Application of NoSQL database MongoDB

Abstract

NoSQL database is the broad definition of nonrelational data storage. As a result of the new storage model, the traditional normal-form theory difficult to adapt to new applications. In this paper, the characteristics of the data logic model of NoSQL database MongoDB and the mode design principles were analyzed, then a method based on anti-normal form model was proposed. This method is based on the theory of data dependency and uses the strategy of decomposition or joint data for the different dependencies to achieve the logic schema design of non-relational database.
