摘要：Data Warehousing is a blend of technologies aimed at effective integration of operational database into an environment that enable strategies use of data. These technologies include relational and multidimensional database management system, client/server architecture, metadata modeling and repositories, GUI and much more . In Data Warehouse , data quality which implies the data is accurate, timely and consistent for mak ing deci sion s . During this study we have identified the different data quality parameter s . These parameters play a very vital role in the information generation. A good quality data can produce quality and more authentic information which can be effectively used for decision making in the business environment . Manual verification of quality of data is much difficult and thus we have proposed a system for automatic data quality verification mechanism in this paper. The Data quality parameter slike : accuracy, consistency, completeness , uniqueness, validity are some of the selected one which affect a quality index with gr eat extent. We have to proposed a system which check whether the data under examination is accurate or not by using syntactic accuracy and semantic accuracy and data is complete or not by using value completeness, tuple completeness, attribute completeness , relation completeness etc
