When dealing with a legacy database that has a non-standard table structure, how can you implement inheritance in Entity Framework to accommodate this?
- Use Joined Tables (JT) strategy, mapping each class in the hierarchy to its own database table with a one-to-one relationship between the base class table and derived class tables.
- Use Table per Concrete Type (TPstrategy, mapping each class to its own database table, including inherited properties.
- Use Table per Hierarchy (TPH) strategy to map all properties from all classes to a single database table.
- Use Table per Type (TPT) strategy, mapping each class in the hierarchy to its own database table.
Using the Table per Hierarchy (TPH) strategy would be the most appropriate approach. TPH allows mapping all properties from all classes to a single database table, making it suitable for accommodating non-standard table structures in legacy databases. This simplifies the mapping process and aligns well with the existing database schema, reducing the need for extensive schema modifications. However, it's essential to consider potential performance implications, such as NULL values and table size, when implementing this strategy.
