对网络数据库进行访问路径优化控制,提高数据访问调度能力.传统的网络数据库访问路径控制采用关联特征分析的平均互信息法进行关联维提取,当关联维特征出现独立同分布状态时,提取性能受限,导致数据库访问路径失控.提出一种嵌入权向量编码的数据库优化访问路径控制技术.计算权向量编码信息,通过权向量编码,得到数据库访问路径控制的信息增益为二叉分类回归编码信息,实现对数据库访问路径状态空间优化重组,提高控制能力.仿真实验表明,该算法进行大型网络数据库的数据访问和调度,具有较少的时间开销,提高了数据访问的吞吐量,有效提高数据库访问控制的性能,减少访问路径偏移,具有较高的特征贡献率.

In order to access path optimization control of network database, improve the ability of data access scheduling. Path control using association analysis of the characteristics of traditional database access network the average mutual infor-mation method of correlation dimension extraction, when the correlation dimension show characteristics of independent and identically distributed state, extraction performance is limited, resulting in loss of control of database access path. An em-bedded power vector coding database access path control technology proposed optimization. Calculate the weight vector en-coding information, the weight vectors encoding, get the database access path control information gain return code informa-tion as two forks classification, implementation of access path state space restructuring and optimization of database, im-prove the control ability. Simulation results show that, the data access and scheduling algorithm of the database, with less time cost, to improve the data access throughput, effectively improve the performance of database access control, reduce the access path offset, it has a big features contribution rate.
