Based on the NoSQL database theory, according to the different application scenarios, the NoSQL database is divided into 3 types for high performance reading and writing, document oriented and distributed computing. Compare and analyze the advantages and disadvantages of 6 representative products of these 3 types of databases, Combined with the requirement of large data operation in the comprehensive analysis system of ticketing information for real-name railway tickets, the Cassandra Database for distributed computing in NoSQL database is selected. Based on the Cassandra database, the paper puts forward the technical framework of the comprehensive analysis system of railway ticketing real-name systems, And the reverse index is designed to construct the query strategy and query process of the real-name ticket information. Through performance test, it verifies the high availability of NoSQL database technology in processing large data query and analysis, which can break through the bottleneck of query performance, expansibility and investment cost encountered in the application of traditional relational database and data warehouse.
