You need to install the database (MS SQL or MySQL) on the server and create the database 'InventoryDatabase' on the server and then use following connection string in the web.config
<add name="InventoryDatabaseConnectionString" connectionstring="Data Source=Name\INSTANCE;Initial Catalog=InventoryDatabase;Integrated Security=True" />
after that configure the webserver (IIS or Apache) for the website using the path where you copied the file on the server.
