In a scenario where a query involves multiple nested relationships, how do you ensure efficient data retrieval?

When dealing with multiple nested relationships in a query, utilizing eager loading can be an effective strategy. Eager loading retrieves all related objects and their nested relationships in a single query, reducing the number of database trips and improving performance. This approach contrasts with lazy loading, which defers the loading of related objects until they are accessed, potentially leading to additional queries and performance overhead. Caching can also enhance performance by storing frequently accessed data in memory, further reducing database round-trips. Optimization of the query execution plan is a broader concept that involves various techniques to improve query performance but may not specifically address nested relationships.
