Design of Large Scale RDF Data Storage System Based on Orthogonal Coding

传统数据储存系统是在分布式数据库跨区域储存的基础上实现的,其系统结构复杂,数据储存完整量低且数据存储耗时长。为此设计了基于正交编码的大规模RDF数据存储系统。结合正交编码技术,确定正交频率编码的关系,构建预编码函数和解码函数,利用正交编码处理位置信号,组成编码状态数据,获取动子实际位置;依据缩小储存空间与加快数据取读速度的设计原则,利用布尔矩阵分解的方法,合理布局RDF数据存储并进行数据转化,通过规划系统电路,设置控制模块、硬盘操作模块与数据传输模块,完成RDF数据存储系统设计。仿真结果表明,上述系统能够提高储存完整量,有效降低存储消耗时间,提高存储效率。

Traditionally,the data storage system was based on cross-regional storage of distributed database.The system structure was complex and the data storage time was too long.Therefore,this article designed a large-scale RDF data storage system based on orthogonal coding.Firstly,we combined with orthogonal coding technology to determine the relationship between orthogonal frequency codes,and thus to construct precoding functions and decoding functions.Secondly,we used the orthogonal coding to process position signals and construct the coding state data,so that we could obtain the actual position of the mover.According to the design principle of reducing storage space and speeding up data reading speed,we used Boolean matrix decomposition to rationally arrange the RDF data storage and perform the data conversion.By planning the system circuit and setting the control module,hard disk operation module and data transmission module,we completed the design for RDF data storage system.Simulation results show that the designed system can improve the storage integrality,effectively reduce storage time and improve storage efficiency.
