ABSTRACT Internet technology has drastically changed the enterprise computing and platform. Database management and systems repre sent the core of the change and the key of the new revolution of the information technology and infrastructure. Business information and models have been stored and manipulated through the use of the database technology. Due to the fast growing speed and variety of the database products in the marketplace, managers are having making the right decision in selecting and maintaining the Internet database management and systems. To tackle this issue, we propose a requirements-based software selection model from the user's viewpoint. In this research, we develop a five-step choice model with an emphasis on the require ment analysis and rank analysis. We collect and compile the func tional and nonfunctional characteristics and features of the Internet database management and systems. We classify and organize them into a four-layer hierarchy and work with the weight mechanism in the rank analysis. This choice model adopts another five-part rank policy in order to produce the final suggestion of software selection. In the end, we apply the new model in a field case study of the Web Database Systems Procurement Project with the National Laboratories of Foods and Drugs, Department of Health, Executive Yuan. Keywords: Internet Database ' Software Selection Model ' Middle ware ' WWW ' Multi -tier client Server - 276 . ~.
