Thinking today, completing a personnel management system project, which features need to achieve?
Such projects commonly described as follows:
the amount of information and type of personnel management information more and more, workflows become increasingly clear division of labor is getting smaller, the original manual processes and stand-alone management system in the traditional can not be more meet the needs of personnel management, personnel management can not meet the needs of enterprises under the new situation. Therefore, it must have used in the Internet age to adapt to the new personnel management system on demand. The new system calls for the traditional C / S model, while effectively managing enterprise personnel information, but with the network society, requiring B / S mode is increasing. B / S model can facilitate the needs of customers and employees to a large extent, in any place, as long as access to Internet, you can obtain business-related personnel information.
SSM (MYECLIPSE) for this framework and its projects, the idea of using the MVC can greatly reduce duplication of effort. And SSM (MYECLIPSE) framework with the best development tools is MYECLIPSE. MYECLIPSE integrates a large number of plug-ins, you can better use the SSM (MYECLIPSE) for development projects, while making more effective project development.
Through careful analysis of the system of personnel management system, personnel management system can be drawn is a background system project.
In such a project, the system login role is essential for each login role is set account and password. To ensure the system can log in normal use. SSM (MYECLIPSE) contained in the project administrator login role, employees.
There is any relationship between the system staff, we will save their relationship in the payroll. Their relationship is such that wages and salaries of employees of the corresponding field and mingzi, wages and employee id id field staff of correspondence
. In order to complete the function of the system needs to be sector employees to set tables, records, employee information. It defines the relationship between the two in the employee table, where mingzi field staff of departmental correspondence, id field counterpart id and department employees
.
The summary results for all data systems: the administrator (admin), wages (gongzi), employees (yuangong), department (bumen)
