Design And Implementation On Person-Wage Information System Based On COM

With the rapid Development of Networks and Communication, IS especial MIS is widely used. In them, Financing System is becoming an important measure to supervise finance ~. to enhance management and to help decision梞aking for enterprise and service's organ. At present, Financing System is usually constructed by 2-tiered C/S framework. There are several disadvantages in 2-tiered C/S framework , such as resource wasted seriously, Connection of multiple users and multiple Databases- Management of Security, upgrade and maintenance of software becoming difficult. So software of Financing System must be constructed by 3-tiered C/S framework. And the design and achievement of middle layer is key part to construct high efficiency, strong and secure MIS. COM (Component Object Model ) refers to a software framework regardless of the operating system and programming languages , which is produced by Microsoft Co. Characteristics of language independent , process transparent~ software reused and more secure are fundamental of it. The aim of COM's programming is to divide the application into dependent models, which run at same machine or different machine ,even different OS. As soon as requirement of application is changing, there is no necessity to modify whole application but models changed. It integrates function-software into applications by plug-and-in mode, which makes the software easy to design, upgrade and maintain.. In this paper, Wage System is constructed by 3-tiered C/S framework. The middle layer's Model including management of Department and Person, management of Wage Items and Wage Info, management of Person Items and Person Info, management In of Wage Standard Table and Wage Compute are COM program, MTS is also used There are several advantages for Wage System above. Such as software reuse and management of security is enhanced upgrade and maintenance of software becomes easy. Besides, Wage System has other new virtue: Wage Standard Table is consistent with Structural Wage system of our country. Also Computed Items meet the demands of Wage innovation-- Position and benefit's Wage System. User can define Person Items and Wage Items freely. The input of data is reduced to lowest level. The Structure of Depart and Person is laid out as a tree, So appearance keeps consistent.
