One to Many Relations | Backendless Database Training Course (pt. 35)
In this video, we discuss one-to-many relationships in databases, which is a type of relationship where one entity of one kind is related to a collection of other related entities of another kind. We provide examples such as country and cities, person and parents, and customer and orders. We demonstrate how to import a sample database to your application, which has a country and a city table with a one-to-many relationship. We show how to manage the relations, how to add and remove related objects, and how to navigate through the schema. Additionally, we discuss the design considerations when establishing one-to-many relationships, and why it is essential to consider them during the design phase. By the end of this video, you'll have a good understanding of how one-to-many relations work in databases and how to use them in your applications.
