## 3.5 About APEX Database Accounts

Oracle APEX creates the following database accounts at installation.

- `APEX_260100` - This schema-only account owns the APEX platform schema and metadata. This account is always locked.
- `FLOWS_FILES` - This schema-only account owns the APEX-uploaded files that are not stored in workspace schemas. This account is always locked.
- `APEX_PUBLIC_USER` - This minimally privileged account is used for APEX configuration with Oracle REST Data Services.
- `APEX_PUBLIC_ROUTER` - This minimally privileged account is used for an ORDS REST module to resolve friendly URLs.

If you configured RESTful Web services, APEX also creates the following additional accounts:

- `APEX_REST_PUBLIC_USER` - This account is used when invoking RESTful Services definitions stored in APEX.
- `APEX_LISTENER` - This account is used to query RESTful Services definitions stored in APEX.

If you are upgrading from a previous release, all of the above accounts may already exist except `APEX_260100`.
