What is Big Data? This term has become
popular recently, you can hear it
everywhere. But what does it generally mean? What does it need for? What benefits does it
give us? In this presentation, I’m going to answer these
questions and make a short introduction to the Big Data.
People for ages have collected data. Starting
from cave painting through papyruses, books, tapes to modern devices such
as discs. Along with it an amount of data has grown exponentially, so our
technologies have improved and now allow as to store a huge amount of data on
small and light devices. If we gathered all the data which had been collected
before the year 2000 it would be less, then we generate
now in 1 minute. The number of data roughly doubled every 40 months starting
from the 1980s. From 2012, every day has
generated 2.5 exabytes of data (exabyte 10^18). IDC predicts that we will have
gathered 163 zettabytes (zettabyte 10^21) of data till 2025.
Now the whole our life is digitalized. We
manage, share and store our lives online. Data gathers
from laptops, smartphones, social networks, online shops, search engines about
what we are doing. Moreover, a lot of things such as TVs, smart watches, and
other smart devices collect data. All this data has a different source,
structure, quality, variety. All these sources have a huge volume of
data. And all these sources have a tremendously high velocity of
collecting data.
So, how can we can manage, transfer, search,
visualize, query, analyze this data? This
is what Big Data is all about. Big Data describes data sets which are so
voluminous and complex that traditional data-processing software is not able to
deal with it. The words which are bolded in the previous paragraph describe 3
main concepts of Big Data: variety, volume, velocity.
The main reason to use Big Data is money. It
helps companies save money by providing business intelligence
that can spot losses, reduce the cost of inventory and operations. Big Data can
improve decision making by analyzing past data, to help
businesses make better decisions not only here and now but also forecast
future. It helps in analyzing users and customers’ feedback to improve
products and services.
Summarizing, Big Data is a
general name for constantly growing huge volumes of data. Also, Big
Data represents a wide range of software which is suited to work with such data, to bring profits to
companies and improve our lives.

For me as a programmer this is an area worth attention. There will be more projects based on Big Data in the future.
I think that it will be important to be aware about existing technologies and trends, but my prediction is that it will be so complicated that only qualified specialists will ever be able to comprehend everything.
As someone who works in IT industry, I think it is always good to have at least some basic knowledge about this area because in future it might come in handy, especially if you are a developer who wants to start a career in data science in the future.
I guess that because we are Every day going to improve our lives with technology, we will hevn't other choise, big date will be somthing what we will need to know, otherway life for us might be difficult.
It always depends. You can leave happily without knowing anything about it but on the other hand it might be helpful to know what data corporations may have on you and decide by yourself if you want them to have it or you'd prefer not to share that.
2. In terms of monetizing information technology skills, oh sure it does! But there is a catch, one must really feel the pleasure of data engineering and processing to stay in that field for a long time. It can be boring after working in this industry for some time.
Personally, I'm really interested in this topic and I would be willing to become a specialist in that field. Especially that there are so many case studies to focus on and to choose from. I don't think we could ever get bored of that, because of the variety that big data provides us.
So for me data is important and I believe we need to make huge adjustments in being more detailed in data collection.
2. I can’t imagine a scenario where financial analysts, marketing specialists, software engineers etc. would not have solid understanding of Big Data fundamentals, tools and techniques. It is one of the most crucial skills that every professional should have in order to stay competitive on the job market.
Definitely yes. Because computational power is growing, and every day there are more & more data collected. So for now, every digital and even traditional business collect as much data as they can, to better understand their clients.
2. Do you think it will be useful for you to be familiar with Big Data technologies?
I'm familiar with this technologies, and even have a diploma dedicated to machine learning, so I think it's useful for me.
Yes, it's definitely worth it. It is definitely a very cool technology that will continue to grow. Personally, I would like to learn it as soon as I have the time to do it.
Knowing how to work with it migh be a job opportunity for me in the future if i choose to deepen my knowledge in that direction.
For now im leaving it to the others.
I think that this amount of data will be useful for AI for better results in teaching process because sometimes we need some specific type of information for better results.
Actually the job market is full of offers for data scientists/ analyst and I think it is proper time to get into this topic, especially as an IT Specialist.
Connected wtih AI it can be very, very big step forward in Data Analyze.
Yes, of course and I am thinking about Data Science studies.
Could be, but I don’t really know. Data are often private or protected and because of that sometimes can’t be share with others.
Do you think it will be useful for you to be familiar with Big Data technologies?
I think yes, in future will be more and more data and somebody needs to take care of this. Also people need to be aware that sometimes data could be useful in context of future decisions.
I think that we can say that Big Data is "in-demand" now. It will be waste of time and resources if we don't use this now.
2. Do you think it will be useful for you to be familiar with Big Data technologies?
In my work I think that one day i will use Big Data. I think that in our generation (generation y and z) should expect that we will use this technologies.
It's even in demand right now. I know a lot of my friends that work in that field and they say it is a very lucrative and developing business. Due to data security information, it will become ever more valuable and with scarcer resources that the companies will have, they will have to learn how to analyze the data they have best they can, and that's what Big Data is for.
2. Do you think it will be useful for you to be familiar with Big Data technologies?
I think yes. My specialty is Data Science, so I expect to be dealing with Big Data quite often. It is exciting to think I could be seeing, e.g. patterns of clients' behaviours just out of the raw data and algorithms.
I'm not sure what did u mean by this question. I think it's useless for every day computer users. For the IT guys it depends on their profession. I don't need to know or learn any of the big data concepts in order to keep my job. Getting familiar with it and reaching a level to go to work would take quite much time. Looking at the job market I can say if they look for an IT guy doing Big Data, they usually look for experienced people. So if someone is interested then it is useful 'cause you get paid. Otherwise waste of time in my opinion.
Yes. It already is. A lot of companies are using it, and they're making a lot of money because of it.
2. Do you think it will be useful for you to be familiar with Big Data technologies?
Yes. Data have a lot of impact in our life. You can simply just check some things, that you need for example to work or education.
Do I think it will be useful for me to be familiar with Big Data technologies? I think everyone should know how does our favourite store know what we would like to buy. Of course I don't mean knowing technology behind it but rather being aware, that every our move in the internet is being watched for example by Google who then sell that data to our favourite store.
From my perspective - computer science student who is on the market for almost three years it obvious that I will face the wall of making complicated computations on big sets of data at some point. This segment of the market should actively evolve in the upcoming years since we have lots of sources of data.
I think that Big Data will be in entire IT world and it will be very hard to be IT specialist without meeting Big Data. In my opinion, a big part of new technologies will be relate with that because we need to store informations. To sum up, I hope that Big Data will be with me in the future.
