Implement Realm Design for Tags

Question

I know Realm is NoSQL and doesn't support join operations. Currently, I have MySQL database having tables like this -

Table: Data
Columns: DataID, Title

Table: Tag
Columns: TagID, Title

Table: DataTag
Columns: DataID, TagID

How can I implement a Realm Model for this type table structure?

Answer 1

public class Data extends RealmObject {
    @PrimaryKey
    String dataId;

    String title;

    RealmList<Tag> tags;

    //get,set
}

public class Tag extends RealmObject {
    @PrimaryKey
    String tagId;

    String title;

    RealmList<Data> datas;

    // get, set
}

Setting up relations is manual.
