Elema is the project for the course "Project Workshop of Database Systems" (CS357, SS2017) of SJTU. The aim of this project is to create a food-delivery system similiar to the Chinese webpage "ele.me".
The system consists of a backend including a webserver hosting the webpage, an interface written in PHP and a MySQL database storing all information, as well as a webpage as the frontend.
To install the system on the local machine, at first an Apache Webserver and a MySQL database as well as PHP must be installed. The contents of the directory "website" must be placed into the "www" (or "htdocs" in some cases) directory of the Apache server. The SQL script "elema.sql" in the directory "Database" must be executed on the MySQL server. It will create necessary databases, tables, users, views, constraints and triggers. The webpage can now be accessed over "http://localhost" and the admin panel over "http://localhost/control".
