摘要：Relational databases have been widely used in organizations for decades. Although relational databases have significant advantages for data preservation and concurrency controlling as the standard model in databases, there are disadvantages as well, such as object relationship inconsistency and heavy dependence on strict database schema. Recently, NoSQL became the alternative for big data utilization in that it can be operated without a specific schema while works well in cluster environment in the 21st century. However, its utilization still has pros and cons. In this backdrop, we do not only enumerate the advantages and disadvantages of NoSQL on relational databases, but also show the comparison between the NoSQL databases. More importantly, this research does not necessarily recommend the specific single type database to build an information system. Instead, using the polyglot persistence concept, we suggest the database management system selection criteria. Then we present an optimal combination of the database system in order to demonstrate our suggestion from the example of the smart education service in Korea
