Research and Application of Large Data Query Technology Based on NoSQL Database

NoSQL database breaks the traditional relational model, stores data in a free way, provides a new access interface, and overcomes the shortcomings of traditional RDBMS. NoSQL database can be deployed on cheap hardware, supporting distributed storage, and transparently extending nodes. This paper analyzes the characteristics and applications of various types of NoSQL databases, and focuses on the application of the representative MongoDB in the large data query in the NoSQL database. The paper presents research and application of large data query technology based on NoSQL database.
