Inheritance Mapping Selectorv1.0.0

An online retailer needs to model products with shared attributes (SKU, price) and variant-specific attributes (size, color for clothing; storage, RAM for electronics). Using STI leads to many null columns; CTI causes complex joins for polymorphic queries. This skill recommends joined inheritance (class table) or mixed strategy.

A healthcare platform must persist different claim types (medical, dental, pharmacy) with distinct fields but common attributes (patient ID, date, amount). Regulatory requirements demand strong foreign key enforcement across tables. The skill selects class table inheritance to maintain referential integrity and manage divergent fields.

A CMS manages articles, videos, podcasts, and galleries with shared metadata (title, author, publish date) but very different content storage. Concrete table inheritance (table per class) best isolates each type's schema, avoiding wasted space and enabling independent schema evolution.

A trading platform supports multiple account types (Individual, Joint, Corporate) with unique rules (tax IDs, authorized signatories) but frequent polymorphic queries to retrieve all accounts for a user. The skill identifies STI as optimal due to few differentiated fields and high query performance needs.

A SaaS platform allows tenants to define custom entity types (e.g., CRM objects like Lead, Contact, Deal) that share a base structure but have tenant-specific fields. The skill suggests a hybrid approach: STI for core fields with a separate JSON column for extensions to balance query simplicity and flexibility.

Offer database design consulting engagements where the skill accelerates inheritance mapping decisions for clients, reducing design time and risk. Revenue from hourly or fixed-fee consulting.

Integrate the skill into an IDE plugin or code generation tool that automatically suggests and generates Hibernate/JPA/Django ORM configurations. Revenue via subscription or per-seat license.

Package the skill as part of a training module for software architects on ORM design patterns. Sell access to video lessons, exercises, and the skill as a decision support tool.
