![]() ![]() Third, we compare for each NoSQL data model the main available technical solutions. Second, the four major types of NoSQL databases are defined and compared: key-value stores, document databases, column-oriented databases and graph databases. Such as: scalability, performance, consistency, security, analyticalĬapabilities and fault-tolerance mechanisms. NoSQLs evolution and mechanisms as well as the advantages andĭisadvantages of the main NoSQL data models and frameworks.įor this purpose, first, a deep comparison between SQL and The goal of this article is to establish a precise picture about But, this is at theĬost of a rigid storage schema and a complex management.Ĭertainly, data integrity and consistency are required in manyĬases like in financial applications but they are not always needed. ![]() In fact, the traditional RDMS ensuresĭata integrity and transaction consistency. Sets, the need of cheaper storage or the need of less management To many issues encountered when dealing with some specificĪpplications like those of Big Data (e.g., storage of very large data NoSQL solutions have been created to respond
