While dealing with subtype associations, it is essential to have a conversation about the many different possibilities for database tables that are accessible.Choose the format that you want to utilize, and then debate the issues that are relevant to the layout that you chose.
Describe the concept of database denormalization and when it might be appropriate to use in database schema design. What are the trade-offs associated with denormalization?
When using subtype associations, it's vital to talk about the different database table alternatives. Choose a design and talk about the issues that will develop as a result of it.
