Create FK field ClientId or create relationship field

does relationship property working the same as adding FK in another collection

TL;DR

The user is asking about creating a relationship field or a foreign key field. They mention that the configuration is different depending on whether the information is shown in both collections or only one. There is confusion about the two-way nature of the relationship. The user is referred to the documentation for more information. Solution: The user is provided with an example code snippet for creating a relationship attribute with a two-way relationship. The onDelete property is set to "cascade". Finally, the user asks if the relationship property works the same as adding a foreign key in another collection.

await databases.CreateRelationshipAttribute( databaseId: "marvel", collectionId: "movies", relatedCollectionId: "reviews", type: "oneToMany", twoWay: true, key: "reviews", twoWayKey: "movie", onDelete: "cascade");

what is twoWay mean?
