Save generic object in database

Question

My model is like:

public class MyModel{
    private String mId;
    private String mName;
    T mAnObject;
}

How can I store T object in database.

@AndreiT If it can be object then will be more feasible for me — Charu, Aug 16 '16 at 11:39
That doesn't make sense. You can't store an object in a database. You need to serialize and deserialize it. — Ricky, Aug 16 '16 at 14:11

If you need to save specific properties, just do that, otherwise you could serialize it to JSON, as an option (as demonstrated here).

Example: Object myObj has three properties: String title, String subtitle, String text

1 - You can save them as separate database rows and then when you read from the database you recombine them to create your Object.

2 - You can also use Json to save the properties, this way you only need to store a single String in the database and when you read from the database convert the Json String to your Object.
