What is Big Data Analytics? The Ultimate Guide for Beginners

If you’re not a data scientist, the term “big data analytics” might sound a bit intimidating. But it doesn’t have to be! In this guide, we’ll give you an overview of what big data analytics is and why it’s important. We’ll also cover some of the ways that businesses use this type of technology to solve problems more effectively. 

What is Big Data Analytics?

Big data analytics is a process that uses sophisticated algorithms to turn large datasets into actionable insights. It’s used to solve complex problems and make better decisions, which is why it’s also known as predictive analysis. 

Big data analytics has been around since the early 1990s, but its use has increased significantly since then due to the rise of big data technologies—like Hadoop—that make it easier for businesses to do more with their data. It can be applied in many industries, including healthcare, manufacturing, and retail.

History of Big Data Analytics

The term “big data” was first used in 1988, and it refers to the massive amount of data that companies produce. It has gained popularity over the years as technology has evolved, and the amount of information available has increased. Companies are now able to collect more data than ever before and analyze it for insights into their customers.

Big Data Analytics is a relatively new field that has emerged as a result of the rapid growth of data collection and storage. It started with the rise of the internet, which has led to an explosion in the amount of data available to analyze. With this boom came the demand for new ways to store, analyze and interpret large amounts of information. 

The term “Big Data” was first used by Blake Commagere at Microsoft in 2002 when he spoke about how companies were using large amounts of unstructured data from multiple sources for business purposes. He stated that this type of information could be analyzed using statistical modelling techniques such as regression analysis or clustering algorithms.

Types of Big Data Analytics

Big Data Analytics is a hot topic these days. Many companies are looking for ways to make use of the massive amount of data they have on hand, but they’re not sure where to begin. There are 3 basic types of big data analytics: descriptive, predictive, and prescriptive.

1. Descriptive Analytics

It involves analyzing past data to better understand trends in your business or industry. For example, if you’re a retailer with sales locations across multiple states and want to know where demand will be highest next holiday season so you can stock up on inventory accordingly, descriptive analytics can help you do just that!

2. Predictive Analytics

It uses historical data to predict future trends based on certain variables—for example, if our retailer wants to know whether they should open more locations in Texas next year, predictive analytics could tell them exactly where they should place those new stores.

3. Prescriptive Analytics

It goes one step further by using historical data to determine what changes should happen next—for example, if our retailer wants to know which of their existing locations should be expanded. 

Big Data Analytics Tools & Technology

1. Apache Hadoop

Apache Hadoop is a framework for the storage and processing of large volumes of data. It’s a distributed storage system that divides up the data into pieces, which are then stored on multiple machines in one or more locations (multi-data centre), and has applications process it on the fly as it comes back together again. 

The technologies within Hadoop include HDFS, MapReduce, Apache Hive, Apache Pig, and Apache Sqoop to name just a few.

Apache Hadoop’s role in big data analytics is primarily to provide an infrastructure for capturing and storing large amounts of unstructured data at scale. 

However, once captured and stored this way it can also be used directly by analysts as well as processed via other BI tools such as Tableau or Qlik View along with many others that are listed later on this page. 

2. Spark

Spark is a fast and general engine for large-scale data processing. It provides high-level APIs in Java, Scala, and Python, and an optimized engine that supports general execution graphs. Spark can process data up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk.

Spark is designed to be resilient against failure as well as scalable to run on thousands of nodes. It can run standalone or distributed across clusters of any size and architecture.

A Table represents a finite number of elements with typed columns (referred to as fields), where each element has a key associated with it.

4. Python and R Scripts

Python can be used to create complex models through its framework PyTorch or TensorFlow, while R has some frameworks such as ggplot2 which makes plotting much easier than in Python. 

You might choose one over the other depending on your use case; however, both are good enough tools for any kind of analytics project! 

5. Microsoft Azure (HDInsight)

Microsoft Azure (HDInsight) is a cloud-based big data analytics service. HDInsight is a Hadoop-based service, which means it can process large amounts of data stored in the Hadoop Distributed File System (HDFS).

Microsoft offers three different tiers of HDInsight: Standard, Premium, and Ultimate. Each tier has its features, capabilities, and pricing model.

HDInsight comes with built-in security features such as Kerberos authentication to secure your cluster nodes against unauthorized access attempts. 

6. Tableau BI Platform

Tableau BI Platform is a business intelligence (BI) tool that helps users visualize data. It has been used by many companies to create dashboards and reports. 

Why is Big Data Analytics Important?

Big Data Analytics allows companies to analyze large amounts of data quickly and efficiently so they can make better decisions about how they operate their business. But why is this important? Why should you care if a company uses Big Data Analytics? Here are just a few reasons:

How Does Big Data Analytics Works?

If you’re wondering how big data analytics works, you’re not alone. Many people are confused by the term and aren’t sure how it applies to them, but the truth is that big data analytics is a powerful tool that can be used in a variety of different ways. There are three main steps involved in big data analytics. 

1. Collection

This involves collecting all of your company’s data in one place so you can analyze it later. This can include information about customers, transactions, sales numbers, inventory levels, etc.

2. Analysis

Once information is collected, it’s time to analyze it! This means looking for specific trends in customer behavior or examining how certain products perform against each other in different markets. The aim is to identify relationships between different variables so you can come up with better ways to improve your business operations or products or services. 

3. Interpretation

Once you’ve identified those relationships between variables, it’s time for interpretation—figuring out what those correlations mean for your business going forward. 

Top 5 Uses of Big Data Analytics

Data analytics has become a critical part of the modern business landscape, and it’s not hard to see why. With so much data available, it’s important to know how to use it effectively. Here are some of the top uses of big data analytics:

top uses of big data analytics

1. Advertising

Big data can help advertisers target potential customers more accurately than ever before, allowing them to reach out through the channels that will resonate with those customers most strongly.

2. Customer Service

Big data allows companies to be more responsive when it comes to helping customers because they can see what their customers need and want immediately and take action on that information in real time. 

3. Marketing

Big data allows marketers to better understand their customers’ behavior by collecting and analyzing information from multiple sources—including social media posts, web browsing history, and even emails sent by consumers. 

This helps create more personalized marketing campaigns that resonate with specific audiences rather than trying to reach everyone at once with one message about your product or service offerings. 

4. Financial Analytics

Financial analytics helps businesses make better financial decisions by using data to analyze financial trends over time or across different industries or geographies. 

This kind of data analysis can help identify opportunities for growth as well as risks that could negatively affect profitability if not addressed properly early on before they become too large for smaller companies to overcome without heavy losses incurred by those involved along with additional expenses. 

5. Fraud Detection

Fraud detection uses big data analytics to identify irregular behaviour patterns that indicate potential fraud before it happens. 

Future of Big Data Analytics

The future of Big Data Analytics is bright. Big Data has been used for decades now, but it’s only recently that we’ve begun to understand its true potential. It is used to predict trends as well as create new ones. Big Data can help businesses make more accurate decisions about their products, services, and marketing strategies. We’ve seen some incredible things happen with the use of Big Data in recent years. 

Amazon was able to predict which books would sell well before they were published. This allowed them to invest more money into their authors’ careers and gain an edge over their competitors.

Netflix uses data analysis to determine which movies are going to be popular based on what people have already watched—and then they invest heavily in those projects so they’ll get a return on their investment when they’re released! 

Facebook uses machine learning algorithms to determine what kind of content each user wants to be based on what they like or comment on most often; this means they can tailor ads specifically towards those users’ interests and preferences, which helps them maximize ad revenue while also providing customers with relevant content that’s useful.
