What Is Big Data?
Big data refers to any mass of unstructured, complex information that exceeds traditional database management systems' handling capability. Data of this magnitude cannot be managed or processed using traditional database management applications or data processing software.
What sources are this data? What contribution have we made towards such vast collections of data?
Sources Of Big Data
Data available on Earth continues to expand exponentially as humans generate it through daily activities and various sources. Internet, mobile phones, and IoT have connected us worldwide; every decision leaves its digital trail behind.
Whenever you access an app on your mobile phone, sign up on a website, visit a webpage, or type keywords into search engines, some data is collected about you. Imagine this scenario. In our browser, we typed in "Big Data". After clicking on this article's link, we see its sheer volume of information. Imagine people spending their free time online: visiting various websites, uploading images, and more - this vast amounts to an immense amount of data that requires storage space for processing and analysis.
Primary data sources are mobile phones, social media platforms and websites, digital images, videos, and sensor networks; purchase transaction records, medical files, eCommerce systems, military surveillance systems, medical records, and scientific research are also important sources.
It would take approximately Quintillion Bytes of data storage space for all this to exist, and 40 Zettabytes would be generated each year, which equates to multiplying every grain of sand on Earth by 75 times!
Big Data Types
Big data comes in three distinct forms: Structured, Semistructured, and Unstructured. Let us now examine these forms and their examples in more depth.
1. Semistructured
Semistructured data refers to information that does not follow an ordered list like RDBMS tables; instead, it uses organizational properties like tags or markers for the separability of semantic elements, thereby making analysis more straightforward.
2. Unstructured
RDBMS cannot store unstructured data as it lacks form or structure; such unstructured information can only be adequately analyzed once converted to a structured format; over 80% of organizationally generated information falls into this category.
3. Structures
Structured data refers to information that is quickly processed, stored, and accessed using standard formats for processing, storage, and accessing purposes. Structured data has an easily manageable structure with a predetermined schema that makes processing straightforward; SQL can help manage structured data effectively.
5 V's Of Big Data
The 5 Vs. are Volume, Variety, Velocity and Value. These are the Big Data Characteristics .
1. Volume
Volume is defined as the daily accumulation of data. Volume helps define whether we classify certain sets as big data; "Volume" ranks highly when dealing with Big Data.
2. Velocity
Velocity is the rate at which massive volumes of data are created from various sources daily and constantly flowing into society.
Facebook DAU Mobile now has approximately 1.03 billion Daily Active Users, an increase of 22% year over year and evidence that social media use and data collection continues at an incredible pace. This shows how fast its growth is taking hold across platforms like mobile.
Real-time data allows us to gain insights and make decisions in moments, provided we can handle its speed.
3. Variety
Variety refers to data generated from diverse sources in its various forms; semistructured, unstructured, and structured forms all fall under this definition.
Data used to be contained solely within Excel or databases; now, it may come in forms such as pictures, audio/videos/PDFs, etc, and create issues when storing, mining, and extracting it for insight.
4. Veracity
Data inconsistency, incompleteness, and integrity contribute to data uncertainty; organizations must consider this when dealing with Big Data.
5. You Can Also Value
Data without analysis lacks value and must be converted to something usable for its full benefits to become apparent. Simply gathering and storing vast volumes of raw information has no meaning or use; until its analyses occur, it's simply gathering dust.

Big Data Challenges
1. Data Growth
Finding insights within rapidly increasing data can be challenging; finding relevant data amidst vast quantities produced every second can be impossible.
2. Data Storage
Organizations need help managing and storing vast volumes of data. Reliable storage solutions must be in place to do so effectively and flexibly.
3. Data Quality
Data created by organizations often needs to be more coherent, complete, and organized - making its management even more complicated than expected. Companies in the US alone lose about $600 billion every year because of flawed or inconsistent information.
4. You Can Also Read About The Advantages Of Using It.
Organizations often need more awareness of what data exists within their system, making data analysis challenging.
5. The Security Of Your Own Home
Organizations face the daunting challenge of safeguarding all the information within their possession from advanced persistent threats that seek to compromise it through authentication, authorization, encryption, etc. To keep data safe, they enlist authentication services such as OATH to authenticate users before authorizing access and encryption of data, etc.
6. Miscellaneous Challenges
Big data presents numerous difficulties that must be navigated successfully, from talent availability and integration issues, cost concerns, and accuracy issues, all the way up to timely processing requirements and timely processing requirements.
