This is the question create a use case related to this problem. Create a sequence diagram based on the use case and a class diagram

Consider a consulting company with a number of employees (consultants). The company offers a number of services (jobs) to clients. Each job is paid for according to some fixed rate (may be different for each job type), for example "SQL tutorial, rate: $200 per hour". Consultants may undertake a number of jobs a day, each over different periods of time. At the end of each job. a consultant would enter their name and identification number into a computer system, the start and end time they worked on the job, the job description and identification number, and the date. For example: "john smith; J3001; 08:30; 10:00; SOL tutorial; SQLTUT, 27-3-04" At the end of each week the system calculates a payment for each employee based on the total number of jobs undertaken by each one during that time. In order to maintain company expences, the system keeps a 5% of the grand total of senior consultants, and a 20% of that of a junior consultant Create a UML use case diagram and sequence diagram to capture the creation of all weekly payments (5+5 points). Create a UML class diagram for the subsystem responsible to create payments (5 points). An object relationship diagram is also needed (5 points)
