| Abstract: | The equivalence matrices algebra is extend to describe the low approximation,the upper approximation,rule extraction,relative core and relative reduction.A prototype system has been designed and implemented in authors' research,called RSORDMS,adding data mining capabilities to ORDBMS while preserving its traditional power.In the prototype system,a technique is adopted which combines rough set with SQL to make data cleaning and core computation fast.The whole prototype system has a good performance. |

| Keywords: | rough set ORDBMS core data mining equivalence matrices algebra |
