The rapid increase in the use of many commercial software products has necessitated a systematic and objective method of their evaluation and selection. Our study focuses on the assignment of weights and choice of proper models. First, the weights of attributes are assigned consistently by using the analytic hierarchy process. Second, many models, which can be suitable for the structure of evaluation and selection for software product, are collected, categorized into two types of model, and compared in terms of their strength and weakness. The models involved are four compensatory models and seven noncompensatory models. Finally, they are analyzed through the application of specific software products(database data modelers) in terms of their attributes. Our study enhances the applicability of models to a variety of user requirement utilizing the evaluating procedure and applications.
