数据库客户端设计支持不同的后端

What are usable design patterns to use for implementing a data base client capable of supporting various backends? (e.g. mongodb, or postgres,...)

用于实现能够支持各种后端的数据库客户机的可用设计模式有哪些?(如mongodb或postgres…)

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

作为一种非常简单的方法，我只需创建一个接口，为所有CRUD操作定义方法:

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

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

实现此接口的类将被注入到客户端类中，如:

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

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

}
