detailset

Detailset is a term used in data modeling to denote a logical grouping of attributes that describe the detailed properties of an entity. It is typically used to separate core or identifying attributes from descriptive or optional details. The concept emphasizes modularity, allowing systems to extend or customize a data model without altering the primary entity schema.

In relational designs, a detailset is often implemented as a subsidiary structure linked to the main record, such as a separate table or a join-based collection. Each entry represents a detail associated with the parent and can be added, removed, or queried independently. This supports optional or variable attributes and can improve data organization and scalability, at the cost of additional joins in queries.

In document-oriented or object-oriented models, a detailset may appear as a nested document or component that travels with the main entity. This approach can improve read locality and reduce join overhead when details are frequently accessed together with the parent.

In user interfaces, a detailset commonly appears as a details panel or section that lists the detailed fields or specifications for an entity, enabling users to view or edit extended properties without cluttering the primary view.

Examples include a product that has a detailset of technical specifications, a vehicle record with maintenance details, or a user profile with privacy preferences. The term is often used descriptively rather than as a formal standard, and implementations vary across systems.
