Mobile Database Procedures in MDBAS
نویسنده
چکیده
MDBAS is a prototype of a multidatabase management system based on mobile agents. The system integrates a set of autonomous databases distributed over a network, enables users to create a global database scheme, and manages transparent distributed execution of user requests and procedures including distributed transactions. This paper highlights the issues related to mobile database procedures, especially the MDBAS execution strategy. In order to adequately assess MDBAS’s qualities and bottlenecks, we have carried out complex performance evaluation with real databases distributed in real Internet. The evaluation included a comparison to a commercial database with distributed database capabilities. The most interesting results are presented and commented.
