What is the primary challenge when using the Table-Per-Concrete class (TPC) inheritance strategy in Entity Framework?
- Complexity in querying across multiple tables
- Difficulty in maintaining referential integrity
- Duplication of columns in the database
- Limited support for polymorphism
The primary challenge of using the Table-Per-Concrete class (TPC) inheritance strategy in Entity Framework is the duplication of columns in the database. Each concrete type in the inheritance hierarchy gets its own table, leading to duplicated columns for shared properties across multiple types. This duplication can result in redundancy and increased storage space.
