Database as a Service is a database model where by a client or user accesses database resources over the internet. It is a form of cloud computing where computing resources – in this case a database – is owned, controlled and managed over the internet. One type of Database as a service model is the NoSQL data model. NoSQL refers to a variety of various database tech developed as a response to the demands of building modern-day applications. There are various types of NoSQL databases, and some of them include document databases, which pair a key with a data structure called document, graph sores that store information on networks of data like social connections, wide-column stores, as well as key-value stores. NoSQL databases have the advantage of being more scalable than relational databases, and they provide a higher performance too. NoSQL database model also addresses issues that relational models cannot address. Some of the other benefits of NoSQL model are a quick iteration, frequent code pushes, and agile sprints. They also handle large data volumes, whether unstructured, semi-structured, or structured. The advent of cloud computing, open source software, and commodity servers have made organizations adopt scale-out architectures, all of which NoSQL can handle.
