Create code in solidity that uploads data files, then create smart contract for the files

// compile the contract
pragma solidity ^0.4.15;


contract Data {
    uint256 public timestamp;
    string public data;
    uint256 public price;
    
    function addData ( uint256 _timestamp, string _data, uint256 _price) {
        timestamp = _timestamp;
        data = _data;
        price = _price;
    }
    
    function getData() constant returns (uint256, string , uint256) {
        return(timestamp, data, price);
    }
}
