Gleaning insights from data is only one part of the data analysis process. Another fundamental part is telling a story with those insights to help inform better business decisions.  That’s where data visualization comes in.  As a data analyst, you can use charts, graphs, maps, and other visual representations of data to help present your findings in an easy-to-understand way.

Yes, job prospects are promising, as Ireland, as Europe's IT centre, provides several chances for data scientists. However, I would advise you to enrol at a reputable institution for your studies.

It's a great destination for studying for the following reasons:

1-    There are numerous tech companies in Ireland that provide adequate opportunities for someone with a background in computer engineering. Many big tech companies, such as Google, Facebook, Apple, and Microsoft, have a strong presence in the area, which helps to create a large number of top-level engineering employment.

2-    All of the major financial industry leaders are based in Ireland. Over 70 finance companies have their headquarters in Ireland. Many of them have software departments that employ a large number of students.

Data analysts take mountains of data and probe it to spot trends, make forecasts, and extract information to help their employers make better-informed business decisions. The career path you take as a data analyst depends in large part on your employer. Data analysts work on Wall Street at big investment banks, hedge funds, and private equity firms. 

They also work in the healthcare industry, marketing, and retail. In general, data analysts are everywhere. You can also find them at large insurance companies, credit bureaus, technology firms, and in almost any industry you can think of. Big tech companies such as Meta (formerly Facebook) and Google analyze big data to a dizzying degree. To do so, they employ many of the top data analysts for a variety of purposes including advertising and internal analysis along with a great deal of user analysis.

Data management refers to the practices of collecting, organizing, and storing data in a way that is efficient, secure, and cost effective. While some organizations will have roles dedicated to data management—data architects and engineers, database administrators, and information security analysts—data analysts often manage data in some capacity.
