Big data is a term that describes the massive amount of data that is available to organizations and individuals from various sources and devices 📱. This data is so large and complex that traditional data processing tools cannot handle it easily 💥.
But how can we define and measure big data? What are the main characteristics of big data that make it different from typical data? How can we use big data to solve problems and create value? In this article, we will explore the 5 V's of big data: volume, velocity, variety, veracity, and value 🚀.
We will also look at some examples of big data types and tools that can help us deal with the 5 V's of big data 🔥.
Types of Big Data 🌈
Before we dive into the 5 V's of big data, let's first understand the different types and formats of big data that exist and are collected by organizations or individuals 🎧.
Big data can be classified into three main types: structured, semi-structured, or unstructured data 📄.
Structured Data 💎
Structured data is data that is easily formatted and stored in relational databases, such as numbers, dates, or text. Structured data has a predefined schema and structure that can be queried using SQL (Structured Query Language) 💯.
For example, customer records, sales transactions, product inventory, or bank accounts are examples of structured data that can be stored in tables with rows and columns ✨.
Semi-Structured Data 🌟
Semi-structured data is data that is partially formatted and stored in non-relational databases, such as JSON or XML files. Semi-structured data has some elements of structure, such as tags or keys, but does not follow a rigid schema or structure 🔮.
For example, web logs, social media posts, email messages, or sensor data are examples of semi-structured data that can be stored in files with key-value pairs or nested objects 💫.
Unstructured Data 💫
Unstructured data is data that is free-form and less quantifiable, such as text, audio, video, or images. Unstructured data does not have a predefined schema or structure and cannot be easily queried using SQL 🔥.
For example,
documents,
books,
articles,
podcasts,
videos,
or photos are examples of unstructured
data that can be stored in files
or folders 💡.
5 V's of Big Data 🔥
Now that we know the different types
of big
data,
let's look at the 5 V's
of big
data:
volume,
velocity,
variety,
veracity,
and value 🚀.
These are the five main
and innate characteristics
of big
data that define
and measure it 🔎.
Volume: The Size of Big Data 📏
Volume is the first
and most obvious characteristic
of big
data.
It refers to the amount
of data that exists
and is collected by organizations
or individuals 💾.
Big
data is measured in terms
of petabytes (more than 1 million gigabytes)
or exabytes (more than 1 billion gigabytes)
of data,
as opposed to the gigabytes common for personal devices 🌟.
The volume
of big
data is growing exponentially due to the increasing number
of devices
and sources that generate
and capture data,
such as smartphones,
sensors,
social media,
web pages,
and more 🌐.
The volume
of big
data can be a challenge for traditional systems
and tools that have limited storage
and processing capacity 🙅♂️.
However,
it can also be an opportunity for organizations
and individuals
that can leverage big
data to gain insights
and create value 💯.
For example,
Facebook users upload at least 14.58 million photos per hour.
Each photo garners interactions stored along with it,
such as likes and comments.
Users have “liked” at least a trillion posts,
comments,
and other data points.
This huge volume of data helps Facebook to understand its users better and provide them with personalized recommendations and ads 💰.
Velocity: The Speed of Big Data ⏱️
Velocity is the second characteristic of big data. It refers to how quickly data is generated and collected by organizations or individuals ⚡️.
Big data is often generated and collected at a fast rate, often in real time or near real time. This means that big data is constantly flowing and changing 🌊.
The velocity of big data can be a challenge for traditional systems and tools that have limited processing and analysis speed 🙅♀️. However, it can also be an opportunity for organizations and individuals that can use big data to make timely and informed decisions 💡.
For example,
there are more than 3.5 billion searches per day are made on Google.
Google uses big data to provide relevant and accurate results to its users in milliseconds ⚡️.
Variety: The Types of Big Data 🌈
Variety is the third characteristic of big data. It refers to the types and formats of data that exist and are collected by organizations or individuals 🎧.
As we saw earlier, big data can be classified into three main types: structured, semi-structured, or unstructured data 📄.
The variety of big data can be a challenge for traditional systems and tools that have limited flexibility and functionality to handle different types of data 🙅♂️. However, it can also be an opportunity for organizations and individuals that can use big data to discover new patterns and trends 💯.
For example,
Netflix uses big data to recommend movies and shows to its users based on their viewing history 🎥.
Netflix collects and analyzes various types of data,
such as ratings,
reviews,
genres,
actors,
directors,
subtitles,
and more 🌟.
This helps Netflix to provide personalized and relevant content to its users 💰.
Veracity: The Quality of Big Data 🔎
Veracity is the fourth characteristic of big data. It refers to the quality and reliability of data that exist and are collected by organizations or individuals 🧐.
Big data can have different levels of quality and reliability depending on its source, context, purpose, and meaning 🔥.
Some sources of big data can be more trustworthy than others, such as official records versus social media posts 💯.
Some contexts of big data can be more relevant than others, such as current events versus historical events ✨.
Some purposes of big data can be more specific than others,
such as research questions versus general queries 🔮.
Some meanings of big
data can be more clear than others,
such as facts versus opinions 💡.
The veracity of big
data can be a challenge for traditional systems
and tools that have limited accuracy
and consistency to validate
and verify
data 🙅♀️.
However,
it can also be an opportunity for organizations
and individuals
that can use big
data to improve
the quality
and reliability
of their decisions 💯.
For example,
Google uses big data to predict flu outbreaks based on search queries 🤒.
Google analyzes millions of search queries related to flu symptoms and locations 🌐.
Google validates and verifies the data using official sources such as the Centers for Disease Control and Prevention (CDC) 💯.
This helps Google to provide accurate and timely information to the public and health authorities 💰.
Value: The Benefit of Big Data 💰
Value is the fifth
and final characteristic
of big
data.
It refers to the benefit
and impact
of data
that exist
and are collected by organizations
or individuals 💰.
Big
data has intrinsic value,
but it needs to be extracted
and transformed into something useful
to create value 💎.
Big
data can create value
by providing insights,
solutions,
innovations,
predictions,
and social good 🔮.
The value
of big
data can be a challenge for traditional systems
and tools that have limited functionality
and interoperability to analyze
and visualize
data 🙅♂️.
However,
it can also be an opportunity for organizations
and individuals
that can use big
data to enhance their performance,
competitiveness,
and customer satisfaction 💯.
For example,
UNICEF uses big data to monitor child well-being indicators such as education, health, nutrition, protection, and more 👶.
UNICEF collects and analyzes various types of data from different sources such as surveys, reports, social media, satellite images, and more 🌟.
UNICEF transforms the data into actionable insights and evidence-based solutions 🔮.
This helps UNICEF to improve the lives of children around the world 💰.
