Think of how storing information has evolved over the years: first we had the rolodex (or as some of you might remember- the carousel) and today we have cloud storage, like Dropbox. As the years went by, we continued to improve the way we store important information.
So now what about big corporations and their colossal amounts of data? How has technology evolved so that it stores such private information securely? Well, in 1970, the term data warehousing was coined.
It is the one solution to categorising and storing an abundance of statistics, facts and numbers safely out of reach of those who do not have permission to login.
