◽ Objective

• Create an instance of Azure Digital Twins by using the Azure portal.
• Create digital models for the production line of a chocolate factory.
• Validate the digital models by using the validator sample.
• Create a graph of the models by using the Azure Digital Twins explorer sample.
• Query the graph by using SQL-like queries.

◽ Scenario of HOL : A chocolate manufacturing company(Contoso Chocolate)

The following image shows the production line:

① Roasting
The roasting process cooks fermented cocoa beans. The temperature and time of cooking depends on the type of beans, but typically the roasting (sometimes called fanning in the chocolate trade) might take 35 minutes at 250 to 300 degrees Fahrenheit. Roasting aids the removal of unwanted stuff, such as acetic acid, and the formation of the sweet taste of cocoa.
② Grinding
The grinding process takes the cocoa nibs that result from the roasting and crushes them to pieces, typically between steel plates, to create a liquid cocoa butter.
③ Molding
The molding process cools the cocoa butter in molds, giving the desired shape: chocolate bars, egg shells, and figures. The following image shows roasted cocoa nibs:
