dc.description.abstract Utility or value function can be used to represent preferences. In many applications, there is a need to search a da tabase of products for a product or set of produc ts that have highest value computed from a submitted utility function. Such application may be implemented with the help of a database management system. However, with the relational database management system, we n eed to compute the value of every product in the database; therefore time complexity will be large O(N). This is acceptable with small database but it will significantly slow down the overall performance of the system with large database. This study is to apply hierarchical cluste ring to the problem of product database management to improve searching speed. The author discusses a technique for building the database, which uses product abstraction in hierarchical form to speed up the utility- directed searching speed. The efficiency of the proposed technique is evaluated by comparing its performance to that of a system which reli es on a relational database management system.
