The Optimization Algorithm Design of Heterogeneous Database Query
Gan Leib · Journal of Tangshan College · 2013
The traditional structure model builds user interaction models among heterogeneous database,and the system usability is low but quite complex.Through the analysis of the query algorithm design,the public mode of unified access to the system is established;a optimization algorithm based on semi-join operating is put forward.Experimental results show that the query time is reduced compared with full connection and the system performance is improved.
