{#ot-use-case-reference__table_jyf_xnv_xbc__entry__2}

| Term | Definition |
|-|-|
| Equipment model | The service records that describe how an industrial operation is organized to produce an output or product. |
| Production process | The relationships between equipment model entities and the various stages of the workflow from the raw material to finished goods. |
| Site | A parent equipment model entity record that has no parent. This is a special equipment model entity record because it is used to assign read or write level access to the OT devices assigned to the site. |
| OT device (site assignment) | The site assignment is needed for role-based security (RBAC) of OT devices. This is implemented as a choice list reference field on the OT Device Details (cmdb_ot_entity) table portion of the OT device record because an OT device can belong to only one site. |
| OT device (automates::automated) | The automates::automated by relationship describes how the OT device is related to the production process, which could include more than one equipment model entity. |
| Windows | In both OT and IT networks, the Windows server is represented in the cmdb_ci_win_server server. Additionally, the Windows server in the OT network has a reference in the cmdb_ci_win_server.cmdb_ot_entity field pointing to a record in the cmdb_ot_entity table that describes its function in OT and other OT characteristics like Purdue Level, site, and so on. |
