easy to query.

int id = 100;
string name = "hunt";
auto repository = new UserRepository;
auto user = repository.findById( id );

import hunt.entity.domain.Condition;
auto user1 = repository.find(new Condition("%s = %s AND %s = %s", repository.Field.id, id, repository.Field.name, name));

easy to delete.

int id = 100;
auto repository = new UserRepository;
repository.removeById( id );

easy to insert.

auto repository = new UserRepository;
User user = new User;
user.name = "Hunt";
user.email = "[email protected]";
auto user = repository.save( user );
repository.insert( user );

easy to update.

int id = 100;
auto repository = new UserRepository;
auto user = repository.findById( id );
user.name = "Hunt-framework";
repository.save( user );
repository.update( user );
