Express Delivery Service

Delivery service information system. Made by order of my professor. There are 3 users in the system: client, admin and employee.

  • Client

The client can create, update and delete his orders,
as well as change personal data in his personal account.

  • Employe

The employee can accept the order, fulfill it or refuse,
change personal data in the personal account.
A system is available for him, in which it becomes possible
to select the order that is closest to the employee.

A similar system exists in all aggregators for dating.

  • Admin

The administrator can delete, update all orders.
And, if desired, create new ones. He can also change his account data
if he sees fit.

He does not have access to changing customer and employee data.

Details


  • Implemented cascading update and deletion of data
  • An algorithm for calculating the cost of the order has been implemented

Which depends not only on the incoming parameters in the form of the cost of
the cargo or the size of the box. And also from the distance where you need to deliver this package.

Formula:

TotalCost += BoxHeight * BoxLenght * BoxWidth / 30;   // The cost depends on the size of the box.
 
TotalCost += ProductCost / 5;   // The cost also depends on the value of the item being transported.

TotalCost += ProductWeight / 10;   // And also from his weight.

if (AvailabilityOfInsurancePurchased)  // It is possible to choose insurance if you want,
  TotalCost += ProductCost / 10;       // but then the cost will increase by 10% of the value of the transported item.
  
if (PackagingPurchased)   // Packing the goods in a special way will also increase the cost of the order.
  TotalCost += 150;
  
if (ComplianceTemperatureRegimePurchased) // If the goods require proper temperature conditions during transportation.
  TotalCost += TotalCost / 100 * 20;      //Then its cost of the entire order will increase by 20%
  
double distance = /* Here is the distance between the points. */ ;

TotalCost += distance / 1000 / 100 * 20; // The cost of transportation also depends on the distance.

Technologies

This is a software environment, a necessary component for the operation
of applications developed using this very environment.

UI rendering technology and architecture design pattern.

Used as an ORM. I used SQLite as a database because I needed
a simple and fast solution that would allow me to store data in a structured way.

Used for working with google maps.

Unit testing tool.
