For example (first class): @Entity public static class Store { @ OneToMany (targetEntity = Offer.class, mappedBy = "store") private List offers; } second class: @Entity public static class Product { @ OneToMany (targetEntity

Hello everyone, I have a question regarding the OneToMany / ManyToOne Relationship in ObjectDB. So imaging following setup: We have class A which holds an collection (List, Arrray ...) of class B. In a more usual DB like MySQL with a seperate server we first query for the Entitys of class

Do the following annotations @ OneToMany @ManyToOne @ManyToMany @OneToOne imply @Index   ? Thanks, Carl   FastModel Ben Schreiber Actually these annotations (except @ManyToMany ) should apply @Unique on the @One side. But ObjectDB doesn't apply these indexes automatically
