Thank you very much for your lectures , I have tried online Learning and paid for lectures two years ago but I didn’t understand this book fully so I have never tried to do it again. Your teaching is very easy to understand , you are a very good teacher. I have my exam booked for next week so I will give it a try and see how it goes.
Thank you very much again ?

Thank you for all the free lectures, John. Finished watching them just now and will be sitting the exam next month. Your videos and notes have been really useful for understanding the concepts 🙂

Thank you so much for all your lectures John.
Any info on when the lecture on big data will be uploaded?
October 27, 2022 at 4:42 pm
Sorry but I just have not had the time yet.
However there are no calculations involved so reading the chapter in our notes is sufficient (and asking in the Ask the Tutor Forum if there is anything in the chapter that you are not clear about).

Hi John, when well we have a lecture on “BIg data”? also in this lecture i couldn’t find the notion of “loyalty card system” does it refers to data collected by the companies(through loyalty cards) in order to later process them? as always thank YOU

i just found found the “loyalty cards” in the next lectures notes

Did the tutor swear at 8:20?! Lol!!!

I really appreciated the exposure to the loyalty card system, with an amazing explanation you delivered.
However, I would like to raise a question – supermarkets more to more might have thousands of customers if they are a chain of supermarkets. Are you telling me that a single high capacity computer or a few computer database servers are not enough to handle data for a few thousand customers, and loyalty programs are thus considered Big Data?
Please help clarify.

Because according to the definition of big data, they are data so large that the conventional methods of storing and processing wont work. I think any good quality computer or a few of them, could easily manage data on a few thousand customers of a supermarket.

In future, please ask questions like this in the Ask the Tutor Forum and not as a comment on a lecture.
What you have written is not a definition of Big Data and is a minor point for answers in the exam. However a chain of supermarkets will have thousands of customers a day and will not just be recording what the customers buy, but how they pay, what times of day they usually visit etc. etc.. All of this data needs to be stored and, more importantly, needs software searching for any relationships and producing information instantly. For example, the supermarket I use regularly obviously knows the days I tend to shop and automatically sends me an email the day before highlighting special offers on items that it knows I regularly buy. It also knows my age, my credit card details, details of the members of my family, etc. etc.. All of this will certainly need investment in more than simply a single high capacity computer, and will need special software that can look for relationships that cannot always be predicted in advance between different data and can produce information instantly.

I got the definition from Ch22 Pg88, of your Notes:
“ In addition, many definitions also state that the data sets are so large that conventional methods of storing and processing the data will not work.”
Secondly, I stated my question below this lecture because the question was relevant to points made in the very same lecture. It was not a random question- you explain loyalty program within this lecture. Are we allowed to post only comments below lectures , and defer all questions related to any doubts raised from the lecture to the AsktheTutor forum instead ? Please clarify.
Thankyou for the explanations.

I was just confounded because all data what you say the loyalty program records, are text info, which should only require kilobytes or max mega bites of storage perhaps? And a database software installed which might be some gb, should be able to analyse it ? So thats why I thought a high capacity computer which can store Terabytes should be enough. Am I missing the big picture ? Please support.

I do not always see questions posted here, and here is not a place to have a prolonged discussion. That is what the Ask the Tutor Forums are for.
The power of the computer needed is a minor issue. It is just a fact that because of the amount of data being held, the algorithms needed to identify relationships that are not known of in advance, and the speed necessary will inevitably need a much more powerful computer than a normal desktop. However the exam is interested in what is meant by Big Data and the uses of it, which are more more than conventional databases that have existed for ages.
