Firstly, install MariaDB Server. Once installed, open the MySQL Client and press Enter when prompted for the password. Then enter the following:
CREATE DATABASE db;
Next, open cmd and navigate to the installation's bin folder, by default:
cd C:\Program Files\MariaDB 10.5\bin
Then enter the following (where %sql_file% is the absolute file path to the db.sql file in the project's root directory):
mysql -u root -p db < %sql_file%
Press Enter when prompted for the password.
To run the server, open the project in IntelliJ and go to Run → Run 'Server'.
To run the client, open the project in IntelliJ and go to the Maven Tool Window on the right-hand side. If it's not open, go to View → Tool Windows → Maven. Within the Maven Tool Window open the cab302-major-project dropdown, go to Lifecycle → compile. Once compilation is complete, click on Reload All Maven Projects at the top left of the window. Then go to Plugins → javafx → javafx:run.
Within the Maven Tool Window open the cab302-major-project dropdown, go to Lifecycle → package. Once the packaging process is complete, the executable jars and their properties files can be found in the target directory in the project root.
