Deployment Diagrams

Using deployment diagrams, we explicitly describe the physical structure of our software and related hardware. We deployed the first segment on the browser, which combined with the local server. According to the combination of data and background, a series of functions of the software are shown. For example, user login, food nutritional value and so on. Deployment Diagram

Class Diagrams

Using class diagrams, we can better understand the programming requirements and which classes need to be provided to support the connection and operation of the software. We have user Class, nutrition Class, food Class and food diary Class.

Behaviour : Sequence and/or State Diagrams

Sequence diagrams are used to more visually describe the relevant use cases and show the sequence of steps involved when a web site executes a request. For example, if a user wants to add food, they should first enter the page of adding food, click the food they want to add, send a request, and get the request in the background and other relevant interactions in the foreground, server, database and background.
