Dynamic Querying In NoSQL System

Reshma Suku, Kasim K.

Three mege trends Big data, Big user and cloud computing that leads to the adoption of NoSQL. NoSQL simply means Not Only SQL. Today most of the applications are hosted in cloud and that available through internet. They must support large number of users 24 hours a day, 365 days a year. This create explosion in number of concurrent users. So here needs a technique to handle large number of data. This paper proposes a dynamic query form interface for database exploration of an organization. Here use a document oriented NoSQL database ie, MONGODB. MONGODB support dynamic queries that do not require predefined map reduce function. The generation of a query form is an iterative process guided by user. At each iteration, system automatically generate ranking list of form components and user adds the desired form component into query form and submit queries to view query result. There are two traditional measures to evaluate the quality of query result ie, precision and recall. From the quality measures we can derive overall performance measure as Fmeasure.
