What is Big Data?

Big Data is an algorithm that deals with data science sets that are excessively large or complex and not easily computed with the traditional data-processing application software Available. Data with many rows have higher statistical power, whereas the data with higher levels of attributes or columns may lead to a higher Complexity Rate in the available data set. The big data concept includes several functions like capturing data, storage, analysis, searching data, sharing, transferring, visualizing, querying, updating timely, information privacy, and data source. 

Big data was actually Initiated with three key concepts: 

• Volume
• Variety
• Velocity 

When the user handles big data,  one cannot sample but they can simply observe and track the actions occurring in the processing mode. Thus, the big data concept is often used to include the data with sizes that exceed the capacity of ancient Software to process within the specific time and value.

Currently, the term big data is used to refer to the use of doing predictive and user behavior analytics, or certainly many other data analytics methods that extract value from data.

Relational database management systems also commonly known as RDBMS has software packages that are used to visualize data when it’s very difficult to handle big data.

Big data Science Course uses various sources such as mathematical analysis, optimization, statistics, and concepts from non-linear systems which helps to imply various concepts like regression Analysis, nonlinear and linear relationships, and causal effects from large data sets with a very low information density to reveal relationships and dependencies and it also helps to perform predictions of outcomes and their respective behaviors.

CHARACTERISTICS OF BIG DATA

Big data has specifically 3 following characteristics:

• VOLUME

The term Volume specifies the quantity of generated and stored data. The size of the data determines the value and potential counts, and whether it can be counted as a term of big data or not.

• VARIETY

This specifies the type and nature of the data. This helps people who analyze it to effectively use the resulting insight. Big data is drawn from text, images, audio, video; also it completes missing pieces with help of data fusion.

• VELOCITY

The velocity specifies the speed at which the data is generated and processed to meet the demands and challenges that lie in the path of growth and development. Big data is often available in real-time. Compared to small data, big data concepts are produced more continually. There are specifically two kinds of velocity related to big data is the frequency of generation and the frequency of handling, recording, and publishing.

• VERACITY

It is the external concept for big data, which refers to the data quality and the data value. The data quality of captured data may vary greatly, affecting accurate analysis.

Why Is Big Data Important?

Big data has its own importance which doesn’t revolve around the quantity of data you have, but what you do with it. You can collect data from any source and analyze it to find solutions that help in 

• Cost reductions
• Time reductions
• New product development and optimized offerings 
• Smart decision making. 

When the big data concept is combined with high-quality analytics, you can publish business-related tasks such as:

• Determining major causes of failures, issues occurring and defects in near-real time

• Generating coupons at the time of sale based on the customer’s buying habits

• Calculating entire risk portfolios in minutes again and again

• Detecting fraud/misleading behavior before it affects the organization

Mention few Use Cases of Big data

There are various use cases with the concept of Big Data but the most commonly known and used ones are mentioned below:

• Product Development

Companies like Netflix and (P&G) Procter & Gamble use big data to forecast customer demand. They build such predictive models for new products and services by classifying the key attributes of past and current products or services been used by customers and modeling the relationship between those attributes and the commercial success of the offerings. Also, P&G uses data and analytics from various groups, social media, test markets, and early store rollouts to plan, produce, and launch new products.

• Predictive Maintenance

Factors that can predict mechanical failures may be deeply buried in structured data, such as the year, make, and model of equipment, as well as in unstructured data that covers millions of log entries, sensor data, error messages, and engine temperature. By analyzing these indications of potential issues before the problems happen, organizations can deploy maintenance more cost-effectively and maximize parts and equipment uptime.

• Customer Experience

There is always a race between customers to grab the best deal available. A clearer view of customer experience is more possible now than ever before. Big data enables us to gather data from social media, web visits, call logs, and other sources to improve the experience and maximize the bundle of benefits being delivered. Start delivering personalized offers, reduce customer churn, and handle issues proactively.

• Fraud and Compliance

When it comes to security, it’s not just a few black hackers trying to steal the data from the website.

Security parameters and compliance requirements are constantly evolving. Big data helps you identify patterns in data that indicate fraud and monitor large volumes of information to make regulatory reporting much faster.

• Machine Learning

Machine learning is a rich topic right now. And specifically, big data is one of the reasons for it. We are now able to directly teach machines instead of program them of “How to perform a task”. The availability of big data to train AI learning models makes that possible.

Opt for the best machine learning online course to understand the topic and its working in detail.

• Operational Efficiency

Operational efficiency may not always make the buzz, but it’s an area in which big data is having the most impact. With big data, you can analyze and examine the production, customer feedback and returns, and other factors to reduce extras and forecast future demands. Big data can also be used to improve decision-making in line with current market demand.

How does Big Data Works??

Big data gives the user a new outlook that presents them up with new opportunities and business models. 

Big Data involves three key actions:

• Integrate

Big data recollects data from distinguishing sources and applications. Traditionally data integration mechanisms, such as extract, transform, and load generally aren’t up to the mark. It requires new mechanisms and technologies to analyze big data sets at terabytes, or even petabytes, scale.

During the integration process, you need to collect the data, assemble it, process it, and make sure it’s formatted and available in a form that your business analysts can use it as per the requirements.

• Manage

Big data requires a lot of storage. Your storage solution can lead you to cloud storage or on manual, or both. You can store your data in any form you want and bring your desired processing requirements and necessary process engines to those data sets on an on-demand basis. Many people choose their storage solution according to where their data is currently saved. The cloud is gradually gaining popularity because it supports your current manual requirements and enables you to access the resources whenever needed.

•  Analyze

The investment made by the user in big data pays off when you analyze and act on your data. Get new clarity with a visual analysis of your varied data sets. Explore the data further to make new discoveries. Share your findings with others. Build data models with machine learning and artificial intelligence. Put your data to work.

What Is Data Science?

Data Science is a mixture and combination of various tools, algorithms, and machine learning principles with the goal to find hidden patterns from the raw data.  

It also involves solving a problem in various ways to reach the solution and on the other hand,  it involves designing and construct new processes for data modeling and production using various prototypes, algorithms, predictive models, and custom analysis.
