OceanBase Developer Center (ODC) allows you to create private and public connections. A private connection is created in ODC by a user who obtains the database access information that is not shared with all users for the sake of security. The administrator can create public connections in ODC, combine multiple public connections to create resource groups, and grant the access permission of public connections or resource groups to specific roles.
Log on to ODC as the administrator and go to the Public Resource Console page. In the left-side navigation pane, choose Resource Management > Public Connections to display the Public Connections page.
