Large quantities of data, in any form (organized, semi-structured, unstructured, raw) are collectively referred to as “Big Data.” Data might be considered an asset while preparing a balance statement.
The huge volume, speed, and diversity of data assets required by Big Data, as described by Gartner, call for novel, cost-effective approaches to data processing to maximize insights and judgment. This has led to the widespread adoption of the 3 Vs of Big Data:
However, further studies have added two more aspects to the Big Data concept:
There are five key values to consider when working with big data.
- What is meant by “volume” is the total amount of information kept.
- Transferring information quickly is what we mean when we talk about transmission and reception speeds.
- There is a wide range of data formats and sources, including unstructured text documents, images, videos, emails, audio files, stock ticker data, and financial transactions.
- Inconsistency: The data flow is not always steady, and there may be periods of increased activity that make it difficult to manage data efficiently.
- When there is a lot of data from a lot of different places to manage, things get complicated.
Due to their size and complexity, the data sets pose significant challenges to conventional data processing tools. It is estimated that 2.5 quintillion bytes of data are created every day.
It’s estimated that 90% of all data ever produced has been made in the previous two years. It’s important to remember that over 80% of all data is unstructured; this includes data from weather sensors, social media postings, digital images and videos, transaction records, and mobile phone GPS, to name just a few examples.
Both the government and business sector have made use of Big Data to boost efficiency. Big data analytics were important in President Obama’s successful 2012 reelection campaign. Having seen the potential of Big Data to solve government issues, the Obama administration launched a research and development project focused on the field in 2012. The United States federal government is the proud owner of six of the world’s ten most powerful supercomputers.
Privately uploaded photographs are in the 50 billions, and Facebook employs Big Data to manage them. With Linux-based technology, Amazon.com handles millions of daily back-end activities. There are two data warehouses at eBay, one at 7.5 petabytes and another at 40 petabytes, plus a 40 petabyte Hadoop cluster for search. Over 2.1 billion credit card accounts are monitored by the FICO Falcon Credit Card Fraud Detection System.
With a database capacity of over 2.5 petabytes, Walmart is able to process over a million consumer transactions every hour. Estimates show that the volume of data in the world doubles every 1.2 years.
Role of Big Data in an Enterprise
Big Data database advancements have helped companies see the significance of data to their growth and success. These databases have helped companies cut costs, boost profits, and do much more. Finding the one piece of information that will give your company an edge over the competition is the true problem. Hadoop is helpful for managing and processing massive data sets. It also helps with reshaping data into a more workable shape and format, and with mining it for insights.
Big Data in International Development
Big data is useful for more than just IT firms and can be implemented across many sectors. The Research on Effective Uses of Information and Communication Technologies for Development (ICT4D) suggests that Big Data technologies may be very helpful and make substantial contributions to resolving difficulties in international development. Improvements in decision-making in crucial areas of development including healthcare, employment, law and crime, security, natural catastrophes, and so on are made possible by advances in Big Data technology.
Big Data Job Opportunities
Jobs in the IT sector are plentiful for anyone with the necessary skills, and Big Data is a key driver of this trend. McKinsey & Company predicted in 2011 that the United States might soon experience a critical shortage of analysts with expertise in big data. Businesses are constantly on the lookout for qualified workers who can help them reap the benefits of Big Data’s potential to provide them a strategic edge. Experts are needed for a variety of Big Data tasks.
1. Chief Data Officer
An organization will have one person responsible for leading the push in putting Big Data into action. He or she plays a pivotal role in the company. He or she must be a member of the company’s executive board and report directly to the chief executive officer.
2. Big Data Engineer
There is a significant need for engineers skilled in creating, maintaining, testing, and assessing solutions for Big Data. A strong command of Java, C++, PHP, Ruby, Python, and other equivalent programming and scripting languages is required. The ability to construct Hadoop and Hive-based data processing systems is another crucial talent he should have.
With this in mind, it’s safe to say that Big Data is gaining popularity in today’s technologically advanced society, with more and more companies investing in it to save costs and increase productivity.
3. Data Scientist
This is going to be one of the hottest careers of the 21st century. As the fields of Big Data and Data Science expand at a dizzying rate, the need for skilled Data Scientists is greater than ever. However, this is not a child’s play. A good Data Scientist will have mastered a wide range of techniques, including but not limited to natural learning processes, machine learning, conceptual modeling, statistical analysis, predictive modeling, and hypothetical testing.
If you want to make it as a Data Scientist, you’ll need to master these other talents as well:
- Possess the capacity to construct program databases Fluent in both written and vocal communication Effective in a fast-paced, multi-disciplinary workplace
- The capacity to conduct statistical analysis and query databases
- Abilities to show and set an example
- Competence in working without direct supervision
- The fundamentals of design and construction are well-understood.
4. Big Data Analyst
For the Data Scientist to succeed, a Big Data Analyst’s help is essential. Working with data in a system and evaluating different data sets are two of his main tasks. A Big Data Analyst may find work as a Data Scientist in the near future. Accordingly, he’ll need to possess comparable talents and expertise. Expertise in advanced modeling approaches, testing, data creation, and reporting in plain English are all necessary. Skill in testing is essential for every Big Data Analyst who hopes to achieve success in the analysis of databases. A Big Data Analyst’s success depends on his or her ability to effectively convey complex concepts and findings to others.
5. Big Data Visualizer
6. Big Data Manager
The Big Data Manager’s role is to bridge the gap between the technical staff and upper-level management. Manager of Data Science, Big Data Analysts, and Big Data Visualizers. He or she must master core management skills such as communicating effectively and efficiently, forming personal relationships with the Big Data team, adapting to changing environments, and understanding, interpreting, and relating the organization’s strategy to the team.
7. Big Data Solutions Architect
In this field, we address problems and needs unique to Big Data. Big Data Solutions Architects are crucial to any business because of the expertise they provide in detailing the inner workings of a Big Data solution. For him, knowing Hadoop is an absolute need. The skillset of a Big Data Solutions Architect should include the following, but is not limited to them: strong written and verbal communication skills; the ability to clearly articulate the benefits and drawbacks of various technologies; the ability to document used cases, solutions, and recommendations; the ability to work independently and as part of a team; and so on.
