I want to use a centralized database and am looking at various options to do so. From my understanding, I have three main options: SQLite, Realm, and CoreData. Are these options fine for a large centralized database for all users.

Additionally, I am trying to import data from JSON and CSV into a Realm database. Does Realm have this functionality?

As for now Realm does not seem to have the import functionality that you need. Check this thread for more information.

Realm does have a great documentation that you can read at Realm and for SQLite there is this framework (there are for sure more out there) and they both support Swift 2.x. You have to check what suits your requests most.

I can also recommend you to read this database thread at reddit.

View Your Data, When importing files into Realm, the process is a little more complicated. This is because Realm needs to generate a schema for each type of  Realm (-java) comes with an useful method: realm.writeCopyTo(File file). It can simply export your database in a .realm file somewhere. It can simply export your database in a .realm file

public String composeJsonFromRealm(){
        ArrayList<HashMap<String, String>> wordList;
        wordList = new ArrayList<HashMap<String, String>>();
       // Build the query looking at all users:
        // Execute the query:
        RealmResults<User> users = realm.where(User.class).findAll();

        if (users.size()>0){
                User user = users.first();
                HashMap<String, String> map = new HashMap<String, String>();
                map.put("name", user.getName());
                map.put("email",user.getEmail());
                wordList.add(map);


        }

        Gson gson = new GsonBuilder().create();

        return gson.toJson(wordList);

    }

Introducing Realm Cocoa Converter, realm file somewhere. RealmBackupRestore.class. So, we start making two methods to backup and import data. public void backup() { try { Specify the Server and Database from where you want to import data using native database query. Expand the SQL Statement field and paste or enter your native database query, then click OK .

I am trying to import data from JSON and CSV into a Realm database. Does Realm have this functionality?

With Realm Cocoa Converter you can import CSV, XLSX, and JSON, and export CSV data. Though, at the moment, it only supports OS X.

Example class to Export/Import a Realm database on Android (1/3), The conventional approach would be to first save the data files (excel or Here we can also import CSV/Excel file to generate the realm file. A Realm database is just a file you can backup any way you want. You can use RealmConfiguration.getPath() to get the actual location of the file. cmelchior added T-Help S:Waiting For User labels May 23, 2016

As of now, Realm Studio does have the import functionality from CSV.

Open the Realm Studio, File -> Create Realm from -> CSV
