So what is big data?
Big data has been the feature of many articles in professional accounting journals such as CIMA’s Financial Management. But what exactly is big data? Originally it referred to more data than information systems could process. But today we have systems capable of processing and analysing millions of transactions in seconds . So what does it mean now? Well, I think the answer to this question will depend a lot on who you ask. To me big data is still data analytics, with maybe some external or social data sources thrown in., with a defined purpose of adding value or saving resources (such as cash or time). This is of course a very broad understanding of what big data is, as value will not mean the same thing to all organisations.
I read an article on Forbes recently which has a similar approach to big data as that I suggest above. The key point the author notes is not to care too much about defining things like big data, but to remember “who cares”. To quote directly from the article “the goal should be to solve a business problem by using new analytics, not to worry about defining a term. That’s because definitions are a distraction from the simple question of “Does this data contain information that is valuable for my business?”
