NoSql
NoSQL systems are non-relational database tools. The approach is to not use the relational model typical of traditional RDBMS systems to represent information. Think of scenarios where the data to be handled are impressive; typical examples are the cloud computing systems of large web operators: in these contexts an approach that tends to scale horizontally is preferred to traditional DBMSs that under these conditions of use have different limitations.
Therefore, a NoSQL database is more versatile when traditional relational DBMSs tend to become larger and when they need to climb vertically, and so they require an increasingly high performance and costly hardware.
