Great, Natasha!

PS:
– when the data is stored

Big Data is a massive volume of a variety set of data generated at a high velocity. It can yield important insights when the data is storage, processed and analyzed.

Hello Gisele! Great!!

Just a small correction here:

*information about clients

Have an excellent week!

Hi Augusto,

I understood, sometimes I made some mistakes, I´m trying to reduce it, anyway, thank you for all support that you give to me.

Have a nice Wednesday!

Very nice answer, Matheus.

Just some minor details:

– …this kind of tech (instead of “think”)
– it’s unquestionable that is has an incredible amount of information for all of us.

– Try to separate more the sentences, so it’ll be easier for the reader to absorb the content. For example:

…information for all of us.

Now, about trustworthiness, it is very difficult
(use the punctuation and skip a line).

Interesting video, big data is awesome to help us, not only in a specific sector but in all sectors across the world, think kind of tech has a massive potential to reduce cost, create new jobs and with this reduce many jobs as well, but it´s unquestionable which it´s has incredible veracity in undergoing information for all us, now, about the trustworthiness is very difficult because in my book has many hackers nowadays, it´s making very difficult for all we have trust in tecnologies, anyway, day by day the world is revolutionizing and we should live with it.

Have a nice day for all.

Absolutely, Sarah.

Some years ago one of my clients was a credit card company. I was amazing the amount of data these companies gather.

However, it was really hard to work with really large databases.

Let’s see what technology brings in translating data into quick and accurate information for decision-making.

Excellent comment, Augusto.

In the past, a lot of decisions in retail were based on feelings/assumptions/perceptions or based on limited data.

With Big Data it is possible to validate all these assumptions and come up with new solutions in the way products are positioned in a store to generate revenue increase, for example. Besides a lot of additional factors as you mentioned.
