What is big data?
Put simply, big data is a large data set (who’d have guessed?). It’s usually too complicated for your typical data processing applications to handle and it comes with loads of challenges with managing it.
The key to big data isn’t the quantity of data available, but more how companies use it. If it’s used correctly, it can give companies some valuable insight into their potential customers and help them develop their products.
What is data analytics?
Data analytics is how companies manage the data they have. It includes extracting and analysing it to gain insight, draw conclusions and create actionable tasks. It doesn’t have to be the analysis of big data, though. It can apply to the processing of any kind of data, big or small.
