Another Perfect Use Case for NoSQL
For MetLife the call for NoSQL was rooted in disparate data models across various acquired and organically developed product lines over a period of years. That led to disparate customer databases and the use of MongoDB to get a 360-degree view of all those customers -- a big, common problem. The Department of Defence use case explained here is another common scenario. Supply chains are invariably conglomerations of disparate commodity and part catalogs. Even vendors sellling the same goods have wildly different data models with unique numbering schemes, product descriptions and product dimensions and data.
I keep hearing NoSQL naysayers point out that NoSQL doesn't always make sense. That's certainly true, but the world is discovering that there are many use cases where it makes perfect sense.
