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.
