Big Data & Analytics

Big Data: Big Data refers to humongous volumes of data that cannot be processed effectively with the traditional applications that exist. The processing of Big Data begins with the raw data that isn't aggregated and is most often impossible to store in the memory of a single computer.
A buzzword that is used to describe immense volumes of data, both unstructured and structured, Big Data inundates a business on a day-to-day basis. Big Data is something that can be used to analyze insights which can lead to better decisions and strategic business moves.
The definition of Big Data, given by Gartner is, Big data is high-volume, and high-velocity and/or high-variety information assets that demand cost-effective, innovative forms of information processing that enable enhanced insight, decision making, and process automation.
Data Analytics: Data Analytics the science of examining raw data with the purpose of drawing conclusions about that information.
Data Analytics involves applying an algorithmic or mechanical process to derive insights. For example, running through a number of data sets to look for meaningful correlations between each other.
It is used in a number of industries to allow the organizations and companies to make better decisions as well as verify and disprove existing theories or models.
The focus of Data Analytics lies in inference, which is the process of deriving conclusions that are solely based on what the researcher already knows.

It's a huge market with very few people who are proficient in the same. You can read this article on Forbes which lists out the reasons to why Data Science is a great career option.

You Should go to Ireland because-
English languageAlthough Irish Gaelic is recognised as the first official language of the country, only 36% of the Irish population actually know it. 94% of the population know English, with it being the second official language. The Irish accent and dialect may be a little overwhelming at first, but you will soon get used to it. Living, studying, and working in Ireland is a great way to improve your speaking and listening ability in English. Post study visa
One of the major benefits of studying in Ireland is the post-study visa. This makes it easier for students to look for job opportunities in the country after they graduate, and once they have a job, they are then eligible to apply for a green card/work permit. In addition, the Irish government has also agreed to extend the stay back option to two years from one year for non-EU/EEA students who study at level 9 or above in the national framework. Why Not UKHow easy is it for international students to work in the UK? For non-EU students, the rules on moving from a student visa to a work visa are pretty strict. Essentially youve got to have a graduate job, with a graduate salary, with a licensed Home Office employer. These criteria are hard to meet. For starters, the graduate salary needs to be a minimum of 20,800, which for a first job is pretty difficult, especially outside of London. We had a student with an M.Sc. In marketing who was offered a job with a top firm as a marketing assistant. But that is not a graduate job youve got to be a marketing manager, explains Scott. And you cant just work for a little tech company down in Hackney. Currently, non-EU students can work part time for 20 hours a week and full time in vacations. If they go to a private college, there not allowed to work at all. This was one of the measures introduced last year in a Home Office crackdown on visa fraud, targeting students at bogus private colleges.
