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

contract DataStorage {
   
        // This is how we declare state variables
        uint256[] public data;
   
        // This is how we declare a function
        function uploadData(uint256[] _data) {
            data = _data;
        }
        function getData() constant returns (uint256[]) {
            return data;
        }
    }
