Attendance management subsystem 
 1. Introduction 
 Attendance management subsystem card is divided into parameter setting, data preparation, data processing, data reporting and data clearing five modules. In the parameter setting module, in accordance with department scheduling, each class can be divided into Liuduan special circumstances, individuals can follow the shifts, if each department has some staff working in the same system, these employees can be drawn from the sector, according to group scheduling. In the system, individual scheduling the highest priority. Therefore, we can resolve the temporary classes, special classes, does not affect the normal classes originally scheduled, and the scheduling cycle can be set, scheduling system does not limit. In the data preparation module, you can set the date of written request for leave, overtime articles, travel articles and so on. 
 System statistics of each employee's attendance, late, leave early, leave, overtime, travel and other conditions, a customized weekly, monthly and annual statistical reports, but also has a flexible user-defined reports can be defined according to the system in the field by any combination of user needs form their own statements.
