What does Single Data Model Single System Of Record means in CMDB?

[Aakash Bhagat]

Single System of Records / Consolidate on a single platform

Break down silos and leverage a single system of action easily effectively and across all applications and processes on the Now Platform. Know what assets are in the environment (environment can be spread across multiple iaas or on-premise)and the dependencies across those assets.

Single data model

Each ServiceNow instance has its own database and is used to store data in tables comprised of various columns. While each application has its specific set of tables and columns, there are some tables like users, cmdb_ci, and tasks shared by many different applications. All records stored in tables are structured quite similarly with the column sys_id as the unique primary key thus enabling a single system of records that correlates all business services and processes throughout the enterprise

Hi Ankita,

Details as per Service Now.

Single data model ServiceNow CMDB utilizes a single, shared data model with common processes, standard taxonomy, and pre-negotiated semantics, format, and quality standards for exchanged data. As a result every table, view, and application built on the Now Platform leverages a consolidated, single system of record. This data model is also easily extensible: out-of-the-box tables and views can be extended with a click; fields from other tables can be referenced and used to drive workflow; and data validation and normalization rules ensure that trusted data can be leveraged across any application, form, or workflow.
