Information represents one of the greatest opportunities for modern business but there is a major barrier blocking the ability of organisations to deliver on that opportunity – the proliferation of fragmented business information solutions. Traditional approaches to overcoming this have focused on trying to force a single homogenised solution onto the business. This fails to recognise that it is often the local leverage of information which will deliver the most value. The Business Data Lake provides an opportunity to rationalise the data infrastructure while still retaining the local flexibility that ensures information works in the way the business needs.
