怎样创建数据库和连接啊???

我要做一个学生信息管理系统,并用VC++进行连接,请问要先做什么??
是先用VC进行连接吗??还是先做好数据库啊??

我什么都不懂啊,请各位大虾指教一下做这个学生信息管理系统的具体流程吗??
越详细越好

arrayqueue()
{
rear=0;
length=0;

}
void enqueue(int el);
int dequeue(int el);
int getfront();
//void makeempty();
int input();
bool isempty()
{
return length==0;
}
bool isfull()
{
return length==max;
}
//private:
int rear ,length;
int *element;
int el;
int max;
int size;

};
//

arrayqueue::arrayqueue( int )//:rear(max-1),length(0),max(size)
{
element =new int[max];
//if(element!=0)

}

void arrayqueue::enqueue(int el)
{
if(!isfull())
{
length++;
rear=(rear+1)%max;
element[rear]=el;
}
else cout<<"sorry ,the queue is full"<<endl;
}

int arrayqueue::dequeue(int el)
{
if(!isempty())
length--;
return element[(rear-length+1+max)%max];
}

int arrayqueue::getfront()
{
if(!isempty())
return element[(rear-length+1+max)%max];

}

int arrayqueue::input()
{
cout<<"input the number of array"<<endl;
for(int i;i<=max;i++)
cin>>element[i];
for(int i;i<=max;i++)
cout<<i<<element[i]<<endl;
}

int mian()
{


//rear=re;length=le;

//t arrayqueue r (re,le,m);

arrayqueue r(10);
r.input();
r.isempty();
r.isfull();
//cout<<"put int the number you want to insert"<<endl;
//cin>>el;
r.enqueue(7);
//cout<<"put int the number you want to delete"<<endl;
//cin>>el;
r.dequeue(7);

r.getfront();
//r.makeempty();
//~arrayqueue();
return 0;

}
