In modern databases data quality is crucial problem. Data-entry forms grant the primitive and supportable opportunity for identifying and modifying errors, besides, for upgrading data quality at entry time, there has been a provincial research into automatic procedures. In this paper, the authors propose USHER, which is an end-to-end system for designing a form, entry and data quality assurance. From the previous form submissions, USHER attains an apparent model over the form questions. At every step of the data-entry process, USHER applies this model to improve the data quality. It induces a form layout which obtains the frequent data values of a form immediately and deducts the complication of error prone questions before entry of the data values.
