Nowadays, corporations have to consistently advance the value of human assets in their own organizations for maintaining their competitiveness. To achieve this goal, the Human Resource (HR) Dept. plays a decisive role in the aspects of selection, training, employment, and retaining of human resource in the organization. How to improve the efficiency of the HR Dept. and enhance its status in the organizations has become the top agenda to enterprises. The development of Information Technology (IT) transforms the role of the HR Dept. in the organization. It enables HR to be a real strategic partner of corporations through the process of Organization Development. A Human Resource Information System (HRIS) based on the network technology will change the working environment of HR and further lead the transformation of the functions and roles of the HR Dept. Through conducting interviews with 9 companies, this research tries to answer the question, that is, what is the impact to the effectiveness of Human Resource Management when a HRIS is leaded in. It used literature research to analyze the characteristics of Human Resource Management (HRM) and HRIS and sorted out the possible impacts. It also used case study to sharpen the insight by sampling 9 companies which had used HRIS, including foreign and local ones. By doing the work, it drew a conclusion of the impact brought by HRIS and provided a direction of HRIS vendors. The study found that the factors of successfully leading HRIS into a company include the integration with original data, combination with the existing Enterprise Resource Planning System (ERPS), the compatibility of the existing HRIS, HR people¡¦s inability of maintaining HRIS, the suitability of HRIS for company¡¦s specific needs, and the support from high-level management. Leading in a HRIS could benefit the company from decreasing the inconvenience of human operations and increasing the quality of HR¡¦s services. The impacts on the effectiveness of HRM can be seen as the indexes which have positive reaction to HRIS: 1. Reward Management: HRIS provides fast calculation of payment and less human operations. Its tracing function in Payment Module and integration with ERPS help data exchange between HRIS and ERPS. 2. Training Development: HRIS keeps thorough training records of employees. It also can display the average training hours per person, training cost, training results, and etc. 3. Appraisal Management: The whole appraisal process can be done through HRIS, even crossing areas. 4. HR Strategy and Planning: Since HRIS is able to provide more precise data analysis, the quality of decision making of high-level management is enhanced with a great progress. 5. Team Management: Through humanity design of HRIS, more participation from employees is involved. Management spreading in different places still can use HRIS as a platform to exchange HR related information.

For being in this changed rapidly new economic era, network technology has brought significant reform for enterprise operational mode, human resource information system has developed with the advantage of information technology, and become a necessary manage instrument gradually, adopt systematic and statistical analyze mode, collocated to display with visional graphic table (such as analytic form or statistic sketch), let high-level and human resource chief be capable of scientific and specific policy assistant data. Data Warehouse is a new technology for data storage, within the data warehouse not only could compile data, even more proceed to decompose¡Bmerge and intersect in different range and layer, and then utilizing the function of On-Line Analytical Processing (OLAP) or Data Mining to obtain one step ahead of information, providing applicable message for policy maker. Therefore, in recent year, data warehouse has become the main data source of Decision Support System (DSS) gradually. This research attempts to establish a data warehouse fledgling model for human resource management, providing the basic requirement for rapidly inquire related statistic data for policy maker, and extract data from human manage information system data base, establish a related multiple dimension data model. And apply the technology of Data Warehouse and OLAP, via Internet, policy maker could depends on his requirement inquiring related statistic data elastically and rapidly, and enhance the quality and time effectiveness of decision. This research could establish the systematic benefits as below¡G ¢¹.Provide convenience to inquire data: via mouse proceed dragging action, rapidly and time effectively let user operate conveniently in data inquiring procedure. ¢º.Multi-dimensional analyze data: owing to OLAP could support multi-dimensional inquire, and makes different intersect analyze and variation comparison, could let the manager make decision reference material more explicitly. ¢».Obtain necessary information elastically: could depend on user¡¦s requirement, arbitrarily change dimension, obtain necessary information, increase user¡¦s inquiring elasticity. ¢¼.Via network medium access: establishing the base system by web-base, via network and browser could forward to inquire, enhance the system¡¦s mobility and convenience. ¢½.Function of data base examination: through OLAP statistic outcome, could reach examine database correctly and completely.
