NoSQL matters Conference in Cologne, Germany 2013 - NoSQL Distilled to an hour by Martin Fowler - http://2013.nosql-matters.org/cgn/ NoSQL databases offer a significant change to how enterprise applications are built, challenging to two-decade hegemony of relational databases. The question people face is whether NoSQL databases are an appropriate choice, either for new projects or to introduce to existing projects. I'll give rapid introduction to NoSQL databases: where they came from, the nature of the data models they use, and the different way you have to think about consistency. From this I'll outline what kinds of circumstances you should consider using them, why they will not make relational databases obsolete, and the important consequence of polyglot persistence.
