The JScript .NET component OrdersDB.js handles the business logic of the IBuySpy Store orders. In particular, it extracts orders from the database, adds orders to the database, and computes the shipping date.

All IBuySpy components share the same IBuySpy namespace. The OrdersDB.js component includes two classes: OrderDetails and OrdersDB. The OrderDetails class includes only parameters:

  public class OrderDetails {
    public var OrderDate : DateTime;
    public var ShipDate : DateTime;
    public var OrderTotal : decimal;
    public var OrderItems : DataSet;
  }
The OrdersDB class is the main class. It includes the following method declarations:

  public class OrdersDB {
    public function GetCustomerOrders(customerID: String) : SqlDataReader {...}
    public function GetOrderDetails(orderID: int, customerID: String) : OrderDetails {...}
    public function CalculateShippingDate(customerID: String, cartID: String) : DateTime {...}
    public function PlaceOrder(customerID: String, cartID: String) : int {...}
  }
