And a basic question about it rose in me spontaneously. Early in the seventies Ted Codd published relational model as an improvement over the hierarchical model that had been used for data storage until then. So why do we still need a hierarchical model for data storage? Features mentioned like full text search, versioning, transactions, observation, and more can be just as well implemented with the relational model. And what does unstructured data mean? It sounds to me like random noise. - rami
