Answer: Customers create Custom objects to store data specific to their organization’s needs. These objects are similar to standard objects but custom-defined.

Answer: Custom Settings are comparable to custom objects, but they hold efficiently accessible static data that doesn’t use up SOQL limits. They are applicable to Apex code, validation rules, and formulas.
25. What is the difference between a Lookup and a Master-Detail relationship?
Answer: A Lookup relationship links two objects loosely, while a Master-Detail relationship links them tightly, with the child record inheriting the security and ownership of the parent record.
