In database design, what is the difference between single-table inheritance and class-table inheritance?
- Creating separate tables for each subclass
- Embedding all attributes in a single table
- Storing subclasses in different databases
- Using a combination of single and multiple tables
Single-table inheritance involves embedding all attributes of the superclass and subclasses into a single table. This approach simplifies queries but may lead to null values and decreased performance for large datasets.
