, and more clients.

Organizations need a data warehouse in order to access reliable data and make informed decisions. Big data solution is a technology whereas data warehousing is an architecture.

Top big data technologies are divided into 4 fields which are classified as follows:

  • Data Storage
  • Data Mining
  • Data Analysis
  • Data Visualization

Data storage: For big data projects, cloud-based storage tools are vital to maximizing the amount of information you can store. Cloud storage options let you store data in a secure and accessible fashion, for ease of use.

Data mining: Once you have your data stored, you will need some tools to find the information you want to analyze or visualize. This tool helps you to extract the data you need without the hassle of manually trawling through it all (a task that's impossible for humans to do anyway if you hold thousands or more records).

Data analysis: Got the data you need? Now it's time to find the most powerful tools to help you analyze it in order to glean key insights into your business, your customers or the wider world.

Data Visualization: Not everyone is adept at taking key insights from a list of data points or understanding what they mean. The best way to present your data is by turning it into visuals that everyone can comprehend easily.

Big data analytics is the complex process of examining large and varied data sets, or big data, to uncover information -- such as hidden patterns, unknown correlations, market trends and customer preferences -- that can help organizations make informed business decisions. On a broad scale, data analytics technologies and techniques provide a means to analyze data sets and draw conclusions about them, which helps organizations make informed business decisions. Business intelligence (BI) queries answer basic questions about business operations and performance.

Big data analytics is a form of advanced analytics, which involves complex applications with elements such as predictive models, statistical algorithms and what-if analysis powered by high-performance analytics systems.

Driven by specialized analytics systems and software, as well as high-powered computing systems, big data analytics offers various business benefits, including:
