Database API

Database server setup

The overall setup on the server looks similar to this (fetched from this website: https://www.simplifiedcoding.net/android-mysql-tutorial-to-perform-basic-crud-operation/

The mobile application sends an HTTP request to the server through the PHP API. If the request is a valid API request the data is either stored or retrieved from the database.

Changes

When changing database structure or API remember the dependencies to the PHP API and the code of the devices using it.

Code:

• Database (on server)
• Java API string (and related classes that implement URL, any or all of these)
• PHP code (on server)
  • ClimAppAPI.php (create new version)
  • DbOperation.php

Documentation:

• Database
  • Generate new ER diagram and add in Database
• Database API (this)
• Visio
  • API calls and parameters
• Database update triggers

API

Created on the server hosted by DTU Byg. All parameters are shared preferences, each parameter links to the related preference description.
