With a ServiceNow instance, you can improve efficiency, add
greater security, and increase performance for your customer organizations. It's helpful to
understand some of the most common terms as you create your configurations.

## Managed domain {#bp-terms-conditions__section_oxc_bcn_rhb}

In a managed domain, the Managed domain field allows domain
administrators to manually select a domain for the user, group, department, location, or CI
record, rather than using the domain that is assigned automatically from the company record.

If you want to change those properties, you can override them to further customize the functions of the applications in each of your domains.

## Process tables {#bp-terms-conditions__section_nvr_hcn_rhb}

In process tables, if you see a value in the Overrides \[sys_overrides\] field, a process override record exists. That means that
delegated administration, which is how administrators can set domain-specific policies, is
in effect. Admins in the global domain can use the Expand/Collapse Domain Scope related link to see override records.  
Hinweis:  
Reports are separated into domains and contain an Overrides field. To view all reports from the global domain, use the Expand Domain Scope related link.

When you view process tables from a domain, you see only the relevant process records for
the selected domain. When you view a process table from the global domain, the
Expand Domain Scope related link is displayed to let you see all
process records, including overrides. To view only the relevant process records for global
again, use the Collapse Domain Scope related link.

The domain scope feature is used only for process tables and causes the visibility of data
on the table to shift in the opposite direction. For example, a record in the parent domain
can be seen in the child, but a parent cannot see a child record. This allows the process to
flow down to child domains.

## Types of domains {#bp-terms-conditions__section_igp_h2n_rhb}

Different types of domains can help you organize your processes and data and how they
function in the application or feature.

Customer Domain

In the customer's domain is the user interface, as well as the process that controls how
the data Is used.

The ACME domain in the following image is a customer domain.

Process Domain  
You create processes for how the data is used and what it does in the domain. These processes must have these attributes:

* Specific processes and UI settings for a set of domains
* No core data of any kind (such as specific user data).
* The TOP domain in the following image is a process domain.
{#bp-terms-conditions__ul_rxg_pfn_rhb}

Data Domain  
The data domain holds data that is relevant to multiple customers. That data can be shared without sharing the actual customer domains. Each customer has its own data domain and can access it.  
Hinweis:  
This kind of domain is not common and can cause performance issues if overused. Consult with an SP architect before use.

Example: The domain may hold tasks that ACME, Cisco, and the SP all need to interact with.

The Default domain in the following image is a data domain.

User Data

User record data never belongs in the global domain or any of the process domains. Users
are primarily created in customer domains and can on occasion be created in data
domains.

Admin accounts are special as they should not be used as everyday users of the instance and
should be in the global domain to facilitate administrative functions.

## Lists, admin, global process {#bp-terms-conditions__section_szq_fgn_rhb}

Lists

From the global domain, if you right-click any choice field's label, select
Configure Choices, and then add a new choice, the choice pushes
automatically to all domain-specific lists for that field. If the new option is marked as
Selected, it is added as active. If the new option is marked as
Available, it is added as inactive.

Instance Administration

The instance owner's administrators must handle all normal process creation, modification,
and maintenance in a domain-separated instance. Individual domain managers can maintain some
parts of data-driven processes. The types of domain managers maintain user administration,
support group memberships, and locations, or manage applications that are designed with
tenant administration in mind.

Global process/parameters

You can create and maintain the process that affect the global domain as well as set the
parameters. These properties are common for all users of a domain-separated instance.

Examples: System properties, dictionary overrides, `sys_documentation`
(field labels), the data model (classes, CI types, and so on), tables and fields
`[sys_dictionary]` (access can be restricted), indexing (text indexes as
well as database), ACLs, installation exits, inbound actions, public pages, and
interceptors.

