How do you add objects to a new vector class in C++?

Question

My goal is to add objects from a class to a new class where they will be stored in a vector, which I will use later to add/delete/display elements. The vector will act as a database.

In the vector class, I am unsure if I am able to return the inputDB from object class. Any help will be appreciated. It doesn't necessarily have to be done the way I have wrote it.

Header file for Object

#ifndef OBJECT_H
#define OBJECT_H

#include <iostream>
#include <string>

Class Object
{
friend std::istream& inputDB(std::istream&, Object&)

private:
std::string Name

public:
Object(std::string name); //constructor

const std::string& getName() const {return this -> Name;};
}

std::istream &inputDB(std::istream&, Object&)

#endif // OBJECT_H

Source file for Object

#include "OBJECT.H"

Object::Object(std::string name){Name { name }} {};

std::istream &inputDB (std::string istream& is, Object& x)
{
std::cout << "Enter name: ";
is >> x.Object
return is;
}

New vector class header

#ifndef VECTOR_H
#define VECTOR_H

#include <Object.h>

#include <iostream>
#include <string>
#include <vector>



Class VectorDB
{
private:
std::vector<Object> DB;

public:
Database();
void inputDB(std::istream&)
}

#endif // VECTOR_H

Source file for Vector

#include "VECTOR.h"

VectorDB::VectorDB()
{}

void inputDB(std::istream& ist)
{}
