The main purpose of this paper is to show the advantage of using a model proposed by us, which minimizes roundtrip response time versus traditional models that minimize query transmission and processing costs for the design of a distributed database with vertical fragmentation. To this end, an experiment was conducted to compare the roundtrip response time of the optimal solution obtained using our model versus the roundtrip response time of the optimal solution obtained using a traditional model. The experimental results show that for most cases the optimal solution from a traditional model yields a response time which is larger than the response time of the optimal solution obtained from our model, and sometimes it can be thrice as large
