Users/Roles
Creating a User/Role
A database is used by many users, and the users are grouped for management convenience. A database role represents a database user or a group of database users.
Users and roles have similar concepts in databases. In practice, you are advised to use a role to manage permissions rather than to access databases.
- Users: They are set of database users. These users are different from operating system users. These users can assign permissions to other users to access database objects.
- Role: This can be considered as a user or group based on the usage. Roles are at cluster level, and hence applicable to all databases in the cluster. A role is a cluster-level definition and applies to all databases in a cluster.
