The elegance of analytics systems and processes lies not in the gathering, storing and processing of data.  Today’s technology has made this relatively easy and common.  Rather it is in the integration and management to provide the highest quality data in…

Big Data still causes a lot of confusion in people's heads: What really is it? What is new and what is old wine in new bottles? In order to bring a little more clarity to the concept I thought it might help to describe the 4 key layers of a big data system - i.e. the different stages the data itself has to pass through on its journey from raw statistic or snippet of unstructured data (for example, social media post) to actionable insight.

Much of the explosion of big data has been driven by increased efficiency in sever performance, memory cost, distributed architecture improvements (cloud, and truly parallel databases, e.g. noSQL) and essentially, by how much it costs to process a terabyte of data, both in terms of memory and bandwidth resources.

However, most of the very big data is very sparse, from an…
