Filip's Design Study

Background

My design study is related to my part time job, where I am developing an application that can retrieve and plot data from a device that monitors air quality. The application is connected to a back end server where certain data is stored.

User operations that require communication with the server roughly include:

• Requesting help (and that the user be contacted)
• Electronically registering a device
• Calibrating a device - data about the calibration process is uploaded

Additionally, server communication is needed when the application:

• Authenticates with the server
• Pings the server to ensure network connectivity

My goal here is to create a design for the application side server interface framework. HTTPS POST requests are to be used to transfer data to the server.

Requirements

As this is a just a part of the app, the requirements are largely self imposed & generic:

• something that works
• is as nicely designed as practical
• is as easy to understand and maintain as practical
• is flexible so that new server requests can be added without much hassle

And not to forget:

• apply & learn better OO techniques

Deliverable Design

• Classes that model the different request types
• Classes that allow requests to be sent over the network
