Although, you could argue that the business use defines the technology use case which, in turn, informs the decision to use "nosql". For example, key/value DB's have enabled me to better implement features of a enterprise web app I am working on. The lack of a defined schema, in particular, was a strong business case for deciding to use key/value DB's. This document-based app can now store arbitrary fields on a per user basis (which was a headache with SQL!), which is a key USP for the app. Although, I agree, these points are tech-related. It would be nice to see the article mention true business use cases, such as transactions (i.e for financial, sensitive data applications).
