Can you highlight the advantages and disadvantages of the lazy data loading strategy?

Eager loading strategy means that related data is loaded immediately along with the main object, rather than on demand.

Advantages:

• Reduces the number of database queries, as all necessary data is retrieved at once.
• Improves performance when accessing related data later, as it is already loaded.

Disadvantages:

• May lead to loading a large volume of unnecessary data if related objects are not used.
• Increases response time during initial load due to the large volume of data.

Thus, eager loading is effective when it is known that related data will be needed immediately, but it is not suitable if there are many related data and they are rarely used.
