在不使用分布式事务的情况下优化此代码

有没有一种方法可以使这段代码比现在更优化，而不使用TransactionScope ?

public static bool DeleteItem(int cusID)
    {
        int result = 0;
        using (OleDbConnection myConnection = new OleDbConnection(AppConfiguration.ConnectionString))
        {
            string delOrders= "DELETE FROM ORDERS WHERE cusID=?";
            string delCustomer= "DELETE FROM CUSTOMERS WHERE cusID=?";
            OleDbCommand myCommand = null;
            OleDbTransaction tran = null;
            try
            {
                myConnection.Open();
                tran=myConnection.BeginTransaction();

                using (myCommand = new OleDbCommand(delOrders, myConnection))
                {
                    myCommand.Parameters.Add("cusID", cusID);
                    myCommand.Transaction = tran;
                    myCommand.ExecuteNonQuery();
                }
                using (myCommand = new OleDbCommand(delCompany, myConnection))
                {
                    myCommand.Parameters.Add("cusID", cusID);
                    myCommand.Transaction = tran;
                    myCommand.ExecuteNonQuery();
                }
                tran.Commit();
                result = 1;
            }
            catch (OleDbException ex)
            {
                tran.Rollback();
                throw ex;
            }
            finally
            {
                myConnection.Close();
            }
        }
        return (result>0);
    }
