Small Database Answers for Small Mobile Resources
نویسنده
چکیده
Useful mobile database access depends on available resources of handhelds and wireless networks. Smaller database answers cope better with this situation. The bene ts of smaller database responses are faster transfer times, and therefore, smaller transfer costs, and decreased power and memory consumption of mobile devices. Existing research approaches for data reduction do not exactly meet reduction requirements of mobile environments and especially their restricting conditions. Approximate answers are sometimes insu cient and fast transfers of answers over wireless links are more important than short execution times on xed sites. In this paper, we study database techniques that issue smaller answers by restricting the quality or the quantity of data to meet resource requirements. We outline various reduction mechanisms and present a hybrid technique of a designed and a progressive technique for supporting mobile users.
