We are living in a data-driven world. Our daily activities, like taking a ride in an Uber, surfing the net, social media interactions, gaming, etc. all contribute to data pools. Data is a valuable asset for businesses and companies are going the extra mile to have a robust team of big data experts.
The first step in the journey to be a specialist in any field is to familiarize yourself with the basics. So, let’s begin by understanding the different kinds of data that exist in the world.
Different forms of Data:
Structured data- This data can be organized in the form of tables, rows and columns. They can be easily accessed and operated. Examples of structured data are spreadsheets and the data stored in relational databases. Only 10% of the total data is structured.
Unstructured data- This data is neither structured nor organized. Operating unstructured data is quite difficult and requires advanced tools to access, sort and make sense out of this data. Examples are images, pdf files, video, streaming data, web content, email, graphics, etc.
The three ‘V’s of big data:
Volume- It denotes the total amount of data that is generated and stored. The units of measurement include gigabytes, terabytes and petabytes.
Variety- This denotes the different forms of data, namely structured, semi-structured and unstructured data.
Velocity- This is used for measuring the speed at which data is generated and processed.
Handling big data:
Hadoop is the best choice for dealing with complex data sets. It improves saleability of big data and enables users to play with data! Be it logs, json, xml or any other form of data- trust Hadoop to manage it.
It is equipped with a centralized processing system and an advanced tree structure for managing files. It allows parallel processing of large volumes of data.

The most ambitious project of India, Aadhaar project relies completely on Big Data. From collection of data to storage and utilization of biometric information of the entire population, big data till date has crossed over the billion mark. It is needless to say, a project of such a vast magnitude must be plagued with ample challenges but as its powered by big data, the chances of success is high.
Basically, Aadhaar is a unique 12 digit number assigned by the UIDA, Unique Identification Authority of India to an individual residing in India. The project was launched in the year 2009 under the supreme guidance of former Infosys CEO and co-founder Nandan Nilekani. He was the sole architect of this grand project, which required several added inputs from various other sources.
MapR, a business software company headquartered in California is providing technology support for the most-ambitious Aadhaar project. It is the developer-cum-distributer of “Apache APA +0.00% Hadoop” and for quite some time it is optimizing its well-integrated web-scale enterprise storage and real-time database tech for this project.
The encompassing technology architecture behind Aadhaar is structured on the principles of openness, strong security, linear scalability and vendor neutrality. The system is expected to expand with every new enrollment, which means it’s required to handle millions of transactions through billions of records, each day.

Are you too scared to even think that machines will fly away with your job?
Do you support that the rise of AI will make humans obsolete?
Nowadays, AI can perform a large number of tasks, right from managing insurance claims to handling investment portfolios to solving HR related stuffs. Amidst all, do humans stand a chance to fight against the Automation Apocalypse? If yes, then how?
As per 2016 reports, McKinsey analyzed 830 occupations and concluded that only 5% of them could be automated. Amazon also showed somewhat similar picture. Within 3 years, the number of robots operated by the company got increased from 1400 to 45000, which is quite a number, but the number of employees hired remained unchanged.
While Automation Apocalypse is raging a war in the tech world, majority of techies don’t feel the urgency of being scared for jobs. They don’t have any problem in learning new stuffs, which would eventually make them more tech-savvy.
AI will eventually make workforce of any organization more powerful. Machines make their jobs easier and that definitely work in favor of the company in question.
When computers were invented, did it eat away your jobs? No, so this time too, nothing like that is going to happen. Even, numerous surveys speak in favor of automation.
The post depression bedlam is clearing for developed nations. Nevertheless, the household debts are shooting up, making credit risk managers face growing default rates. As per the reports of International Finance, household debts have risen by USD 7.7 trillion since the year 2007 till 2015. At present, the debts stand at a whopping amount of USD 44 trillion – the figures can give anyone a nightmare!
In such a topsy-turvy situation, credit risk managers should look for ingenious methods to lower default rates and keep accuracy in check. Application of data analytics infused with Big Data can come to their rescue.
The term Big Data is really very big! Big Data can help draw crucial insights that would help financial institutions in analyzing their customer base and how their purchase decision patterns vary. It can also be used to enhance business results, especially in regard to credit risk management.
If you follow the current business news, in the coming three years, banks would be facing two major risks – Credit and Liquidity. However, if credit risk managers follow the below-mentioned ways, they can turn this complication into an opportunity:
- Data Analytics determines a person’s behavior and how his circumstances have changed. This is verified by his social media activity, which further affirms how his financial position has changed with time. Hence, the chances of fraud and non-repayment are put in check.
- With proper analysis of mobile and social media data, credit risk managers may be able to gather insights and broaden their market horizon, enhancing the market base.
- Data science can establish contact with low risk customers.
Parsing data with Python should always be discussed after getting a good grip on the nuances of machine learning because both the intricate concepts are interlaced with each other. Click on the link first pythonprogramming.net/downloads/intraQuarter.zip and then go forward with parsing the data.
The data set given in the above link resembles the data set we caught hold of when we first visited the webpages before. The point of interest here is that we don’t need to visit the page even. We just need to have the full HTML source code, that’s it! This system is quite similar to parsing the website without disturbing bandwidth use.
Things are not at all going right in the technological sphere. The domain is shrouded under the dark haze of WannaCry Ransomware this weekend. After the relaxing weekend, the Monday morning situation could never have been worse. The figures revealed on Monday evening by the Elliptic, a Bitcoin forensics firm, affirmed with the duty of keeping a close watch, confirmed a digit of $57,282, 23 shelled out to the hackers of Ransomware malware attack, who took over innumerable amount of computers worldwide on Friday and over the weekend.
The recent past has been witnessing the unprecedented malware attack across 150 countries. The current picture describes more than 200000 systems around the world being affected and the loss of tons of data.

A few years back also, Ransomware was unheard of and today it has emerged as one of the major issues of concern. So, what is the solution now? Several veteran data scientists and the honchos of the technological world have voted for Predictive Analysis as the ultimate solution for destroying Ransomware.
With the conventional cyber defense mechanisms at a backseat, Predictive Analysis defense technology remains the ultimate resort for any organization. The Predictive Analysis is mainly dependent on instituting a pattern of life within the enterprise and saving from disgruntling malware and similar disturbing activities.
Paul Brady, the CEO of Unitrends, explained the procedure where the backup system uses the tools of machine learning to identify and understand that certain data anomalies indicate the threat of a Ransomware attack.
So the above mentioned description clearly depicts the many advantages of Predictive Analysis. Now, the sad part of the story remains, that the difficulty in management remains the major blockage for the employment of this method. Let’s hope for the best and wait for the day when Predictive Analysis would be the only possible solution.
