Avaliação de desempenho entre bancos de dados relacionais e NoSQL

Abstract

With the large volume of data generated by Web 2.0 applications and the constant need to keep the most of the available services and to have a flexible structure, is the use of eminent NoSQL (Not Only SQL) for these applications. But much yet, questions remain about the advantages and disadvantages of NoSQL solutions. This paper presents a comparative performance study between relational databases and NoSQL database, in a scenario that uses Junction when used with relational model. Tests are performed in the INSERT, UPDATE, DELETE, and SELECT operations and quantitatively measured the execution time for each operation. Each test was described and represented in the form of graphs, as well as critically examined and discussed.
