Elementary and secondary schools, which had been delayed under the aftermath of Covid-19, have begun to establish online education in parallel with the start of the semester, considering the concerns about further infections spread. During the pandemic period, there is an open-source database company that has stably supported the online opening of the Korea Educational Research and Information Service (KERIS) since early March of 2020. Together with Naver Business Platform (NBP), Bespin Global, and Fusionsoft, CUBRID has provided technical supports to the online learning services operated by KERIS.


The number of users of digital textbooks and learning communities (Wedorang) had increased since the beginning of March when the beginning date of schools in South Korea was postponed during this pandemic period. To accommodate this expansion stably, the four companies mentioned above have provided services such as tuning supports for the existing virtual machine (VM) environment. In addition, after the announcement from the Ministry of Education regarding the online school opening at the end of March, in order to expand the number of service users, the system was transferred from the existing VM environment to the BM (Bare Metal Server) environment; the DBMS was rebuilt so that students can access the system by distributing the learning community (Wedorang) system, which was in operation when the second online school opened.


CUBRID has supported the online schools’ operation by ensuring stable service through database (DB) server optimization during the system operation and expansion period for about three months. The advantage of open source DBMS is that it can be supported smoothly by a technical support service contract without any restrictions on license purchase when expanding to large-scale servers.
