Domains

Available to: All users (view); Admins (create/edit/delete) Minimum plan: Free

A domain is an information subject area (e.g., Finance, Sales, HR) used to organise your tables and control who can access them. Every table belongs to exactly one domain. Permissions are granted at the domain level (or at the table level), so you can give your finance team access to finance tables without exposing HR data.

What Domains Do

Domains serve two purposes in TitanRDM:

1. Organisation

Every table definition belongs to exactly one domain. Domains let you group tables by business function, department, or any other logical boundary that makes sense for your organisation. Common examples:

Domain	Abbreviation	Example Tables
Finance	`fin`	Chart of Accounts, Cost Centres, Currency Codes
Sales	`sale`	Product Categories, Sales Regions, Customer Types
HR	`hr`	Job Titles, Department Codes, Leave Types
Operations	`ops`	Location Codes, Equipment Types, Status Codes

The sidebar navigation organises your tables by domain, making it easy to find what you need.

2. Access Control

When you create a domain, TitanRDM automatically creates two user groups with permissions scoped to that domain:

User Group	Permission	What It Grants
Domain [Name] Data Manager	`data manager`	Ability to view and edit data in tables within this domain
Domain [Name] Developer	`develop`	Ability to create, modify, and manage table definitions within this domain

By adding users to these groups, you control who can work with which subject areas. An account administrator can access all domains regardless of group membership.

Creating a Domain

Navigate to Admin > Domains in the sidebar
Click New Domain
Fill in the form:
- Name — a descriptive name (e.g., Finance). Must be unique within your account.
- Description — optional context about what this domain covers
- Abbreviation — a short code, maximum 4 characters (e.g., fin). Must start with a letter or underscore, and can only contain letters, digits, or underscores. The abbreviation is used the prefix (e.g. fin_...fin_gl_accounts) for physical database table names.
Click Create Domain

Create domain form

Note: The abbreviation is automatically lowercased. Once created, the abbreviation forms part of the database table naming convention, so choose it carefully (e.g. fin_...fin_gl_accounts).

Editing and Deleting Domains

Edit: Navigate to the domain's detail page and click Edit. You can change the name and description. The abbreviation cannot be changed after creation because it is embedded in physical table names.
Delete: From the domain's detail page, click Delete. This will remove the domain and its associated user groups and permissions.

Warning: Deleting a domain does not delete the table definitions within it, but those tables will become orphaned. Reassign tables to another domain before deleting.

Domain Permissions in Detail

Permissions in TitanRDM are additive — a user's effective access is the union of all permissions from all user groups they belong to. Domain permissions work alongside branch permissions:

To create or modify table definitions in a domain, a user needs both:
- develop permission on the domain (via the Domain Developer group)
- develop permission on the branch (via the Branch Developer group)
To edit data in a domain's tables, a user needs:
- data manager permission on the domain (via the Domain Data Manager group)
Account administrators bypass all domain permission checks

This two-dimensional permission model (domain x branch) gives you fine-grained control over who can do what, where.

Domains in the Sidebar

The Tables section of the sidebar displays your domains as expandable groups. Click a domain name to see its deployed tables. The tables shown depend on your current branch — each branch has its own set of deployed tables.
