title: Realm Database Multiple Tables
body: <p>I got confused about the concept of tables and realm although I read the Realm documentation.
  As I know a realm is a like Table, but it can store multiple Models.
  The problem is, I want to have multiple tables (some of them just contain objects of 1 class, and some multiple classes) but I don't know how to manage multiple realms.
  I want my "Database" class to be a wrapper for RealmDatabase and I want multiple Tables in it, for example, a table for "new songs" and a table for "best songs". So what I did was:</p>
  
  <pre><code>public class Database {
  //tables that I want to have
     public enum RealmType {
      SONGS_NEW, SONGS_BEST, PLAYLISTS_BEST, PLAYLISTS_MINE, PLAYLISTS_OTHERS, ALBUMS_SPECIAL, NEWS, FEED
     }
  
     private static final String TAG = "Database";
  
     Context context;
     //A realm object for each table
     Realm profileRealm;
     Realm songs_newRealm;
     Realm songs_bestRealm;
     //and so on...
  
  // as I didn't know how to differentiate between Realms (all of them are created with Realm.getDefaultInstance(), and I think they are just one Realm. so I created a class for different configs )
  private static class RealmConfigs {
          static RealmConfiguration songs_newConfig;
          static RealmConfiguration songs_bestConfig;
          //and so on..
          public RealmConfigs() {
              config();
          }
  
          private static void config() {
              songs_newConfig = new RealmConfiguration.Builder()
                      .name("songs_new.realm")
                      .deleteRealmIfMigrationNeeded()
                      .build();
              songs_bestConfig = new RealmConfiguration.Builder()
                      .name("songs_best.realm")
                      .deleteRealmIfMigrationNeeded()
                      .build();
          }
      }
  }
  </code></pre>
  
  <p>But it just doesn't feel right. I know that I'm confused in Realm's core concepts but the documentation just didn't help either. A clear explanation on how to correctly manage different Tables and initialize them would be appreciated.</p>
  
  <p>PS. I found this answer as well but it doesn't feel right either:
