Wireless data broadcast allows a large number of users to retrieve data simultaneously in mobile databases, resulting in an efficient way of using the scarce wireless bandwidth.

To properly cope with the inherent property, this paper presents three predaclaration-based transaction processing methods that yield a significant performance improvement in wireless data broadcast.
