The Advantages of Learning Fintech

In any market, when a certain industrial product or service is launched, there are a variety of reasons why it may work or may not work for the industry. This holds especially true in terms of any of the new technologies entering the market. The growth of such technological industries determines the influx of new players, some of whom may come in with a silver spoon in their mouths, basically turning everything they touch into gold, great turnovers, fabulous mergers and acquisitions and so on. At the same time, there are also a number of failures and flounders in the industry.

Also Read: Introduction to Fintech

The fintech industry is not a very new one and has been through its fair share of ups and downs. In spite of a little while of a slump in the middle, there are many ways in which the fintech industry has strived and turned its trade positive in order to come to be thriving in the present times. One of the main reason why this industry has seen more ups is that it catered not just to the big guns but also to the small business owners which included all the disadvantaged sections of the society, women, minorities and immigrants.

This industry is going to grow on and be stronger, which is why there are many experts who believe it is advantageous to get certified and get into this industry.

 

Here are a few reasons why we believe there are great advantages in learning Fintech;

  1. Financial technology has been criticised in the sense that it would not see a large number of growth and developments in the future. But the majority thinks otherwise. The reason that fintech is actually going to be there in the industry for a much longer time is the very fact that banks are getting digitalized and they are doing so at an alarmingly fast rate. The industry is no longer at the innovator stage and is more at an adoption stage. Thus getting certified to work in this industry will prove extremely advantageous.
  2. Fintech companies or those organizations that are involved in this industry don’t really have the rules of capitalism apply to them. This is mainly because of the fact that, in capitalism, there is the chance of companies getting explosive dividends and later on also going bust. But in case of fintech whenever a void is created, there would be a number of alternative lenders to jump in to fill it up. This is the reason why the field of fintech which does not follow a ‘growth at all costs’ mentality will definitely flourish both in terms of growth and job opportunities.
  3. The world is getting digitalized on a massive scale and today no one really has any time for actually getting their transactions done from slower, larger financial corporations anymore. Technology has touched every single sphere of life including the sphere of banking. This is why learning the various nuances of fintech would be most definitely an advantage for candidates entering into this new world of technology.

The above reasons are why learning fintech is a great option for candidates looking to get into the industry today.

Big Data Soon To Cure Infectious Diseases

big data in Healthcare

2016 has seen a massive spurt of popularity for the field of Big Data Science. With concepts like Artificial Intelligence and predictive analytics, coming into the limelight, the whole world experienced the dawn of a new era in terms of the field of information technology. We are all aware of the various marvels that can be performed with the help of data analytics. Some very popular examples could be the growth and development in Artificial Intelligence, the various employee enhancements strategies of the Human Resources Departments, the fact that the entire world could be going cashless soon enough and so on. But did you know, that big data is now can be advanced enough in healthcare industry, to stop and fight infectious diseases?

big-data-healthcareEarlier in the early, post modern times, it was a huge task to be able to track any kind of disease at all. Probably this was why there were a majority of outbreaks of epidemic diseases. Medical information was either unavailable or there was no medium through which it could be kept a track of. With the advent of technology it became very possible to store huge amounts of medical records on the PC’s. But then, as there was no way to connect countries wirelessly, it was impossible to inform everyone about certain outbreaks. This was because you would have to print every single piece of information and then take the pains of actually going ahead and transferring it to different quarters. But with the advent of the internet and now with the advent of Big Data Science, the scene has changed drastically. What earlier seemed a fable like thought, today seems a possible reality. With the help of various data analytics tools today, it is soon going to be possible to map various diseases, their impact as well as, make it possible for asserting predictions.

healthcare and Big DataOutbreaks are usually found in places with high chances of exposure, like for example hospitals or places with a large number of infected people. Big data would be able to track such occurrences, which are also known as “healthcare associated infections”, the benefit of which will help us then map the spread of such diseases. While on one hand, it was difficult to map these diseases in the early days, mainly because of the fact, that with time they changed as well. But today, with the concept of evolving maps in place, in addition to being interactive, these can map the progress as well as intensity of the diseases. These diseases are usually known to make rapid shifts in terms of how it spreads and where it spreads to, this is where the maps will be able to serves perfectly, mainly because this will help professionals to go on and predict of the next place, that the disease might affect, thus in a way forewarning. There are many efforts being taken to develop such data simulation systems by a number of Data Scientists. This is another reason why the field of Big Data Science has begun to attract more aspirants.

Why Hadoop?

The term “big data” certainly isn’t just referring to the mounting volumes of information companies are collecting. It is just as much about the variety and velocity matters i.e. the massive amounts of unstructured data that needs to be stored, managed, cleaned and then dashed around to talk to other data or move in near real-time.
One cannot overlook the issue of volume. Estimates contend that financial and securities organizations are juggling around 3.8 petabytes per firm. Following behind the investment institutions, the banking industry is contending with around 1.9 petabytes.
The variety and need for speed on this data is the real crux of the issue—and big banks are starting to see clearer paths as they look to advanced analytics platforms outside of the traditional databases as well as to frameworks like Hadoop.
To put the real challenges in some context, we take a look at a few examples of large financial and banking institutions that are hitting the upper limits of their traditional systems and looking beyond to new analytics and framework solutions.

Morgan Stanley’s Big Data Approach

As one of the largest global financial services organizations in the world with over $300 billion in assets under its care, Morgan Stanley keeps close tabs on new frameworks and tools to manage the complex information pools that back high-stakes decisions.
The financial services giant has been vocal about how it is solving the challenges of the industry, most recently by looking to the Hadoop framework.
The limitations of the traditional databases and grid computing paradigms that served the financial giant for years were stretched to the limit.
Like several other investment banks, Morgan Stanley started to look to Hadoop as the framework of choice to support growing data size, but more importantly, data complexity and the need for solid speed. The adoption of Hadoop allowed Morgan Stanley to “bring really cheap infrastructure into a framework” that let them install Hadoop and let it handle the tasks.
The company now has a “very scalable solution for portfolio analysis. At the core of the Hadoop future at Morgan Stanley is the matter of scalability. It allows management of petabytes of data, which is unheard of in the traditional database world.

Bank of America Tackles Big Data

As one of the largest banks in the States, Bank of America has been in good company with others of the same ilk that are seeking to tap into Hadoop to manage large amounts of transaction and customer data.
Big data will create a new era for businesses of all types, spawning a “second Industrial Revolution” which will be driven by open source frameworks, including Hadoop which has the potential to be as disruptive as Linux was 20 years ago.
Hadoop enables the bank to be good custodians of cash, & increase transparency & in the larger system to drive positive change.
Hadoop in finance has fast emerged as the preferred choice for financial big data as Hadoop financial analysis has the following advantages:

  1. Segregation of data and computation to save network bandwidth and faster calculations
  2. Financial big data requires performing thousands and millions of calculations in a matter of seconds. Traditional solutions import data over the server which causes unnecessary bottlenecks over the network and interferes with other processes
  3. Hadoop in finance can be leveraged to perform calculations locally and use the network only for transmitting the results which saves precious network space for more important processes.

The differentiator that Hadoop brings is by enabling doing the same things on a much larger scale and gets better results.
To sum it up, Hadoop and Big Data in financial services has been acknowledged by world’s leading financial institutions as the way for the future.
