Requirement Analysis for the first project

The training ended in three and a half months.ExtjsIt takes about one and a half months to develop a simple invoicing software. The database structure is approximate and can be used for management.RBACPermission management, database I plan to useMySQLThe demand analysis should be written by myself, and I wrote one by one. The most important thing in invoicing is to add, delete, modify, and query, and expand around this center. For the first time, I did not write a small project, the instructor gave an example document and wrote a little bit in a day. I don't know how to assign RBAC permissions. I have a super administrator and create a new operator. This operator has some functions by default, then, the super administrator can assign and delete permissions to the operator. This is what I can think. I have not learned much today. I have a rough understanding of the table structure and have no idea at all. When I leave, all the people go back to the dormitory. Continue tomorrow.
