Analysis of various NoSql database

In the age of internet, when data production has gone off-bounds, organizations are facing a tough challenge in terms of processing, analyzing and storing big data. The major drawback with this data is that it is not only being created at a lightning fast pace but it is also unstructured i.e. does not have a fixed schema. Moreover it is arising from disparate and discrete sources such as the social media. NoSql or Not Only Sql databases offer a highly flexible and horizontally scalable solution to store structured, semi-structured and unstructured data. These databases store data in the form of key-value pairs which offers better availability and high throughput performance in terms of processing queries. They are designed to be highly customizable according to the user's requirements, and well suited for the needs of the overlying application as well as the underlying data being stored. This paper firstly provides a general overview of the NoSql storage technology. Later a thorough analysis will highlight the features, strengths and limitations of six most popular NoSql databases and thus would help the organizations to choose a NoSql database which is well-suited to their needs.
