At first glance, it may seem that relationships and joins are quite similar, if not identical. However, there are differences in their substance and behaviors worth understanding to decide which option to use.
The obvious advantage of relationships is that they do not require any prior understanding of SQL-like join behavior, which makes them a great option for beginner users. Advanced users, however, may prefer the additional degree of flexibility that comes from defining which type of join to employ and which fields to use.
It is also worth mentioning that relationships may not work as intended for data where the quality is exceptionally poor and may cause performance issues if large quantities of data are needed.
