1. Read the Asg_RH documentation and draw a use case diagram. According to the requirements of Task1, please use the tool UMLet, the screenshot format must be png and control the size
2. Select a hotel booking online service system (or mobile APP) that you are familiar with, such as drawing a use case diagram. And meet the following requirements: Compare the Asg_RH use case diagram, color-coded innovative use cases or sub-use cases
3. Compare the use case diagrams of products in two eras and different regions, summarize the early stages of the project, and discover innovative ideas and methods
In the early stage of the project, it is necessary to realize the basic functions well, and then think about the key places based on the basic functions, such as the places where customers need to choose, to realize functional innovation and better serve customers.

| Detailed use case | All steps and changes are detailed | more time |
| casual example | Less time and cost while covering multiple scenarios | Insufficient details to directly serve as a basis for implementing code |
| brief example | Concise and concise summaries that take less time | lack of detail, lack of detail |
