Distributed database systems can dealt with growing amount of data.
On the other hand, distributed database systems have
problems to be solved, such as secrecy, permeability, and so on.
In our lab, to over come those defects, we are proposing a distributed
database system called, a Secret Sharing Distributed Database System.
Because of it's system characterisitc, query processing in the system is
more complicated than those in normal distributed database system.
Therefore, among all the other query processing problem, the objective
of this paper is to optimize subquery assignment to servers which is
strongly affected by secret sharing method.
In this study, problem of subquery assignment to
servers is boiled down to question of combinational optimization
problem.
To solve the problem, we construct a one and only objective function to
adopt existing technique to solve subquery assignment problem in
distributed database system.
According to the computational experiment, we were able to confirm that
the application of the novel objective function is effective in
obtaining a good initial solution in solving the problem. |
