In the process of data standardization, the performance of relational database is encountering bottleneck. NoSQL, as its name suggests, is Not-only SQL, which can be a good complement to relational databases. In the report before the TechTarget database, ...

Research and application of large data query technology based on NoSQL database Zhu Jianseng Wang Jianxiong Zhang Junfeng based on NoSQL database theory, according to the different application scenarios, the NoSQL database is divided into high performance read-write, Document-oriented and distributed-computing-oriented 3 types. Comparing and analyzing the advantages and disadvantages of the 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 railway tickets, the paper chooses C ...

A data storage technology of map tile based on NoSQL Chen, Liang, Hao Wen, Juagen, Li Yuxiang, Shu Fangfibenwen Firstly, this paper introduces the origin and development of NoSQL (non relational database), compares the advantages and disadvantages of the relational database, and puts forward the storage strategy of map tile data based on NoSQL. The difference between the MONGO DB and SQL Serv-er 2000 in the storage and concurrent access performance of the NoSQL database products oriented to document is analyzed by experiment. The results show that the Mongo db in the mass space number ...

Introduction with the advent of the cloud computing era, various types of Internet applications are emerging, the relevant data model, distributed architecture, data storage and other database related technical indicators also put forward new requirements. Although the traditional relational database has occupied the unshakable position in the data storage, but because of its inherent limitation, has been unable to satisfy the cloud computing age to the data expansion, reads and writes the speed, the support capacity as well as the construction and the operation cost request. The era of cloud computing has put forward a new demand for database technology, which is mainly manifested in the following aspects. Mass data processing: to ...
