Delayed loading:

It is only loaded when the data is needed, and does not load when the data is not needed. Delayed loading is also called lazy loading.

Advantages: first query from a single table, and then associate the query from the associated table when needed, which greatly improves the database performance, because querying a single table is faster than querying multiple tables.

Disadvantages: because database queries are carried out only when data is needed, in large quantities of data queries, because the query work is also time-consuming, it may result in longer user waiting time and a decline in user experience.
