The Data Check-up Based On Knowledge Base

With expansion of database use, relational database not only is approved by the masses of users, and people put forward new request constantly with this, hope and can make high quality of analysis of data in time. In addition datum that need to be dealt become more and more large, and mistakes of data appear unavoidably among them. So data check-up becomes one of the main subjects studied.This paper, in order to realize data check-up based on knowledge base, analyses in depth the rule, reasoning in the expert system in artificial intelligence field, the defect of data restrain in the traditional database and improvement on the data check-up based in knowledge base. Here we describe knowledge representation model oriented entity, database conversion, instantiation of the knowledge base, rule editor and data check-up algorithm.With platform of knowledge base transformed from database, we can do much work on it. Data check-up only is an application respect among them. We can also make data analysis on this platform. So combination of artificial intelligence and traditional database will solve a large number of problems that exist in the computer practical application field, and make contribution to the information construction of all trades and professions.
