cmdb_read is the minimum role required to subscribe or unsubscribe a CI.

cmdb_read is contained by other roles listed in the options and is the minimum required role.

Please note that reading CMDB tables requires the cmdb_read role; however, accessing the Configuration module requires the asset, itil, or itil_admin role.

Multiple versions of a workflow can exist at the same time. However, only one published version of a workflow ever exists.

When a workflow is invoked, the current workflow definition is loaded into the workflow context.

The checked-out workflow executes for the developer who has the workflow checked out.

Workflows are typically not published until development is complete.

Flow Designer can be used to:

orchestrate business processes across services with little technical user knowledge,

reduce technical debt, such as reducing scripting to simplify upgrades and deployments, and

integrate with 3rd party systems.

It is not suitable for existing logic already developed using the ServiceNow workflow editor and for the ServiceNow Instance running Jakarta or prior.

The ServiceNow Delegated development and deployment application enables non-administrators to develop and deploy applications.

Delegated development allows designated users without a system admin role to develop or deploy applications on the Now Platform.

If you have the application-specific admin role or the system-level admin role, you can delegate application development to designated developers at the application level.

User Criteria control who can read and contribute and are available at Knowledge Base, Knowledge Article, and Knowledge Block levels.

User criteria enable you to allow access to users based on role, department, group, location, or company.

You can assign user criteria to control read or contribute access. For example, you could enable all users in your Support department to have contribute access to a knowledge base by creating a user criteria record with the required department set to Support and then including the user criteria record in the Can Contribute user criteria.

Note: To create a user criteria record from the Knowledge module, you must have the user_criteria_admin role in addition to the knowledge role.

Can write is NOT a database setting on the Application Access section of a Table.

All the other options are the database settings on the Application Access section of a Table.

Application access settings determine whether one application can access resources from another application. They are similar to access controls (ACLs) in that they allow you to restrict access to certain resources. Still, instead of restricting tables and records from users, they restrict application resources from other applications.

Many-to-many relationships allow a list to point to a list of entries rather than to a single field.

For a list to be related to another list, a many-to-many relationship that refers to both tables must exist.

The Many to Many Definitions [sys_m2m] table allows administrators to create custom many-to-many relationships.

You can use the CSDM as a blueprint to map your IT services to the ServiceNow platform. The CSDM is a CMDB -based framework that identifies where to place data for the products that you're using. Also, the CSDM is the standard for all ServiceNow products that use the CMDB. Following the CSDM framework ensures that your ServiceNow application's data maps correctly to the appropriate CMDB tables.

If you don't follow this standard, you may not receive the full benefit of the ServiceNow products on the Now Platform.

The CSDM is standard terms and definitions, best practice for CMDB data modelling and data management, base system CMDB core tables, guidance on service modelling and recommended mappings.

The CSDM is not a process or implementation guide for ITSM, SPM, APM, EM, or other products, a set of reports, code to install, an SKU or product we sell or an automatic fix for past implementations.

A table is a collection of records in the database. Each record corresponds to a row in a table, and each field on a record corresponds to a column on that table.

Therefore, each column in the list interface corresponds to a field on the table; however, the list does not necessarily display all fields from the table.

Applications use tables and records to manage data and processes, such as Incident, Problem, and CMDB. Tables can extend other tables, creating parent tables and child tables.
