| 摘 要： | 基于关系数据库,探讨实时数据在关系表中的压缩存储和访问技术.采用Oracle数据库内部语言,对给出的压缩方法加以实现.程序运行结果表明,针对大量的实时数据具有良好的压缩效果,压缩后数据量急剧减少,在数据时间间隔频率不高和采集点数较少时,给出的方法可作为实时数据库的替代方案.

| Abstract: | The compression storage and accessing technology of real-time data in relation table is discussed based on relational database,and the inner language of Oracle database is used to program compression algorithm that will be presented.The experiments show that the effect of compression is very good for larger numbers of real-time data as the number of data would reduce rapidly.In the condition of low interval frequency and less gathering item of data,the presented methods can be used as the substitute scheme ... |
