A primary driver of interest in NoSQL systems is their support for next-generation Web applications, for which relational DBMSs are not well suited. These are simple OLTP applications for which (i) data have a
This growing interest resulted in a number of NoSQL Database Management Systems (DBMS), with a focus on performance, reliability, and consistency. A number of existing indexing structures were reused and improved upon with the purpose of enhancing search and read performance. First, there were pr...
Data model.With NoSQL database systems, data isn't modeled as tables with fixed rows and columns, as with a SQL DBMS. Instead, depending on the NoSQL database, data can be modeled as JSON documents, graphs with nodes and edges, or key-value pairs. Wide-column stores use the table an...

Microsoft and other relational DBMS (RDBMS) vendors also eventually developed NoSQL databases. Now, in keeping with the overall market shift towardcloud databases, NoSQL systems are widely available in the cloud both for self-managed IaaS deployments and vendor-managed database as a service (DBaaS...
Most databases can only satisfy one or two fundamental DBMS requirements. Some are feature-rich with multi-model capabilities but aren’t fast or scalable. Some are fast and scalable but have limited features. Some are as easy as SQL, while others are programmatic. Some have a fixed schema,...
NoSQL Database Systems are an alternative to the mainstreamRelational DBMS. They don't use a relational data model and typically have no SQL interface. Although this type of systems exists for many years (some even longer than relational systems), the term NoSQL was first introduced in 2009 ...