* [Domain separation explained](https://servicenow-prod.fluidtopics.net/x9xyVWl9u0yhkSMd6PgbBw "With domain separation, you can segregate application data, UI, and business logic, such as rules or workflows, in a single customer instance. Separating these elements into logically defined domains supports specific hierarchies for all customers using your applications.")
* [Context and domain separation](https://servicenow-prod.fluidtopics.net/hSeeFgDzm2U__u_XsOCBsg "The context of a user's session determines the processes, data, and user interface (UI) as the user browses through list views, home pages, reports, and knowledge articles. The context is determined by the processes that you create, the business rules that you set, your workflows, and other factors.")
* [How a database query works with domain separation](https://servicenow-prod.fluidtopics.net/yQ9RQVyEkZdMQEmVYhCGCw "Using database queries with domain separation in your customers' applications help them protect their data. These queries then speed up the configuration and build processes.")
* [Domain-separate a custom table](https://servicenow-prod.fluidtopics.net/Lv2WmMnM3OxtInjuL8rlYw "You may need to create custom tables in separate domains. This topic covers both the procedure and the concept behind domain-separating a custom table.")
* [Customizing domain properties and themes](https://servicenow-prod.fluidtopics.net/o~73HsH~C~Y8lCJBbqNjKA "You can customize your customers' company properties and themes within the domains that you have configured. Customization makes their instances fit in with their companies' overall look and feel.")
* [Managing domain separation for specific uses](https://servicenow-prod.fluidtopics.net/~rh2XIdcd8JY~l2bgFgr~Q "You can set up separate domains for email notifications and customize the properties of catalog, tables, users, groups, and views. This enables you to provide more specific behavior in each domain, giving your customers more flexibility.")
* [Configuring domain separation with the domain picker](https://servicenow-prod.fluidtopics.net/dB~D65eJSYPmKEJYOgd2RQ "Use the domain picker wisely, and remember the 80/15/5 approach so that you do not customize too much and impact the performance of your instance.")
* [Domain separation performance considerations](https://servicenow-prod.fluidtopics.net/P8ZuAavQomgk_~ZYZYkfyw "As you configure domain separation in your application and services, make sure that you consider the number and properties of domains you create. Too many property-heavy domains can impact the performance of your instance.")
* [Setting up domain hierarchies](https://servicenow-prod.fluidtopics.net/~BeGlrS5mkBAZC8MgNeHNw "You can avoid slowdowns and performance impacts in your instance by knowing how domain hierarchies work and by setting them up properly.")
* [Checking domain logs for errors and warnings](https://servicenow-prod.fluidtopics.net/hTDpifH47t2Gr1s9ep3duA "Check the domain logs to find errors or warnings in your domain path processes and hierarchy configurations.")
* [Importance of the Default domain](https://servicenow-prod.fluidtopics.net/s60j9ApH7YvVauD3Os2I4w "Organizing your domains is a crucial part of the domain separation process. If you don't set a default domain, new tasks and user records go to the global domain. Anyone can see the records in the global domain, which means that data can be seen when it is not supposed to.")
* [Contains queries and domain access](https://servicenow-prod.fluidtopics.net/z9rKyulEpro~zy87l2cNMg "Use a \"contains\" query only in special cases, such as when users or groups need to see data from a domain that they don't have access to, but you don't want to move those users to a domain. Creating domain \"contains\" and user or group access for a domain should be an exception, only when absolutely needed.")
* [Domain paths query method](https://servicenow-prod.fluidtopics.net/yWArrf6dWdJiSqzk7MV0rg "You can create effective queries with domain paths.")
* [Slow queries and SQL debugging](https://servicenow-prod.fluidtopics.net/MDCvsO1Iv3cuVtEHAH_bfg "Debugging SQL and slow queries can help you resolve slowness issues in an instance.")
* [Before Query business rules](https://servicenow-prod.fluidtopics.net/dYg_2l53Fdrn0m68dyF7wQ "You can use a Before Query business rule to help support data segregation on an instance. ServiceNow applications that support domain separation may support the separation of data and data routing only, have advanced business logic separation, or support tenant (customer) level administration of the application.")
* [Avoiding domain path in scripts](https://servicenow-prod.fluidtopics.net/bv~55hFZ7r56GVb0sh0iDg "Domain paths can cause the values of your script to change or even break, so don't use them in scripts.")
