Data architecture - Concept
Data domain
A defined area of related data, such as customer or finance information, with clear ownership
What's it for?
Splits an organisation's data into clear subject areas so responsibility is easier to assign.
For example…
Customer data and billing data are managed as separate business areas
Customer data is treated as one data domain with named owners, definitions and quality rules, while finance data is governed separately.
Think of it like…
Departments in a company—each covers its patch but still connects at the boundaries
