To get the version of the application up and running within your local development environment, all of the following steps need to be completed:

• Add .env files to the backend/customer-support, backend/order-processing, and frontend folders (based upon the available .env.example files within each of those folders).

• Create the customer_support and order_processing databases as well as their respective users customer_support_app and order_processing_app using the following SQL statements:

create database customer_support;
create user customer_support_app with encrypted password '«the customer_support_app user password»';
grant all privileges on database customer_support to customer_support_app;

create database order_processing;
create user order_processing_app with encrypted password '«the order_processing_app user password»';
grant all privileges on database order_processing to order_processing_app;

• In the backend/catalog-management folder, install the sub-project's dependencies by running the command npm install and run the command npm start to start the application.

• In the backend/customer-support folder, install the sub-project's dependencies by running the command npm install, apply the Sequelize migrations and seed data by running the commands npx dotenv sequelize db:migrate and npx dotenv sequelize db:seed:all, and run the command npm start to start the application.

• In the backend/order-processing folder, install the sub-project's dependencies by running the command npm install, apply the Sequelize migrations and seed data by running the commands npx dotenv sequelize db:migrate and npx dotenv sequelize db:seed:all, and run the command npm start to start the application.

• In the frontend folder, install the sub-project's dependencies by running the command npm install and run the command npm start to start the application.
