Based On J2ee Erp Enterprise Human Resource Management System Design

This essay, taking the human resources management system of Jiyuan Steel and Iron Group as the background, makes detailed demand analysis and finds that the current human resources management system is unitary in function, which includes only wages accounting and personnel management and doesn't extend to the category of overall enterprise management. In view of such situations, the essay studies and sets up an efficient and highly integrated ERP enterprise resource planning system which is combined with the accounting and production system.Above all, the essay makes theoretical study about ERP human resources management system and J2EE, including the study of the functions of ERP human resources management system, the study of the key factors of implementing ERP, the study of the systematic structure of J2EE, the study of the multi-layer model, technical specifications and the module of the program. For the requirements of good flexibility, sound safety, satisfying the features of distribution, being able to load large access amount put forward by the group and for the system being of good expansion and grafting in order to develop sustainably, the essay fixes the way of applying the pattern of multi-layer distribution structure based on J2EE to realizing ERP human resources management system.The essay also studies further how to construct powerful data accessing layer, proposes separating the data accessing operation on the bottom layer from the professional logic on the upper layer and designs DAO data accessing objects. In DAO data accessing objects, DAO can be used to draw and pack all the accessing to the data source, to connect DAO management and the data source and to provide universal accessing methods for all the customers. This model can separate the data accessing operation on the bottom layer from the professional logic on the upper layer so as to construct powerful data accessing layers. On this base, ERP human resources management system based on J2EE multi-layer structure is realized.
