Earlier companies were fine with storing the data into their servers because the volume of the data was less, and the amount of time to process this data was not much. But in today’s tech-savvy world companies are in desperate need to store and process big data. Big Data majorly comes from the following areas:
- Social media sites
- Sensor networks
- Cell phones
- Purchase transaction records
- Weblogs
- Medical records
- Military surveillance
- E-Commerce
- Complex scientific research and many more.
What is Big Data?
The collection of large and complex data sets that are difficult to store and process using traditional data processing applications are known as ‘Big Data’. This includes capturing, curating, searching, sharing, storing, transferring, analyzing and visualization of this data. But in this sense, any data can be said as big data. So, there are 5 V’s that contributes to major characteristics that define the big data as a whole:
1. VOLUME:
This is the most important characteristic that sets apart big data from other data sets. The ‘amount of data’ is known as volume. In today’s digitized world this volume is increasing at a very fast pace.
VELOCITY:
The pace at which different data is generated from various sources every day is known as velocity. Handling the rate of velocity will help in strategizing the daily work.
VARIETY:
There various types of data:
- Structured
- Semi-structured
VERACITY:
The inconsistency and incompleteness of data are known as veracity.
VALUE:
Turning this big data to some value is the most important for any company.
Examples of big data can be seen in many industries like:
- Walmart
- YouTube
- Amazon
They all stores, access, and analyzes millions of data that are generated by the user every day. Apart from them, mobile phones from all across the globe generate a lot of data as more than 5 billion people are calling, texting, tweeting and browsing. Also, modern cars have almost 100 sensors to monitor fuel level, tire pressure etc which in totality generates a lot of sensor data.
Mentioned below are various industries that make full use of Big Data application to become successful:
- Smarter Healthcare
- Retail
- Manufacturing
- Telecom
- Search Quality
- Traffic control
Now let’s understand as to why companies use Hadoop to handle their Big Data:
- Data Quality: The data is very inconsistent, messy and incomplete.
- Discovery: Discovering any new pattern from big data is very difficult.
- Storage: Big data can be very helpful if stored in a place which can easily scale up or down on-demand.
- Analytics: Analysing the variety of data can be very difficult.
- Security: Maintaining the confidentiality of such huge amount of data can be very tiring. It needs proper user authentication, restricting access based on a user, recording histories of data access, use of data encryption etc.
- Lack of Talent: There are not many people who are well aware of the usage of Big data. Companies are in desperate need for a team of developers, data scientists, and analysts who have a sufficient amount of domain knowledge.
All of this can easily be managed with the help of Hadoop software. A part of the Apache project sponsored by the Apache Software Foundation, Hadoop is an open-source programming framework. This supports the storage and processing of structured and unstructured large data sets in a distributed computing environment.
