What is the alternative for replacing a table with a referencing entity, and why is it not possible to drop the table when it is being referred to by an object?

The alternative for replacing a table with a referencing entity is to use foreign keys. Foreign keys create a relationship between two tables where one table references the primary key of another table.

It is not possible to drop the table when it is being referred to by an object because the object relies on the table for its data. Dropping the table would cause the object to lose its reference and would result in errors or data loss. It is important to consider the dependencies and relationships between tables before making any changes to the database schema.
