Database Client Design to support different backends

I need to implement some kind of simple database client, which can perform CRUD operations on a database. However, it should be designed in such a way that it is easily possible to replace the backend (e.g. mongoDB) with another one (e.g. postgres) or whatever.

What design patterns would you suggest to implement?

As a very simple approach, I would simply create an interface which defines methods for all the CRUD operations:

interface DBDriver {
  void write(String data);
  String read();
  ...
}

Classes implementing this interface would then be injected in a Client class like:

class DBClient() {
  public DBClient(DBDriver dbDriver) {
    ...
  }

  //methods like write, read, update ...

}
