    namespace Database;
    class Column{

        private $field;

        private $type;

        private $extra;

        private $not_null;

        private $primary_key;

        private $unique_key;

        private $foreign_key;

應該寫成：

    namespace Database;

    class Column{
        private $field;
        private $type;
        private $extra;
        private $not_null;
        private $primary_key;
        private $unique_key;
        private $foreign_key;

分段落

通常 namespace 會跟 class 分開

datebase.php

namespace Database;
use \PDO;
use \Exception;

改成

namespace Database;

use \PDO;
use \Exception;

install.php

function loadDataToTableFromCSV($db, $tableName, $filename){
    $datas = []; //ther storage for datas;

    if (($handle = fopen("data_csv/" . $filename, "r")) !== FALSE) {
        $datafields = fgetcsv($handle, 1000, ",");

        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            array_push($datas, $data);
        }

        fclose($handle);

        try {
            $db->insertIntoTable_batch($tableName, $datafields, $datas);
        } catch (Exception $e) {
            echo $e->getMessage();
        }
    }else{
        throw new Exception("loadDataToTableFromCSV(): this file can't open!", 1);
    }
}
