A New Architecture Model of Mobile Database Based on Agent

摘要

In mobile database systems, new features such as mobility, disconnection, heterogeneity, self-command and distribution make traditional transaction processing schemes such as query processing technology, transaction management technology and data distribution technology no longer suited. To solve this problem, a new mobile database model based on agent was proposed. And transaction processing process based on this model was set forth. The model can shield the heterogeneous among all members, and made them transparent so as to bring great conveniences to the entering of heterogeneous members. The introduction of mobile agent contributes to decomposition of long-lived transaction, as to complete query optimization of mobile database.
