Utilizando a tecnologia de banco de dados NoSQL: um caso prático

Abstract

This paper addresses the NoSQL technology with regard to the four models available, Column Family, Documents, Graphs and Key-Value. Four tools were defined that implement respectively Cassandra, MongoDB, Neo4j and BerkeleyDB. Tests were carried out considering the main commands of the SQL language for defining and manipulating data in PostgreSQL DBMS, aiming to differentiate their commands those proposed by NoSQL technology, such as the description of the procedure performed to create a base in a relational environment compared with the conventional run for creating a base in NoSQL technology, differentiating the operation for each tested tool. The results identify similar commands and other totally distinct from commands executed in a relational database.
