Design and realization of employee's salary management

Functional Design Requirements

1. Enter records: Each employee's name, ID number and basic salary, dominate, post allowance, medical insurance, Provident Fund data as a record. The software can create a new data file or add records to an established data file.

2. Display records: According to the user-provided records or according to the name of the employee shows the wages and average salary of one or several employees.

3. Modify the Record: You can modify the data of any record of the data file and display the contents of the record before and after the modification.

4. Find records: You can look up data from any record in a data file and display the contents of the record before and after it is found.

5. Delete a record: You can delete any record in the data file.

6. Statistics: (A) The calculation of the average wage and the total wages of wages, (B) The statistics meet the specified conditions (such as the first three of staff wages and above 3000 yuan, 3000~2000 yuan, 2000~1000 yuan) within the number of wage workers and the percentage of total staff. (C) Print all Employee payroll information forms and average wages (including the total average salary) in the form of a character table.

7. Save the data file feature.

For example: Employee Payroll Information Form
