Objectives and requirements of course design
Wage management and personnel management, the actual production of every employee of the enterprise salary.
The basic information of enterprise staff and personnel includes employee number, name, gender, date of birth, professional title (assistant, engineer, senior engineer) and length of service.
Enterprise worker salary information includes: worker number, name, duty salary, duty allowance, housing allowance, should pay salary, individual income tax, endowment insurance, housing accumulation fund and pay salary actually.
The main functions of the system include:
(1) Create the basic information file of staff and personnel, input various information of staff according to prompts, sort the staff information according to the number of staff, and store the sorted staff information into one file.
(2) Create the salary information file of the employee (create 1 file every month), in which the employee number and name are copied from the personnel information file. Other salary components shall be calculated according to the following method.
Salary on duty: assistant =1270*(1+ years of service *2%)
Engineer =2360*(1+ years of service *3%)
Senior Engineer =3450*(1+ years of service *5%)
Job subsidy: = job salary *25%
Housing allowance = (duty salary + duty allowance) *15%
Should pay salary = duty salary + duty allowance + housing allowance
Personal income tax = (payroll -3000) *5%
Endowment insurance = (duty salary + duty subsidy) *10%
Housing accumulation fund = salary payable *5%
Pay salary = should pay salary - individual income tax - pension insurance - housing provident fund
(3) Increase the basic information of staff and personnel, and add the new information of staff and personnel on the basis of the original basic information files of staff and personnel.
(4) Delete the basic staff and personnel information, prompt the user to input the employee number to be deleted, if the information exists in the file, output its information to the screen, the user will confirm the deletion of the information, and save the deleted results to the original file. Finally, the user is prompted to continue with the delete operation.
(5) Modify the basic staff and personnel information, prompt the user to input the employee number to be deleted, if the information exists in the file, output its information to the screen, then prompt the user to modify the options (title, tenure), and save the modified results to the original file. Finally, the user is prompted to continue the modification operation.
(6) Conduct inquiry operation according to different conditions, and output the salary information of employees meeting the conditions.
(1) according to the employee number query, input 1 number, output corresponding employee salary information.
(2) query by name, including precise query, fuzzy query.
(3) Query by professional title, input professional title name, output the corresponding professional title salary information.
(7) According to different conditions of the wage information for the statistical work.
(1) Statistics of the number of staff and workers in posts of professional titles is how many, calculate the proportion of senior engineers.
(2) calculate the average real wages of enterprise employees, and output.
(3) statistics of the number of workers whose wages are lower than the average wage, and output their names and real wages.
