PuiduDetailId

Puidudetailid is a term used in some software systems to refer to a unique identifier for a detailed sub-record that belongs to a parent entity often labeled as puidu. It is not a universal or standardized term, but rather a descriptive label that appears in database schemas, APIs, and data models where a parent detail relationship is modeled.

In data modeling, puidu detail id typically serves either as part of a composite key with the parent puidu identifier or as a separate primary key for the detail row. It enables one-to-many relationships, where a single puidu may have multiple associated detail records. Proper indexing on puidu detail id and its parent key improves query performance and helps maintain referential integrity, especially under operations such as insert, update, or delete cascades.

Common data types for puidu detail id include integers or UUIDs, depending on the system’s requirements for uniqueness, distribution, and portability. Some implementations use a numeric auto-increment or a globally unique identifier, while others store the value as a string in serialized formats. Consistency in naming—such as puidu_detail_id in snake_case or PuiduDetailId in PascalCase—facilitates readability and integration across services.

Typical usage patterns include API routes and database queries that reference both the parent id and the detail id, for example retrieving a specific detail by GET /puidus/{puidu_id}/details/{puidu_detail_id} or querying detail records by puidu_id in SQL. The term emphasizes linkage and granular identification within hierarchical data structures.
