Rating and Weightage Storage

Summary

Owned storage for Rating, Weightage, CyclePeriod, and ReviewerRef value objects.

Backend engineers, database reviewers, architects, QA, support, operations, security reviewers, and product owners.

Value objects are mapped with EF owned types and share their owner's storage rather than receiving independent logical object sets.

Logical item	Classification or owner	Tenant/filter	Identity or mapping
CyclePeriod	ReviewCycle	Required owned mapping	Start/end period components
Rating	Appraisal	Required owned mapping	Overall evaluation component
Weightage	AppraisalGoal	Required owned mapping	Goal weight component
Rating	AppraisalGoal	Two required owned mappings	Self and manager evaluation components
ReviewerRef	AppraisalReview	Required owned mapping	Optional reviewer components
Rating	AppraisalReview	Required owned mapping	Stage evaluation component

Seven owned mappings represent four distinct value-object types.
Owned mappings create seven snapshot key and foreign-key declarations for table sharing; these are not independent logical object primary keys or aggregate relationships.
Value-object factories normalize bounded values and provide structural equality.
Owned values have no independent indexes; indexes belong to owner properties and query patterns.
No actual evaluation values are included here.

Implemented table-sharing value-object persistence.

Normalization policy, rounding governance, future migration compatibility, and independent indexing needs require confirmation.
