How to incorporate Database into C++ ?

[RPA]

Does Anybody know how to use C++ to get information from a database? I have this assignment due but , I do no know to incorporate a database into my program. My program is to allow a user to choose from NFL football teams,when the user picks the team , they will see that teams 2004 draft picks.Here is how I have started without using a database.

function file:

#include <fstream>                //for file I/O                                               *
#include <string>
#include <iostream>              //for cin and cout                                            *
#include "2004draft.h"
#include <math.h>
#include <stdlib.h>                //for exit()                                                *


using namespace std;


const double pi = 3.14159;

IF anybody has some useful info I would appreciate it.

Hello,

A database is nothing more than a file with a certain pattern for data storage. In order to pull data from a database, you need to know HOW the data is internally stored within that file. A database could be a flat file, with one record per line, or it could be a binary file with internal search keys and other encoded data.

In order to help you with your code, you will need to tell us how the database is formatted, and you should also take a stab with the code to read it out and into variables. Chances are, you will need to put the data into a memory array or linked list, and you are going to need storage buckets to hold the data and the linked information together.

Good luck with it.

Guys and gals just dont seem to understand file handling
Check this link http://www.daniweb.com/techtalkforums/thread5720.html

I give a basic intro on how to use a database.It's just the steps you can follow to retrive or write data.I use structs but you can also uses classes(Hey calsses are just structures with funtions attached,so you can write them to a file).

Many seem to have a problem with file handling and databse.[Does anybody want a full blown tutorial on fstream file handling and databses in C++,i will do one if ya want]

Thanks firenet. Yeah i would like a tutorial on the subject mentioned. Thanks .:mrgreen:

Hello there,

I was wondering if a database management library would be something nice, 'cos it won't be necessary to install a database management system before using a program that uses a database.
So, I've developed a database management library, DBL, and I would like to share it with C++ programmers. As soon as I can I intend to share the source-code as well.
There is also a DBL Command-Line Interface for download.

I reckon it might be useful for loads of C++ programmers
