Introduction to Big Data Analytics
Big Data is a term which refers to an enormous amount of data ranging from Terabytes to even Exabyte and more. The process of analyzing data sets about the information they include to draw inferences, frequently with the support of specialized technologies and tools are referred to as Big Data Analytics. It is widely used in business industries and other organizations to make better business conclusions.
Definition
The most important thing here is what the Organizations do with these data available? With fast-growing technologies, it is a nightmare for companies to derive meaningful insights from data generated on a day-to-day basis. With the introduction of the Big Data analytics concept, an organization collects data from various externals sources such as mobile devices, social media feeds, measuring instruments, forecast reports, IoT devices, relational database servers, and several other sources. These data can be formatted, manipulated and analyzed in a better way to provide solutions to business problems, gain knowledge about the customer trend, sentimental analysis on people, increase revenue and an increase in operational performance.
Understanding the V’s of Big Data
Let us look at the popular V’s of Big Data.
1. VOLUME
Handling and processing a large amount of data is a common problem. Big data makes use of other technologies such as Hadoop, Apache Spark, and HDFS to perform the tasks at ease.
2. VELOCITY
Organizations collect data at high speed to process instant outcomes. Big Data can cope up with this to provide seamless processing and results. Stock exchanges and Weather reports are some of the real-time examples.
3. VARIETY
- Structured Data
The set of data with a preset format, derived from a relational database. For example, an employee’s salary sheet with a predefined schema of things.

- Unstructured Data
These are random data without proper format or alignment. They require more processing time. Examples include Google searches, social media polls, Video streams.
- Semi-Structured Data
It is a combination of both Structured and Unstructured data. They have a proper structure yet lack the definition required.
How is Work Made Easier?
Before Big Data analytics came into existence, linear and a line-by-line analysis was done on the data available. Later with the introduction of computer life was made easy with Excel spreadsheets. The users needed to tabulate the different records and perform the required study to derive a meaningful report. Big Data analytics was a game changer in many different ways. Extensive data sets up to terabyte can be processed and analyzed. Complex queries and algorithms are applied. Reports are generated with a better outcome with almost zero failures. All these in a matter of minutes to hours depending on the size of data fed.
Top Companies Using Big Data Analytics
Big data analytics is employed in a wide variety of domains such as Manufacturing, Healthcare, Energy, Insurance, Sports, etc. Some of the top companies using Big Data analytics are listed below:
- IBM

- Target audience is identified.
Working With Big Data Analytics
With the help of third-party tools such as Hadoop, Spark we can load large data sets on to external storage. The data is processed based on the humanly written queries. The business intelligence team makes use of these reports to understand the predictive pattern and rectify previous mistakes. The data can be visualized to make useful decisions.
Advantages
- Business objectives can be understood completely.
- Learn the meaning behind numbers.
- Analyze the root causes of previous failures.
- Insights on future outcomes using easy-to-understand language.
- Contribute to making perfect decisions.
Pre-Requisites
There are no pre-requisites for using Big Data analytics. Basic knowledge of programming languages such as Java or Python would be helpful. Understanding how databases work and primal queries are sufficient. There are other High-level languages such as Spark, Pig that are easy to learn and use. The User should be technically sound in the way of using these to get the desired output.
Why Big Data Analytics is Used?
Big Data analytics is used to improve the applications and services to provide better outcomes. Various cost-efficient solutions can be derived. With the rapidly changing environment, it is essential to understand customer demands.
Scope of Big Data Analytics
Data analytics is never getting old fashioned and with the cutting edge technologies, it is increasing exponentially. There is a huge requirement for professionals in the field of Big Data Analytics. It is evolving with huge potential for growth. Data Analysts become the decision-makers of the companies with proper usage of Big Data technologies.
Need for Big Data Analytics
Nowadays data comes in different forms. Many of the analytical solutions were not possible in the past due to the cost of implementation and lack of professionals. With Big Data analytics are capable of performing complex algorithms on machine data within a time interval. These have many real-time use cases such as fraud-detection, targeting audience on a global platform, web advertising, etc.
Target Audience for Big Data Analytics
Organizations which make use of big data analytics and its components to achieve the following:
- Predict future trends and behavior patterns of customers.
- Analyze, understand and present data in useful ways.
